I make this keto birthday cake chaffle every time someone in my house has a birthday. Three cream cheese chaffles stacked with buttercream frosting, and it takes about 20 minutes start to finish.
I started making this birthday cake chaffle because I wanted something that actually felt like a celebration, not just another “keto dessert” that everyone politely eats. Three cream cheese chaffles layered with real buttercream frosting, and the whole thing comes together in about 20 minutes. If you want a full-size layer cake instead, I have a keto vanilla birthday cake that works too, but this chaffle version is what I reach for when I need something fast.
The batter is simple. Egg, cream cheese, almond flour, a little heavy cream, and cake batter extract for that unmistakable birthday cake flavor. I blend everything until completely smooth because that’s the part that matters most. When I first developed this recipe, I had batches come out floppy and dense. The fix was getting the cream cheese fully incorporated, no lumps hiding in the batter. If you watch the video above, you can see exactly what the consistency should look like before it goes into the waffle maker.
One thing I love about cream cheese chaffles is that the cream cheese acts as a natural non-stick agent. I never spray my waffle maker for these. Pour about a third of the batter into the center, close the lid, and give it a full 3 minutes. You want these spongy, not crispy. They need to be soft enough to absorb the frosting and hold together as a layered cake.
The frosting is a basic keto buttercream. I cream the butter until it goes pale (the longer you beat it, the fluffier and lighter it gets), then mix in powdered erythritol and vanilla. Add the heavy cream a tablespoon at a time so you can control the consistency. Too much cream too fast and you end up with something too thin to frost with. I like mine thick enough to hold its shape on the sides.
If you love chaffles as much as I do, try my keto chocolate chaffle or the lemon chaffle with lemon icing. And if you want another quick birthday option, my birthday mug cake is ready in under 5 minutes.
One of my readers, Laurie, doubles the recipe and makes it in a full-size Belgian waffle maker. She freezes the extras with parchment paper between layers so she always has birthday cake chaffles ready to go. I’ve started doing the same thing, and it’s become my go-to move for last-minute celebrations. Pull them from the freezer, let them thaw for about 10 minutes, frost, and you have a keto birthday dessert that nobody believes is low carb.

Step by Step Instructions
Step by Step Instructions
Whisk it
Whisk together all the chaffle ingredients – egg, cream cheese, almond flour, baking powder, heavy cream, monk fruit, vanilla and cake batter extract.
Pour batter
Pour 1/3 of the chaffle mixture into the center of the waffle iron. Close the waffle maker and let cook for 3 minutes or until waffle set. You want this chaffle to be spongy and not crisp.
Remove & repeat
Remove chaffle from the waffle maker and repeat with remaining batter until you have three cake chaffles.
Make the frosting
Beat the butter in a small bowl. The longer you cream it, the lighter in color it gets. Mix in powdered erythritol and vanilla. Slowly add heavy cream until you reach your desired frosting consistency.

Can I freeze this chaffle cake for later?
I freeze these all the time. I make the chaffles, let them cool completely on a wire rack, then stack them with parchment paper between each one and store in a freezer bag. They keep for about a month. When I'm ready to use them, I pull them out and let them thaw on the counter for 10 minutes before frosting. The texture holds up well. One of my readers doubles the recipe specifically so she always has extras in the freezer for when she needs a keto birthday dessert fast.
What sweetener works best besides monk fruit?
I've tested this with several sweeteners and any granulated blend that measures cup-for-cup with sugar works fine in the chaffle batter. For the frosting, I stick with powdered erythritol because it dissolves smoothly. I'd avoid pure stevia drops here because they can turn bitter when you use enough to sweeten frosting. If you use a different granulated sweetener, just check the package to make sure it's a 1:1 sugar replacement.
Can I make this in a regular Belgian waffle maker?
Yes. I've done it both ways. For a Belgian waffle maker, I double or quadruple the recipe so you have enough batter to fill the larger plates. The chaffles come out bigger and thicker, which actually makes a more impressive layered cake. One of my readers uses a Belgian maker every time and says it's less work since you get fewer, bigger layers. Just keep the heat at medium-high and cook until spongy, not crisp.
Where can I find birthday cake extract?
I buy mine online. LorAnn Oils makes a cake batter flavor that I've used for years and it's what gives these chaffles that unmistakable birthday cake taste. You can also check the baking aisle at craft stores like Michaels or Hobby Lobby. If you can't find it, I've had readers swap in almond extract instead, and one reader added equal parts almond and vanilla to the frosting too. Different flavor profile, but still really good.
How do I prevent the frosting from melting?
I let my chaffles cool completely before I frost them. If they're even a little warm, the buttercream slides right off. I also make sure my butter is softened but not melted when I start the frosting. If you're serving this somewhere warm or bringing it to a party, I keep mine in the fridge until about 15 minutes before serving. The frosting firms up in the fridge and holds its shape much better.
What if my chaffles come out floppy instead of spongy?
I had this same problem when I was testing the recipe. The fix for me was making sure the cream cheese was fully blended into the batter with no lumps. If there are chunks of cream cheese hiding in there, the chaffle won't set properly. I also make sure my waffle maker is preheated to medium-high before the batter goes in. Giving it the full 3 minutes without opening the lid early makes a big difference. My video above shows exactly what the right texture looks like.
Can I make this chaffle cake dairy-free?
I've tested a dairy-free version using dairy-free cream cheese in the batter and coconut cream in the frosting. The chaffles come out slightly denser but still hold together as a layered cake. For the frosting, I use coconut cream that's been refrigerated overnight so it's thick, then whip it with powdered sweetener and vanilla. It's not identical to the buttercream version, but my dairy-free friends have been happy with it. Try my keto chocolate cake too if you want another dairy-adaptable option.
Having a birthday cake on keto is easier than you think! Even if you aren’t a baker, you can make this recipe for chaffle birthday cake. A three tiered cake made out of cake flavored chaffles sits between layers of a creamy low carb buttercream frosting. This smells and tastes so much like real cake! All that’s missing is a 
This dessert is easy to make. You can make anyone a birthday cake in less than 10 minutes. The cake chaffle makes a fun birthday breakfast too!
This chaffle cake is also on the smaller side, so you won’t have tons of leftover cake lying around.
A chaffle is a waffle made with cheese and egg as its main ingredients. This recipe adds vanilla, cream, and cake batter extract to give it a vanilla cake flavor.
Don’t overcook your chaffles for this cake. You want a spongy texture, not a crispy one. Cooking them too long crisps them up, and nobody wants a hard cake!
Any waffle maker will work to make chaffles, but the best one for a three tiered birthday cake chaffle is the 
You can’t have a birthday cake without frosting! A simple sugar free white buttercream frosting is always a hit on a cake.
To make low carb buttercream frosting, just add all the ingredients together and mix until smooth. For that creamy white color, cream the butter on its own for 3-5 minutes before adding anything else. The longer you whip it, the more air gets incorporated and it fluffs up and turns lighter in color.
Made this for my friend's birthday dinner last month (she doesn't do keto and I went in a little nervous). The cake batter extract is what gets you, it actually tastes like real birthday cake batter, not a substitute for it. She kept asking where I ordered it from, and when I told her I made it in under 20 minutes she genuinely didn't believe me. Making a double batch next time so there's enough for both of us.
The 'where did you order it' reaction is my favorite. Double batch is the right call too, three stacked chaffles disappears fast.
First chaffle I've ever made and I went straight for this one because my daughter's birthday was this weekend. I was nervous about the waffle iron step (kept picturing batter everywhere) but they popped right out, and the cake batter extract is what made it. Tastes nothing like a regular waffle with frosting on top. Stacked all three with the buttercream and it actually looked like a real birthday cake. One thing I can't figure out: mine came out soft in the center even after cooling completely. Is that normal for cream cheese chaffles, or do I need to leave them in longer?
Cream cheese chaffles are naturally softer than egg-only ones, so some give in the center is normal. If it felt actually underdone rather than just soft, add a minute in the iron. I cool mine on a wire rack too, not a plate. They firm up more that way.
Never made a chaffle before and the cake batter extract flavor in this thing is legitimately unreal for something that took 20 minutes.
LorAnn Oils cake batter flavor, that's the one I use. Craft stores carry it if you don't want to wait on shipping.
Tried four other keto birthday cake chaffle recipes before this one. The others just tasted like vanilla waffles with frosting slapped on top. This one actually tastes like birthday cake. The difference? Cake batter extract. No idea how I overlooked that ingredient for so long. My daughter's birthday is next weekend and I finally have something I'm genuinely excited to serve.
That extract is what makes it. Without it you're just eating vanilla waffles with frosting. LorAnn cake batter is the one I use.
I genuinely thought a chaffle birthday cake was the most depressing idea I'd ever heard. Three tiny waffles stacked with frosting while everyone else eats real cake? Hard pass. But my daughter turned 10 last week and she's been doing keto with me for six months, so I caved and made it. The cake batter extract is doing something I cannot fully explain. It hits exactly like the yellow box cake batter I grew up licking off the beaters. We made the whole thing in maybe 22 minutes, she blew out candles on her little three-layer stack, and she was so proud of it that she teared up a little (she's 10, it's allowed). I had such embarrassingly low expectations going in, and I am so glad I was wrong.
Her blowing out candles on that little three-layer stack at 10. That's the whole point of this recipe. The cake batter extract is what makes it actually taste like birthday cake and not just vanilla waffles. Glad you caved.
This ranks top among my favorite keto desserts. I double the recipe and use a traditional waffle iron. It’s less work and there’s more for the freezer when I want something decadent. Swapped almond extract for the cake batter extract and added equal parts of almond and vanilla extracts to the frosting. Dynamite!! Thank you for creating this blue ribbon recipe.
The almond in the frosting is such a good call. I'm trying that next time. And yeah, the full waffle iron makes way more sense when you're batch cooking for the freezer.
I don't know why but mine is floppy (firmed up some as it cooled) and has no body to the cake part - nothing like in the picture. Just like every other cream cheese based chaffle I've tried. The taste is ok - but the texture is nothing like the picture on this post.
The texture should be like soft like other chaffles made with cream cheese. It should be the same as my other cream cheese based chaffles. If you watch the video you can see more of what it looks like. I have other chaffle cake recipes on my website with similar textures. It also may depend on how you are mixing the batter.
10/10 for sure. It taste like a real waffle. My teenage son loved it and he is not easy to please. So delicious. Thank you
Picky teenagers are the real test. The cake batter extract is what gets them, it doesn't read as keto at all.
FYI, Stoka is no longer in business. There are a few other sugar free sprinkle companies out there, but reviews are mixed and taste and texture are personal. Fantastic recipe. Just have to make sure the waffles are timed right so they don't get too dry.
Ugh, thanks for the heads up. I'll get the post updated. And yeah, they dry out fast if you go even a little too long. I pull mine at 3 minutes and let them sit.
Absolutely AMAZING and totally idiot proove. If you've never made a cake in your life you can't mess this up its so easy and quick to do. I've done a few of them, people always love the result and I love its so simple to make but great in taste.
Thanks for creating and sharing this recipe- a real life saver.
Ha, same reaction every time. The cake batter extract is what does it, people never guess it came out of a mini waffle maker.
Can't wait to try this for my birthday is the monk fruit the granulated with erythritol? Your recipes are the best
Thank you! Yes, I used granulated monkfruit blend with erythritol.
If I don't have monk fruit, what can I use to sweeten the chaffle with/ and what measurement would it be?
Thanks!

Would this recipe work in the dash mini bundt maker?
I don't have the mini bundt maker but I think it should work!
Yes!
Just to let everyone know. If you are missing that pancake or waffle Sunday breakfast well I am here to tell you that this Angel on earth has come to save us from our cravings!
I make chaffles weekly now! With choczero maple syrups they are exact like a regular old wheat flour waffle! Delicious!
