Keto trifle with layers of almond flour shortcake, billowy real-lemon whipped cream, and juicy fresh berries at 5.4g net carbs. It's my summer potluck go-to, and no one at the backyard party can tell it's low carb.
I started making this layered berry dessert for Fourth of July about five years ago, and it's become the one dish people ask me to bring to every summer gathering. What makes it work is real lemon whipped cream, not cream cheese dressed up to look like whipped cream. Most low carb trifle recipes use sweetened cream cheese as the filling, and you can taste the difference immediately. The lemon zest and juice cut right through the richness and make the whole thing taste like an actual dessert, not a substitute.
The base is an almond flour shortcake that I split between two 8-inch pans. I've tested this against store-bought cake mixes and the homemade version holds its structure better than anything else I've tried. The almond flour firms up as it sits in the fridge, so the layers are more defined after a few hours than when you first assemble. Multiple readers have told me they expected the layers to fall apart and were surprised when they didn't. Every regular trifle I've made with traditional cake eventually turns to soggy mush. This one holds.
Between the shortcake and whipped cream, I add a quick stovetop strawberry sauce and layers of fresh berries (raspberries, blackberries, blueberries, strawberries, whatever combination looks best at the store that week). The berry layer is what gets people every time. A reader told me her daughter asked to save the piece with more berries before she even sat down, which is exactly the kind of reaction that tells me a recipe is working. If you want a simpler version of the shortcake base, my keto strawberry shortcake uses the same almond flour recipe. And if chocolate is more your speed, my keto chocolate trifle goes in a completely different direction with cocoa and chocolate shavings.
What I love about this keto trifle is that it feeds a crowd without any last-minute scramble. I make each component separately (the shortcake, strawberry sauce, and lemon whipped cream can all be made a full day ahead), then assemble everything in a deep clear glass bowl right before people arrive. The assembled version improves after 6-8 hours in the fridge because the cake soaks up some of the lemon cream and takes on a poke-cake texture that I actually prefer to freshly assembled. Just hold the fresh berries until you serve so they stay bright and firm.
For more summer desserts that travel well, my berry bundt cake is another crowd favorite that I bring to neighborhood cookouts.
Almond flour: If you have a nut allergy, sunflower seed flour measures cup for cup and works as a direct swap. I haven’t tested coconut flour in this specific recipe, but 1 cup is a reasonable starting point if you want to experiment.
Butter: Melted coconut oil works here. I’ve used both and the finished shortcake tastes the same to me.
Sour cream: This is here to mellow out the egg flavor in the cake. Yogurt, buttermilk, or cream cheese all do the same job. I grab whatever I have open in the fridge.
Heavy whipping cream: For a dairy-free version, use almond milk or coconut milk in the cake batter. For the whipped cream layer, coconut cream whips up well and holds. You could also use a sugar-free pudding mix, but the lemon whipped cream is what makes this recipe stand out, so I’d stick with the real thing if you can.
If you want a berry dessert without the layered assembly, my strawberry cake is a simpler option with the same summer flavors. For a chocolate version, I mix 1/4 cup of unsweetened cocoa powder into the cake batter and it works well against the berries and lemon cream.
Shortcuts when you're short on time
If you don’t want to make every component from scratch, here are the shortcuts I actually use.
Use a boxed cake mix. Duncan Hines makes a keto-friendly option, and Good Dee’s is another solid brand. You won’t find a box mix specifically for shortcake, but yellow or vanilla cake works fine. My chocolate cake recipe is another base option if you want to go that direction.
Use cookies instead of cake.HighKey vanilla wafers crumbled into each layer add crunch and save you from turning on the oven. I do this when I’m bringing dessert somewhere and don’t want to bake.
Skip the strawberry sauce. The sauce adds a nice syrupy layer between the cake and cream, but this holds up fine without it. I skip it about half the time when I’m in a rush before a party.
Make-ahead and storage
This is a make-ahead dessert, which is half the reason I keep coming back to it for gatherings.
Components separately: I make the shortcake, strawberry sauce, and lemon whipped cream up to a full day before serving. Store each in the fridge in separate containers. The shortcake can sit wrapped at room temperature if your fridge is packed.
Assembled keto trifle: You can build this 6-8 hours before serving and it only gets better. The cake soaks up some of the lemon cream and takes on a texture similar to a poke cake, which I actually prefer to freshly assembled. It holds well for 1-2 days in the fridge. After about 2 days assembled, it shifts toward a pudding consistency, which is past its peak for me. Add the fresh berries right before serving so they stay bright and firm instead of bleeding into the cream.
For smaller gatherings, individual jars or cups assembled the morning of a party look impressive and let guests grab their own portions.
How to assemble this dessert
I break this into three components and make them in whatever order fits my schedule.
Bake the almond flour shortcake. Two 8-inch pans, 18-20 minutes at 350. Let it cool completely before cutting into bite-sized cubes. Warm cake crumbles.
Make the strawberry sauce. Fresh strawberries and sweetener in a saucepan until the berries break down, then puree smooth. About 10 minutes start to finish.
Whip the lemon cream. Heavy cream with sweetener, then add the lemon zest and juice once the cream starts to thicken and beat to stiff peaks. Start with less zest than you think you need and taste from there. Too much pushes it from bright to bitter.
Layer in a clear glass bowl. Whipped cream, cake cubes, strawberry drizzle, fresh berries. Repeat. End with whipped cream and a scatter of berries on top.
For a grab-and-go version, layer individual portions in mason jars, clear plastic cups, or small tumblers. The full recipe fills 12-16 individual portions, and they're easier to transport than a big glass bowl. My strawberry shortcake kebabs use the same low carb shortcake in a fun party format.
Preheat oven to 350 degrees. Spray two 8 inch cake pans with cooking spray and place a round sheet of parchment paper on the bottom of each pan. Set aside.

Frequently Asked Questions
How do I keep the whipped cream from deflating overnight?
I beat mine to stiff peaks (not just soft peaks) and it holds overnight in the fridge without any stabilizer. If you want extra insurance, add 1 tablespoon of cream cheese while beating. I've done it both ways and the flavor difference is undetectable, but the cream cheese version sets up a bit firmer.
Can I use frozen berries instead of fresh?
I use frozen berries in the strawberry sauce all the time because they break down faster and release more juice. For the fresh berry layers, frozen works in a pinch but they release moisture as they thaw, which can make the layers watery. If you go frozen for the layers, pat them dry with a paper towel and add them right before serving.
How do I lower the net carbs per serving?
Each 3/4 cup serving is 5.4g net carbs as written. The berries are the biggest carb source, so to trim that number I go heavier on blackberries and raspberries, which are lower in sugar per cup, and lighter on blueberries. Since scoop sizes vary with a layered dessert, I plug my exact portions into MyFitnessPal when I want a precise count.
What size trifle dish do I need?
The full recipe makes about 15 cups (20 servings at 3/4 cup each), so I use a large pedestal trifle bowl of around 4 quarts with straight sides. Any deep clear glass bowl that size works and shows off the layers, which is the whole visual appeal. To make less, divide every ingredient by two, bake in a single 8-inch cake pan instead of two, and layer in a 2-quart bowl or individual cups.
My sister-in-law is dairy-free and I want to bring something to a potluck we’re both at next month. The whipped cream swap seems easy enough, but the sour cream in the shortcake is where I’m stuck. I’ve used coconut cream or dairy-free yogurt in almond flour cakes before. Sometimes it works fine, sometimes things go weirdly dense. I can’t tell from the ingredient list if it’s mostly there for moisture or doing something structural for the crumb. Would either work here, or is one better in an almond flour base specifically?
Nicole, frozen works great in the sauce layer, it breaks down faster and gives you more juice. The berry layers are where I’d be careful. Thaw and pat dry first or the moisture bleeds into the whipped cream.
Making this for my cousin’s graduation party next month, probably 40-50 people, so I’m thinking triple the recipe. The egg white step is what I’m nervous about, honestly. I’ve never whipped that volume of whites at once and feel like it could go sideways. Also debating whether to use more 8-inch pans or switch to bigger ones for the shortcake layers. Does bake time shift much when you scale up like that?
The lemon cream surprised me too the first time I made it. Stiff peaks lock in that texture, it holds through layering and overnight in the fridge no stabilizer needed. Nice work, Luz.
Tip for anyone bringing this to a cookout: assemble without the berries the night before and let it chill overnight. The shortcake soaks up just enough of the lemon cream that the layers set up firm and actually slice cleanly the next day. So much better for transporting than anything I’ve tried.
One thing I wish I’d known going in: get the shortcake layers completely cold before you try to assemble. Like, fridge cold. First time I rushed it and the lemon whipped cream just started migrating everywhere the second I put the berries on top. Baked the layers the night before on my second attempt and assembled in the morning, and the whole thing held together for four hours at a spring cookout. Also tried it with coconut cream instead of heavy cream in the whipped topping and the coconut note actually plays really nicely against the lemon.
Swapped lemon for lime zest and a squeeze of juice in the whipped cream. Immediately brighter. Used raspberries instead of a mixed berry blend and it went full key lime territory, which was perfect against the almond flour shortcake. Shortcake held up overnight with no sogginess. That part matters when you’re assembling ahead. Would add another two tablespoons of sweetener to the cake, but otherwise making this again.
Lime and raspberry together is kind of an obvious combo now that you say it. I keep the cake batter low on sweetener so the cream carries it, but two more tablespoons makes sense if you’re eating slices plain.
This brought back my mom’s summer trifle from every family reunion, and the lemon whipped cream layer is close enough to make me a little emotional, even if the shortcake texture is still a work in progress for me.
Those memories are tough to top. Shortcake texture is almost always an egg white issue. They need to reach actual stiff peaks before folding in, not just soft peaks.
I’ve made four different keto trifles and every single one uses cream cheese dressed up as whipped cream, so the actual lemon whipped cream here is the first thing that’s tasted like the real dessert.
Yeah, a couple hours is fine, keep it covered in the fridge. The cake soaks up some of the lemon cream as it sits, which I actually prefer to freshly assembled. Hold the berries until you serve.
I just made this trifle today. It was soooo good! I made it exactly as written. It was the perfect sweetness, it fed a crowd and everyone including the kids loved it! I will be making this regularly. Thank you for such an amazing recipe!
Ha, kids loving a keto dessert never gets old. The lemon whipped cream is usually what gets people. Try making it the night before next time, the layers hold better after a few hours in the fridge.
It makes an enourmous quantity as it is meant to feed a crowd. You can add the ingredients to a macro calculator like MyFitnessPal and divide by the number of servings you want to get from it.
