Almost every weekend I bake these fluffy keto strawberry muffins — 3.3g net carbs each thanks to the almond flour, and my kids grab them straight off the cooling rack.
I started making these strawberry muffins because I needed a breakfast that could survive a backpack. Something I could bake on Sunday and grab all week without thinking about it. That was three years ago, and I still make them almost every weekend.
The base is simple: almond flour batter with melted butter, eggs, and heavy cream. What makes these work is that the strawberries get tossed with a little monkfruit sweetener first, which pulls out their juices and makes every bite taste like actual strawberry, not just muffin with pink spots. I tested this with and without that sweetener step, and the difference is noticeable. Without it, the fruit just sits there. With it, the strawberry flavor blooms through the whole muffin.
The texture lands somewhere between a traditional muffin and a quick bread. Dense enough to hold together in a bag, soft enough that the edges get a slight crispness when they come out of the oven. I like to swipe a little butter on top while they're still warm. My husband thinks that's overdoing it. I disagree.
What I appreciate about this recipe is how forgiving the batter is. I've accidentally doubled the cinnamon, forgotten the vanilla once, and used strawberries that were a day past their peak. Every batch still turned out. The almond flour base is sturdy enough that small variations don't wreck the result. That's not true for every baking recipe I've posted.
One thing to know about almond flour batter: it doesn't rise the way wheat flour does. If you fill your liners only halfway, you'll end up with flat little discs. Fill them right to the top. I learned this the hard way my first time and now I never underfill. You want to see batter at the rim before it goes in the oven.
The whole batch takes about 30 minutes from start to oven, and you get 24 mini muffins or 12 regular ones. I usually go with minis because they're easier to portion and my kids can grab two without me doing math on macros. Either size works, but the minis bake faster (10 minutes versus 14-16 for regular).
Using fresh or frozen strawberries
I use fresh strawberries most of the time, but frozen work just as well. If you’re using frozen, let them thaw for about 10 minutes, chop them small, and pat them dry with a paper towel. The excess moisture matters more than you’d think. If you skip the pat-dry step, the batter around the berries stays soggy and you’ll notice it when you bite in. I’ve done side-by-side batches comparing wet versus dry, and the patted-dry ones bake more evenly every time.
Which muffin tin to use
I make these in either a mini muffin tin or a regular muffin pan. Either way, use liners. I’ve tried greasing the pan with butter and coconut oil spray, and the batter still sticks.
Fill the liners all the way to the top. This batter doesn’t rise the way wheat flour does, so if you go halfway, you’ll get flat pucks instead of muffins. I fill mine right to the rim and get a nice gentle dome every time. If you want more baking projects, my keto bagels use the same fill-to-the-top approach.
How I store and meal prep these
I store these in an airtight container at room temperature and they stay good for about 5 days. The fridge works too, but the texture gets a little denser after a day or two. I actually prefer them at room temp.
For freezing, I put them in a freezer bag, push out as much air as I can, and they hold up for about 2 months. When I want one, I just pull it out the night before or toss it in my bag in the morning. By lunchtime, it’s thawed and ready. I do the same thing with my keto banana bread slices for the same grab-and-go reason.
How to make keto strawberry muffins
Toss the strawberries with a tablespoon of sweetener and set aside. This draws out their juices so you get real strawberry flavor in every bite, not just pink specks.
Whisk the dry ingredients (almond flour, baking powder, cinnamon) in a medium bowl.
Beat the wet ingredients (melted butter, sweetener, eggs, heavy cream, vanilla) in a large bowl.
Fold the dry into the wet until just combined. Stop the second you don't see dry streaks. Overmixing makes almond flour batter tough and gives you peaked tops instead of smooth domes.
Fold in the strawberries gently so they stay in chunks.
Fill your liners to the top and bake. This batter doesn't rise like wheat flour, so filling high is how you get a muffin top.
Key ingredients & substitutions
Almond flour: The base of these keto muffins. I've tested sunflower seed flour cup-for-cup and it works if you have a nut allergy. For coconut flour, use about 3/4 cup and add one extra egg, since coconut flour absorbs way more liquid.
Butter: Melted. For dairy-free, swap in melted coconut oil at the same amount.
Eggs: Three eggs hold the batter together and give you that slightly domed top.
Heavy cream: Adds richness. I'd use coconut cream as a dairy-free alternative. Full-fat Greek yogurt works too (reader Darlene asked about this, and I think either would be fine).
In a small bowl, combine strawberries with 1 tablespoon monkfruit sweetener. Set aside.

Frequently Asked Questions
Are strawberries keto?
Yes, and they're one of my favorite fruits to bake with on keto. A 2/3 cup of chopped strawberries adds only about 6 net carbs to the entire batch, which spreads out to barely anything per muffin. I use strawberries more than any other fruit in my baking because they hold their shape, taste great, and keep the carbs low.
Can I substitute coconut flour for almond flour?
I haven't tested coconut flour in this exact recipe, but based on my experience with other muffin recipes, I'd start with 3/4 cup coconut flour and add one extra egg. Coconut flour absorbs significantly more liquid than almond flour, so the ratio isn't 1:1. If the batter looks too thick, add a splash more heavy cream. I'd love to hear how it turns out if you try it.
How do I make these dairy-free?
I swap the melted butter for melted coconut oil (same amount) and use coconut cream instead of heavy cream. The coconut oil gives a slightly different flavor, but it's subtle. My family can barely tell the difference when I make the swap.
Can I use almond milk or Greek yogurt instead of heavy cream?
I haven't tried almond milk in these, but my instinct is that it's too thin and you'd lose some of the richness. Full-fat Greek yogurt would be a better swap. Use the same amount and mix it in with the wet ingredients. The batter might be slightly thicker, but the muffins should still bake up fine. This is one of those things I plan to test soon.
How many net carbs are in each muffin?
It depends on the size. My mini muffins come out to about 1.5-2g net carbs each, and the regular-sized ones are around 3-4g. I calculate based on the whole batch using 2/3 cup strawberries and monkfruit sweetener (which has zero net carbs). These are one of the lightest muffin recipes I make.
Can I mix in other berries?
Reader Allison tried a mix of strawberries and blueberries and said they came out great, and I believe it. I'd keep the total fruit amount the same (2/3 cup) and chop everything to a similar size so it distributes evenly. Raspberries would work too, though they break down more during mixing. I'd fold them in very gently.
How do I keep these muffins moist?
The heavy cream and butter are doing most of the work here. I don't skimp on either. The other trick is not overbaking. I pull my regular-sized muffins at 14-16 minutes, even if they look barely set on top. They firm up as they cool. If you leave them in until they look fully done in the oven, they'll be dry by the time they hit room temperature. I've made that mistake more than once.
I’m the person who usually talks people out of keto muffin recipes, so I made these half expecting to prove myself right. The almond flour bakes up with a real crumb (not that dense sponge I keep warning about), and the strawberries being actual fruit instead of flavoring is the part I wasn’t prepared for.
Figured out that premixing the dry ingredients in a bigger jar saves me every week. I make three batches worth at once and just measure out what I need on Sunday, so all that’s left is mixing in the wet stuff and prepping the berries. About 18 minutes to 36 muffins cooling on the rack. Two in a container each morning and breakfast is handled for the week.
Three batches of dry mix in one jar is smart. I’ve done two ahead but never three, and now I’m wondering why I stopped short. The one thing I’d watch is the baking powder going a little flat if the jar sits more than a couple of weeks, so give it a shake before you scoop. Thank you for sharing that with me, I’m stealing the Sunday part of this for next month.
3.3 net carbs per muffin and no eggy sponge texture, which is the thing that’s always wrecked almond flour baked goods for me, so I’m paying attention. The butter step here is doing something I haven’t seen in a quick bread before (I’ve made enough shortbread to recognize the technique), creaming into the sweetener first instead of just melting into wet ingredients, and the crumb set up completely differently because of it. Used Kerrygold, probably matters, the extra fat in grass-fed butter tends to shift things in almond flour baking. Heavy cream over almond milk: the lift is real, and the texture shreds when you break one open instead of pressing flat. Which is not nothing. Four stars because the top goes a little dry at exactly 22 minutes, but that’s a timing note not a recipe problem.
Pull these at 14-16 minutes. Mine still look barely set on top when they come out, they finish on the rack. Twenty-two minutes is what’s giving you the dry top.
Left a batch cooling Saturday morning and came back to find my husband reading the nutrition label on my phone. Completely unprompted. This is a man who genuinely does not care about macros, baked goods are baked goods, end of conversation. But apparently eating a muffin that actually tastes like strawberries and finding out it’s 3.3 net carbs will make him do math he’s never done before. He wanted to know if I could freeze them.
Swapped the cinnamon into the strawberry step instead of the dry mix on batch five and the smell when these come out of the oven now? Completely different.
They baked up soft and the almond flour kept them from feeling heavy, but I’d go a touch higher on sweetener next time since spring strawberries aren’t very sweet yet and the berry flavor was pretty mild for me.
Tip for anyone whose muffins keep sticking to paper liners: silicone cups. The almond flour batter releases completely clean, and you actually get a slightly crisp bottom crust instead of losing half of it to the paper. Four batches in and this is the only way I’m making them now.
Silicone is so much better for almond flour batters. Paper just wicks the fat right out and takes the bottom with it. That crisp crust you’re getting is what these are actually supposed to have.
Usually for every cup of almond flour, you want to add 1/2 cup of lupin flour. I haven’t tried using lupin flour, but if I did, I would start with 1 1/4 cups lupin flour and see how the consistency of the batter is.
I’ve been making the blueberry muffins that use lemon and saw this recipe and decided to try with blueberries. Came out really good. I’ll use this one now, I like it much better and it’s less work. I don’t use paper liners as I find I lose a lot of the muffin. I just wipe the tins with butter.
Paper liners and almond flour muffins don’t mix. I lose half the muffin every time, which is why I’ve been greasing the tins instead. Glad the blueberries worked.
