A spongy, tender cake made from FRESH strawberries and topped with a creamy strawberry frosting.
Pretty in pink, this strawberry cake is bursting with flavor. That’s because it uses fresh strawberries in both the cake and the cream cheese frosting.
Homemade cakes from scratch (like my favorited carrot cake or strawberry shortcake) don’t take a ton of effort. You basically dump in the gluten-free flours, sugar free sweeteners, strawberry puree and a few other ingredients. Mix and bake!
Serve your slice with a scoop of homemade ice cream or more strawberries (even better if they’re in season). This fresh, moist cake makes for a perfect summertime treat but you can enjoy it anytime of year, especially if strawberry is your favorite flavor!
How to make this strawberry cake
- Roast fresh strawberries in the oven with sugar free sweetener and a pinch of salt.
- Puree roasted strawberries in a food processer.
- Whisk together dry ingredients – almond flour, coconut flour, baking powder, salt.
- Cream together wet ingredients – whip the butter until fluffy, Add in sweetener, eggs, ¼ cup reserved strawberry puree and vanilla.
- Complete the cake batter by combining dry ingredients into the wet ingredients.
- Bake the cake.
- Make a creamy strawberry cream cheese frosting to top your cake!
Key ingredients
- Fresh strawberries – Ideally fresh is better since it has the most flavor (especially when strawberries are in season). Frozen strawberries can be used as long as you thaw them first.
- Low-carb flours – Almond flour and coconut flour are two of my favorite flours to use for keto baking. The combination of the two gives a texture and flavor similar to all-purpose flour.
- Sugar free sweetener – Use your favorite sugar free sweetener as long as it measures cup for cup with real sugar. Erythritol and monk fruit blended sweeteners like Lakanto work well. Truvia Sweet Complete is another favorite – it uses erythritol, chicory root fiber and stevia. Allulose sweetener can be used; however, it’s not as sweet as some of the other sugar free sweeteners, so you may need to add more.

Can I use all almond flour for this keto strawberry cake?
If you want to use only almond flour to make this cake, use 2 3/4 cup of almond flour.
I am allergic to nuts. What I can use in place of almond flour?
Sunflower seed flour is a perfect substitute for almond flour since it measures cup for cup with almond flour and is nut free.
Can I omit the cream cheese in the frosting?
Yes! If you don't want to make the cream cheese frosting, just make a strawberry buttercream frosting. Use 1 1/2 to 1 cup of softened butter to make the frosting.
ERROR ON INGREDIENT LIST!!
The ingredient list on the frosting calls for sugar free sweetener, just like on the cake batter mix. I bought all the ingredients at the store based on the ingredient list and had to go back out to buy POWDERED SUGAR- that’s frustrating so I’m letting others know.
I'm so sorry about that. I updated the recipe, but in the future, regular sweetener or powdered sweetener can be used for the frosting. :)
Where did you mix the sour cream to?
With the eggs. Sorry about that. The recipe is updated now.
This looks delicious! How long and at what temperature would you recommend baking this recipe as cupcakes?
I would still bake at the same temperature but they won't take as long to cook, so start with 15 minutes and go from there.
