Keto Strawberry Crunch Cake

If you think keto desserts can’t compete with the real thing, this strawberry crunch cake might change your mind. It’s layered, frosted, and topped with crunchy strawberry bits that make it feel like a proper celebration cake.

Everything in this recipe is low carb and sugar free, but you really wouldn’t know it from the taste. The cake itself is moist and tender thanks to a mix of almond flour, eggs, butter, and sour cream.

The star of the show is the freeze-dried strawberries. They show up in the cake batter, in the frosting, and in the crunch topping. So you get strawberry flavor in every single layer.

I love that this cake doesn’t require anything complicated. You mix, bake, frost, and add the crunch. That’s basically it.

It’s the kind of dessert you can bring to a gathering and no one will even ask if it’s keto. They’ll just ask for seconds.

Recipe Ingredients

For the Cake

• 2 cups Almond Flour
• 1/3 cup Coconut Flour
• 3/4 cup Granulated Erythritol
• 1 1/2 tsp Baking Powder
• 1/4 tsp Salt
• 5 large Eggs
• 1/2 cup Butter, melted
• 1/2 cup Sour Cream
• 1 tsp Vanilla Extract
• 1/4 cup Freeze-Dried Strawberries, crushed, plus more for crunch

For the Strawberry Cream Cheese Frosting

• 8 oz Cream Cheese, softened
• 1/4 cup Butter, softened
• 1/3 cup Powdered Erythritol
• 1/4 cup Freeze-Dried Strawberries, finely powdered
• 1 tsp Vanilla Extract

For the Crunch Topping

• 1/3 cup Freeze-Dried Strawberries, roughly crushed
• 2 tbsp Almond Flour
• 1 tbsp Melted Butter

How To Make

Step 1

Preheat the oven to 325F and grease two 8-inch round cake pans, lining the bottoms with parchment paper. Whisk together the almond flour, coconut flour, granulated erythritol, baking powder, and salt in a large bowl.

Step 2

In a separate bowl, whisk the eggs, melted butter, sour cream, and vanilla until smooth. Pour into the dry ingredients and stir until well combined. Gently fold in the crushed freeze-dried strawberries.

Divide the batter evenly between the two pans and smooth the tops. Bake for 28 to 32 minutes until a toothpick comes out clean. Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.

Step 3

Make the frosting by beating the cream cheese and softened butter together until fluffy, about 2 minutes. Add the powdered erythritol, powdered freeze-dried strawberries, and vanilla. Beat on medium-high for 2 minutes until light pink and creamy.

Step 4

Make the crunch topping by mixing the roughly crushed freeze-dried strawberries with the almond flour and melted butter. Spread on a parchment-lined tray and bake at 300F for 5 to 6 minutes until just crisp. Let cool and break into small crunchy bits.

Step 5

Place one cake layer on a serving plate and spread a thick layer of frosting on top. Place the second layer on top and frost the top and sides of the entire cake.

Step 6

Press the strawberry crunch topping generously over the top and gently around the sides of the cake. Refrigerate for at least 1 hour before slicing.

Tips

Don’t Skip Powdering the Erythritol for the Frosting

If your erythritol isn’t truly powdered, the frosting will feel gritty and grainy instead of smooth. You can make your own by blending regular granulated erythritol in a blender or spice grinder for about 30 seconds until it looks like powdered sugar.

Same goes for the freeze-dried strawberries that go into the frosting. They need to be ground into a fine powder, not just crushed. Any chunky pieces will make the frosting look lumpy and won’t blend into that smooth pink color you’re going for.

Let the Cake Cool Completely Before Frosting

Almond flour cakes are more fragile than regular cakes, and this one is no exception. If the layers are even slightly warm when you frost them, the cream cheese frosting will melt and slide right off.

Give the layers a full hour on the wire rack, or even pop them in the fridge for 20 minutes after they’ve cooled to room temperature. Cold layers are much easier to frost without tearing or crumbling apart.

Watch the Crunch Topping Closely in the Oven

The crunch topping goes from perfectly golden to burnt in about one minute. Set a timer for 5 minutes and check it. You want it just barely crisp, not dark brown.

Once it comes out, it will crisp up even more as it cools. If it still feels a little soft when you pull it out of the oven, that’s fine. Let it cool fully on the tray before you break it apart.

Frequently Asked Questions

Can I use fresh strawberries instead of freeze-dried?

Fresh strawberries won’t work as a substitute here because they contain a lot of moisture, which can make the cake soggy and change the texture completely. Freeze-dried strawberries are key because they add intense strawberry flavor without adding any extra liquid.

They also give the frosting that beautiful pink color and create the signature crunch topping, which you just can’t replicate with fresh berries.
