Recipe Ingredients

For the Cake

• 2 cups Almond Flour
• 1/4 cup Coconut Flour
• 3/4 cup Granulated Erythritol
• 1 1/2 tsp Baking Powder
• 1/4 tsp Salt
• 4 large Eggs
• 1/2 cup Butter, softened
• 1/3 cup Sour Cream
• 1 tsp Vanilla Extract

For the Strawberry Swirl

• 1/2 cup Fresh Strawberries, finely chopped
• 1 tbsp Granulated Erythritol
• 1 tsp Lemon Juice

How To Make

Step 1

Preheat your oven to 325F and grease a 9×5-inch loaf pan, then line the bottom with parchment paper.

Step 2

Make the strawberry swirl by combining the finely chopped strawberries, granulated erythritol, and lemon juice in a small bowl. Mash with a fork until you have a chunky jam-like mixture. Set aside.

Step 3

Beat the softened butter and granulated erythritol together with an electric mixer on medium-high speed for 3 minutes until light and fluffy. Add the eggs one at a time, beating well after each. Mix in the sour cream and vanilla extract until smooth.

Step 4

In a separate bowl, whisk together the almond flour, coconut flour, baking powder, and salt. Gradually add the dry mixture to the wet, mixing on low speed until just combined into a thick batter.

Step 5

Pour two-thirds of the batter into the prepared loaf pan. Dollop the strawberry mixture in spoonfuls across the surface. Top with the remaining batter.

Use a butter stick or thin spatula to drag through the batter in a zigzag pattern to create a beautiful swirl. Don’t over-swirl or the pattern will disappear.

Step 6

Bake for 55 to 65 minutes until the top is golden and a toothpick inserted in the center comes out clean. If the top browns too quickly, tent loosely with foil after 40 minutes.

Step 7

Let the cake cool in the pan for 15 minutes, then turn it out onto a wire rack to cool completely before slicing.

Tips

Cream the Butter and Erythritol the Full 3 Minutes

Don’t rush the creaming step. Erythritol doesn’t dissolve the same way sugar does, so you really need those full 3 minutes on medium-high to break down the crystals and whip air into the butter.

If you cut this short, you’ll feel a gritty texture in the finished cake and it won’t rise as well. The mixture should look noticeably lighter in color and fluffy before you start adding eggs.

Bring Your Eggs to Room Temperature

Cold eggs straight from the fridge can cause the creamed butter to seize up and look curdled when you add them. That messes with the texture of the final cake.

Just pull the eggs out about 30 minutes before you start baking. If you forgot, place them in a bowl of warm water for 5-10 minutes and they’ll be ready.

Adding them one at a time and beating well after each one is also important here. It keeps the batter smooth and emulsified instead of lumpy.

Squeeze the Moisture Out of the Strawberries

After you mash the strawberries with the erythritol and lemon juice, let the mixture sit for a few minutes. You’ll notice some liquid pooling at the bottom of the bowl.

Give it a gentle press with the fork and drain off some of that extra liquid before you dollop it onto the batter. Too much moisture from the strawberries can create a soggy streak through the middle of your cake instead of a clean swirl.

Frequently Asked Questions

Can I use frozen strawberries instead of fresh?

You can, but make sure to thaw them completely first and drain off any extra liquid. Frozen strawberries release a lot more moisture than fresh ones, and too much liquid in the swirl can make the center of the cake soggy or prevent it from baking through properly.

After draining, pat them dry with a paper towel before mashing them up with the erythritol and lemon juice. The swirl won’t look quite as vibrant, but the flavor will still be great.
