How to Make Keto Mocha Walnut Cake

We have everything we need now, so let's get baking! Follow these simple steps to make a delicious cake from scratch.

Step 1: Preheat the Oven

Grease and line an 8-inch round cake pan with parchment paper, then preheat your oven to 350°F (175°C). This guarantees consistent baking and prevents the cake from sticking.

Step 2: Prepare Dry Ingredients

In a large mixing bowl, whisk together almond flour, unsweetened cocoa powder, instant espresso powder, baking powder, and salt. This will ensure that all your dry ingredients are well-mixed and ready for the wet ingredients.

Step 3: Mix Wet Ingredients

In a separate bowl, beat together eggs, unsweetened almond milk, melted coconut oil, erythritol, and vanilla extract until smooth and combined.

Step 4: Combine Wet and Dry Ingredients

Slowly add the wet ingredients into the dry ingredients while stirring to combine. Be sure to mix until you have a smooth batter with no lumps. If the batter seems a bit thick, you can add a splash more almond milk to loosen it up.

Step 5: Add Walnuts

Fold in the chopped walnuts for a nutty crunch that pairs perfectly with the rich mocha flavor.

Step 6: Bake the Cake

After the cake pan is ready, pour the batter into it and level it out. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean. Once done, allow the cake to cool completely before frosting.

Step 7: Prepare the Frosting

While the cake cools, make the cream cheese frosting. In a bowl, beat together the softened cream cheese and butter until smooth. Add the powdered erythritol, vanilla extract, and heavy cream, and continue beating until the frosting is fluffy and creamy.

Step 8: Frost the Cake

Spread the cream cheese icing on top of the cake after it has cooled fully. You can also pipe the frosting for a more decorative look.

Step 9: Serve and Enjoy!

Slice your keto mocha walnut cake, serve, and enjoy! Pair it with a hot cup of coffee for the ultimate mocha experience.
