Step-by-Step Instructions for Baking
Preparing the Zucchini for the Cake
Start by placing the shredded zucchini in a sieve and sprinkle with salt. Toss it gently and let it drain for one hour. Squeeze it thoroughly to remove excess moisture; this step ensures your cake remains light and fluffy.
Mixing the Cake Batter
Preheat your oven to 325°F (163°C) and grease two 9-inch round cake pans. In a medium bowl, mix the almond flour, coconut flour, whey protein powder, baking powder, and salt. In a large bowl, beat the softened butter and Swerve Sweetener until fluffy. Add the eggs one at a time, mixing well after each addition. Stir in the zucchini, lemon zest, and vanilla extract. Gradually add the dry mixture, then incorporate the lemon juice. If the batter feels too thick, add water one tablespoon at a time until it reaches a spreadable consistency. Gently fold in the blueberries before dividing the batter between the prepared pans.
Baking and Cooling Your Keto Cake
Bake the cakes for 30 to 40 minutes, or until they are golden brown and spring back when touched. Once baked, remove them from the oven and let them cool completely in the pans. Run a knife around the edges to loosen the cakes before transferring them to a wire rack.
Crafting the Creamy Lemon Frosting
For the frosting, beat the softened cream cheese and butter until smooth. Gradually add the powdered Swerve Sweetener, lemon zest, lemon juice, and heavy whipping cream. Mix until everything is well combined and creamy.
Assembling Your Beautiful Layer Cake
To assemble, place one cake layer on a serving platter and spread half of the frosting on top. Add the second layer and finish with the remaining frosting. For a final touch, garnish with fresh blueberries, making your cake not only scrumptious but visually appealing too!
Tips for a Perfect Keto Lemon Blueberry Cake
Zucchini Preparation is Key
Ensure you squeeze the zucchini very dry using your hands or a tea towel to avoid a soggy cake. This simple step can significantly impact the texture of your dessert.
The Importance of Whey Protein Powder
Whey protein powder is crucial for the rise of the cake. If you need a substitute, use egg white protein powder for similar results.
Achieving Smooth Frosting
Make sure your butter and cream cheese are well softened before mixing. If necessary, microwave the butter for about 10 seconds to soften it further. This will help you achieve a smooth, creamy frosting.
Maximizing Lemon Flavor
For an extra zing, consider using lemon extract in the cake instead of vanilla. Additionally, always opt for fresh lemon zest for the most vibrant flavor.
Substitutions and Storage
Ingredient Substitutions
If you need to make substitutions, egg white protein powder works well in place of whey protein. You can also swap lemon extract for vanilla extract to elevate the lemon flavor even more.
How to Store Your Keto Cake
Store any leftover keto lemon blueberry cake in an airtight container in the refrigerator. It will stay fresh for up to a week, but I doubt it will last that long!
