A delightful Keto Lemon Poppy Seed Cake paired with a luscious Blackberry Buttercream frosting, perfect for a low-carb, gluten-free dessert that bursts with citrus and berry flavors.


Ingredients

Scale

Cake

  • 2 cups almond flour
  • 1/4 cup poppy seeds
  • 1/2 cup erythritol
  • 1/2 cup unsalted butter, softened
  • 4 large eggs
  • 1/2 cup unsweetened almond milk
  • 1/4 cup lemon juice
  • 1 tablespoon lemon zest
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda

Blackberry Buttercream Frosting

  • 1/2 cup unsalted butter, softened
  • 1/4 cup blackberry puree
  • 1/4 cup erythritol


Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure it is ready for baking the cake evenly.
  2. Mix Dry Ingredients: In a bowl, combine almond flour, poppy seeds, erythritol, baking powder, and baking soda thoroughly to distribute all dry ingredients evenly.
  3. Prepare Wet Ingredients: In a separate bowl, beat the softened butter with eggs until smooth and creamy. Then add unsweetened almond milk, lemon juice, and lemon zest, mixing well to combine the flavors.
  4. Combine Ingredients: Gradually mix the wet ingredients into the dry ingredients, stirring until you achieve a smooth, well-combined batter.
  5. Pour and Bake: Grease a cake pan and pour the batter into it. Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
  6. Cool the Cake: Remove the cake from the oven and allow it to cool completely in the pan before applying the frosting.
  7. Prepare Frosting: In a bowl, beat the softened butter with blackberry puree and erythritol until creamy and smooth to create a flavorful buttercream.
  8. Frost the Cake: Spread the blackberry buttercream evenly over the cooled cake, then slice and serve.

Notes

  • Make sure the unsalted butter is softened to room temperature for easier mixing.
  • Use fresh lemon juice and zest for the best citrus flavor.
  • Allow the cake to cool completely before frosting to prevent melting.
  • Blackberry puree can be made by blending fresh or frozen blackberries and straining out seeds if desired.
  • This cake is ideal for those following a keto or gluten-free diet.
