Ingredients

  1. 4 large eggs
    • At room temperature for optimal blending and texture.
  2. 1 cup granulated erythritol
    • A low-carb sweetener that provides the necessary sweetness without impacting blood sugar levels.
  3. 1/2 cup unsalted butter
    • Melted and cooled. Adds richness and moisture to the cake.
  4. 1/2 cup almond flour
    • Provides a fine texture and subtle nutty flavor, serving as the primary dry ingredient.
  5. 1/4 cup lemon juice
    • Freshly squeezed for the best flavor. Adds a tangy zest to the cake.
  6. 2 tablespoons lemon zest
    • Finely grated from a fresh lemon to enhance the lemon flavor.
  7. 1 teaspoon baking powder
    • Helps the cake rise and become fluffy.
  8. 1/4 teaspoon sea salt
    • Balances the sweetness and enhances the overall flavor.
  9. 1/2 teaspoon vanilla extract
    • Adds depth and complements the lemon flavor.
  10. Optional: 1/4 cup powdered erythritol
    • For dusting on top of the cake for a touch of extra sweetness.

Instructions

  1. Preparation: Preheat your oven to 350°F (175°C). Grease an 8-inch round cake pan and line the bottom with parchment paper for easy removal.
  2. Prepare the Eggs: In a large mixing bowl, beat the eggs with an electric mixer or a whisk until they become frothy and slightly increased in volume. This process helps incorporate air into the batter for a light texture.
  3. Combine Wet Ingredients: In a separate bowl, whisk together the granulated erythritol, melted unsalted butter, lemon juice, lemon zest, and vanilla extract. Ensure the erythritol is fully dissolved into the liquid ingredients.
  4. Incorporate Dry Ingredients: In another bowl, sift together the almond flour, baking powder, and sea salt. This helps to remove any lumps and ensures even distribution of the leavening agents and salt.
  5. Mix Batter: Gradually add the dry ingredients to the wet ingredients, mixing gently until well combined. Avoid overmixing to ensure a tender cake texture.
  6. Fold in Egg Mixture: Carefully fold the beaten eggs into the batter, mixing gently to maintain the airiness. This step ensures that the cake rises properly during baking.
  7. Pour Batter: Pour the batter into the prepared cake pan, smoothing the top with a spatula to ensure an even surface.
  8. Bake: Place the cake pan in the preheated oven and bake for 25-30 minutes, or until the cake is golden brown and a toothpick inserted into the center comes out clean.
  9. Cool: Allow the cake to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely. This prevents the cake from becoming soggy and helps it set properly.
  10. Dust with Powdered Erythritol (Optional): Once the cake has cooled, lightly dust the top with powdered erythritol for an added touch of sweetness and a decorative finish.
  11. Serve: Slice and serve as desired. This cake pairs beautifully with a dollop of whipped cream or a few fresh berries, though it is equally delightful on its own.
  12. Storage: Store any leftover cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze for up to 3 months. Ensure the cake is well-wrapped to prevent freezer burn.

Useful Tips

  1. Egg Preparation: For best results, ensure your eggs are at room temperature. This helps them whip up more easily and incorporate better into the batter.
  2. Almond Flour: Be sure to use finely ground almond flour for a smooth texture. Coarser almond meal can result in a grainy cake.
  3. Lemon Juice: Fresh lemon juice is preferred for its bright, clean flavor. Avoid bottled lemon juice as it may contain preservatives that can affect the taste.
  4. Testing for Doneness: To ensure the cake is fully baked, insert a toothpick into the center. It should come out clean or with just a few moist crumbs.
  5. Serving Suggestions: Garnish with a sprinkle of fresh lemon zest or a few mint leaves for a decorative touch. Serve with a side of sugar-free vanilla ice cream for an indulgent treat.
  6. Make-Ahead: This cake can be made ahead of time and stored in the refrigerator. It can also be frozen and thawed before serving for convenience.
  7. Allergy Considerations: This recipe is naturally gluten-free and suitable for those on a keto diet. Ensure all ingredients, particularly the sweeteners, are checked for any allergens.
  8. Flavor Variations: For a different twist, consider adding a teaspoon of poppy seeds or a few drops of almond extract to the batter for added flavor.
