🧾 Ingredients

For the Cake

• 2 cups almond flour

• ¼ cup coconut flour

• 1½ teaspoons baking powder

• ¼ teaspoon salt

• ½ cup unsalted butter, softened

• ¾ cup granular sweetener (like monk fruit, erythritol, or allulose)

• 4 large eggs, room temperature

• ¼ cup sour cream or Greek yogurt

• ⅓ cup unsweetened almond milk

• 2 tablespoons fresh lemon juice

• 1 tablespoon finely grated lemon zest

• 1 teaspoon vanilla extract

• ½ teaspoon lemon extract (optional, for an extra pop of lemon)

For the Lemon Glaze

• ¼ cup powdered low-carb sweetener

• 1–2 tablespoons fresh lemon juice

• ½ teaspoon lemon zest

👩‍🍳 Instructions

1. Prepare the oven and pan
Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan and line it with parchment paper so the cake lifts out easily.

2. Combine dry ingredients
In a medium mixing bowl, whisk together the almond flour, coconut flour, baking powder, and salt. This ensures the flours blend evenly and the cake rises properly.

3. Cream butter and sweetener
In a large bowl, use a hand mixer to beat the softened butter and sweetener together until light and fluffy — about 2 minutes. This step creates air pockets that give your pound cake a delicate crumb.

4. Add eggs and flavorings
Beat in the eggs one at a time, then mix in the sour cream, almond milk, lemon juice, lemon zest, vanilla, and (if using) lemon extract. The batter will become smooth and fragrant — the lemon scent alone is pure sunshine.

5. Mix the batter
Gradually add the dry ingredients to the wet ingredients and mix just until combined. The batter should be thick yet creamy and spreadable.

6. Bake to perfection
Pour the batter into the prepared loaf pan and smooth the top. Bake for 45–55 minutes, or until golden and a toothpick inserted in the center comes out clean. The edges should be slightly crisp, and the aroma of lemon and butter will fill the kitchen.

7. Cool before glazing
Allow the cake to cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely before adding the glaze.

8. Make the glaze
Whisk together the powdered sweetener, lemon juice, and zest until smooth. Drizzle the glaze over the cooled cake, letting it run down the sides in pretty ribbons.

9. Slice and enjoy
Cut into thick, buttery slices and serve. Each piece is moist, tender, and perfectly balanced between sweet and tangy — the essence of simple elegance.

🍽️ Serving Suggestions

Enjoy this Keto Lemon Pound Cake with a steaming cup of tea, an espresso, or even a glass of almond milk. For a special treat, top each slice with a dollop of whipped cream or a few fresh raspberries — their tartness complements the lemon beautifully.

This cake also makes a wonderful brunch centerpiece or a thoughtful homemade gift. It keeps well in the fridge for up to 5 days and can be frozen (unglazed) for up to 2 months — just thaw and glaze before serving.
