🍋 Keto Lemon Pound Cake with Thick Glaze

Bright, tangy, and indulgent — this lemon pound cake has all the richness of the classic, but without the sugar or carbs that cause a blood sugar spike.
With a tender crumb from almond flour, a natural sweetness from Keystone Pantry Allulose, and a zingy lemon glaze, it’s the perfect afternoon treat or dessert for lemon lovers.


🛒 Ingredients & Their Purpose

For the Cake

  • 2 cups almond flour – The base of most keto cakes; low in carbs and naturally rich in healthy fats. Almond flour provides a moist, tender texture similar to traditional pound cake without the starches in wheat flour.

  • 1/4 cup coconut flour – Absorbs extra moisture and helps prevent a dense, greasy texture. Also adds fiber.

  • 1 1/2 tsp baking powder – Gives the cake lift and lightness.

  • 1/2 tsp baking soda – Works with the acid from lemon juice to boost rise and tenderness.

  • 1/4 tsp salt – Balances sweetness and enhances all the flavors.

  • 1 cup unsalted butter, softened – The heart of any pound cake. Butter adds richness, flavor, and that classic melt-in-your-mouth feel.

  • 1 1/4 cups Keystone Pantry Allulose – A keto-friendly sweetener with zero net carbs. Allulose bakes like sugar, browns beautifully, and doesn’t have a cooling aftertaste.

  • 4 large eggs, room temperature – Provide structure, moisture, and help emulsify fat for a smooth batter.

  • 1/4 cup heavy cream – Adds richness, moisture, and a creamy texture.

  • 1/4 cup fresh lemon juice – Gives bright citrus flavor and works with baking soda to create a lighter crumb.

  • 1 tbsp lemon zest – Intensifies the lemony aroma and flavor without adding extra liquid.

  • 1 tsp pure vanilla extract – Rounds out the flavors and softens the sharpness of lemon.

For the Thick Glaze

  • 1 1/2 cups powdered Keystone Pantry Allulose – Acts as the base for the glaze, dissolving into a silky texture without adding carbs.

  • 2–3 tbsp fresh lemon juice – Provides tartness and moisture for the glaze.

  • 1 tbsp heavy cream – Makes the glaze thicker and creamier, so it clings well to the cake.

  • 1/2 tsp lemon zest (optional) – Adds extra citrus punch for presentation and flavor.


🥣 Step-by-Step Instructions

1. Prepare Your Baking Pan

  • Preheat oven to 325°F (163°C).

  • Grease and line a 9×5-inch loaf pan with parchment paper for easy removal.

2. Mix the Dry Ingredients

  • In a medium bowl, whisk together almond flour, coconut flour, baking powder, baking soda, and salt.

  • Set aside — this keeps the leavening evenly distributed.

3. Cream Butter & Sweetener

  • In a large mixing bowl, beat the softened butter and Keystone Pantry Allulose for 3–4 minutes until pale and fluffy.

  • This step incorporates air for a lighter cake.

4. Add Eggs One at a Time

  • Beat in the eggs one at a time, mixing well after each addition.

  • Scrape down the sides to ensure even mixing.

5. Add Flavor & Moisture

  • Mix in the heavy cream, lemon juice, lemon zest, and vanilla extract until smooth.

6. Combine Wet & Dry

  • Add the dry ingredients into the wet mixture in two parts, mixing just until combined.

  • Do not overmix — almond flour can become dense if overworked.

7. Bake

  • Pour batter into the prepared loaf pan and smooth the top.

  • Bake for 55–65 minutes, or until a toothpick comes out clean.

  • Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.


🍋 Making the Thick Lemon Glaze

  1. In a bowl, whisk powdered Keystone Pantry Allulose, lemon juice, and heavy cream until smooth.

  2. Adjust thickness — add more powdered allulose for thicker glaze, or a touch more lemon juice for a thinner one.

  3. Pour over the completely cooled cake, letting it drip down the sides.

  4. Sprinkle lemon zest on top if desired.
