🍋 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
-
In a bowl, whisk powdered Keystone Pantry Allulose, lemon juice, and heavy cream until smooth.
-
Adjust thickness — add more powdered allulose for thicker glaze, or a touch more lemon juice for a thinner one.
-
Pour over the completely cooled cake, letting it drip down the sides.
-
Sprinkle lemon zest on top if desired.
