Keto Lemon Pound Cake is the bright, moist dessert you make when you want something sweet but still low-carb. I first made this on a weekend when I was craving something citrusy but didn’t want to break keto and it instantly became a repeat bake in my kitchen. The fresh lemon flavor in both the cake and glaze makes this Keto Lemon Pound Cake taste bakery-level without the sugar.

This Keto Lemon Pound Cake is gluten-free, grain-free, sugar-free, and THM-S friendly. It’s rich like a classic pound cake but has that light lemon finish that keeps every bite refreshing instead of heavy.

Ingredient Notes & Smart Swaps

Almond flour gives this Keto Lemon Pound Cake a delicate crumb, while coconut flour absorbs excess fat so the texture stays balanced. Don’t replace them 1:1 they behave very differently.

Cream cheese is the secret ingredient that adds texture here. It gives Keto Lemon Pound Cake that slightly dense, silky structure pound cakes are known for.

How to Make Keto Lemon Pound Cake (Step-by-Step)

Step 1 — Prep

• Preheat oven to 325°F / 165°C. Line a loaf pan with parchment. Proper prep helps the Keto Lemon Pound Cake release cleanly.

Step 2 — Cream Base

• Beat butter and cream cheese until smooth and fluffy. Add sweetener and continue mixing until light. This step builds the base texture of the Keto Lemon Pound Cake.

Step 3 — Add Eggs

• Add eggs one at a time. Mix fully after each addition. This prevents separation and keeps your Keto Lemon Pound Cake batter stable.

Step 4 — Add Lemon Flavor

Mix in lemon juice, lemon zest, and vanilla. The zest is where most of the Keto Lemon Pound Cake flavor lives. Don’t skip it.

Step 5 — Combine Dry Ingredients

• In another bowl mix almond flour, coconut flour, baking powder, and salt. Gradually add to wet mixture. Stir until thick and smooth.

Step 6 — Transfer to Pan

• Spread batter evenly in the loaf pan. Smooth the top so your Keto Lemon Pound Cake bakes evenly.

Step 7 — Bake

• Bake 55–65 minutes. Tent loosely with foil if top browns too fast. A toothpick should come out mostly clean when the Keto Lemon Pound Cake is done.
• Cool fully before glazing.

Lemon Glaze Instructions

Mix powdered sweetener with lemon juice and zest. Adjust thickness with cream or more lemon juice. Drizzle over cooled Keto Lemon Pound Cake and let it set.

Add extra zest if you love strong citrus flavor — it makes the Keto Lemon Pound Cake pop.

👨‍🍳 Pro Tips

• Use room temperature ingredients — better mixing, better texture
• Zest lemons before juicing (much easier)
• Don’t overbake — keto cakes dry faster
• Let it cool fully before slicing

Storage & Freezing Guide

Store your Keto Lemon Pound Cake in an airtight container at room temp for 2 days or refrigerated up to 5 days. Flavor actually deepens after resting.

To freeze: slice first, then freeze portions. Thaw on the counter texture stays excellent.
