How to Make Flourless Lemon Zucchini Cake

Step 1: Prep

Preheat oven to 350°F (175°C). Line or grease an 8-inch round or square pan.

Step 2: Prepare Zucchini

Shred zucchini finely and squeeze out as much liquid as possible using a clean kitchen towel. This step is key for a non-soggy cake.

Step 3: Mix Batter

In a bowl, whisk eggs with honey (or sweetener), lemon juice, zest, and vanilla. Stir in almond flour, baking powder, salt, and zucchini until well combined.

Step 4: Bake

Pour batter into prepared pan. Bake for 25–30 minutes, until set in the center and lightly golden on top.

Step 5: Cool

Let cake cool completely before slicing or glazing.
