Moistest Whole-Lemon Cake with Tart Glaze

One whole lemon—peel, pith, and all—goes straight into the blender, turning this cake into the most fragrant, moist loaf you'll ever bake.

The natural oils in the peel infuse every crumb with bright citrus, while the pith adds tenderness without any bitterness. A tart powdered-sugar glaze seals in the moisture and adds a crackly finish. This is the cake that makes people ask for the recipe.

This whole-lemon cake is a game-changer for citrus lovers. Instead of zesting and juicing, you simply chop a fresh lemon, remove the seeds, and blend it with the wet ingredients.

The result is a deeply flavored, incredibly moist loaf that stays tender for days. The glaze, made with just powdered sugar and lemon juice, adds a tangy contrast that makes each slice irresistible.

Ingredients

Why this recipe works

Blending the whole lemon is the secret to this cake's extraordinary moisture and flavor. The lemon's natural oils, which live in the peel, are released during blending, infusing the batter with intense citrus aroma.

The pith, often discarded, is rich in pectin, which helps retain moisture and creates a tender, fine crumb. This method also eliminates the need for zesting and juicing separately, simplifying the process while maximizing taste.

The ratio of wet to dry ingredients is carefully calibrated. The eggs, oil, and milk provide richness and structure, while the blended lemon adds even more moisture.

Baking at a moderate temperature ensures the cake rises evenly and cooks through without drying out. The result is a loaf that is golden on the outside, soft and springy on the inside, and bursting with lemon flavor in every bite.

Notes and substitutions

Use a fresh, firm lemon with bright, smooth skin. Wash it thoroughly to remove any wax or residue. Remove all seeds before blending, as they can add bitterness. If you prefer a milder lemon flavor, you can remove the white pith, but the video shows using the whole lemon for maximum moisture and taste.

The baking powder and vanilla sugar are essential for lift and flavor. If you don't have vanilla sugar, substitute 1 1/2 teaspoons of vanilla extract. The glaze is simple but crucial: it adds sweetness and a beautiful sheen. For a thicker glaze, let it sit for a minute before pouring; for a thinner one, add a few drops of lemon juice.
