Bright Whole-Lemon Blender Cake with Lemon Glaze Tips, FAQ & printable recipe

Tips for success

For the best flavor, use a lemon that feels heavy for its size, as it will be juicier. If the lemon is very large, you may want to use just two-thirds of it to avoid overpowering the cake.

Always wash the lemon well to remove any wax or residue. The glaze should be thick but pourable; if it's too thick, add a drop more lemon juice; if too thin, whisk in a little more confectioners' sugar.

To get clean slices, chill the cake for about 30 minutes before slicing. This firms up the crumb and makes it easier to cut. Use a serrated knife and cut with a gentle sawing motion.

For a prettier presentation, dust the top with a little extra confectioners' sugar just before serving, or add a few thin lemon zest curls.

Variations

• Lemon Poppy Seed: Add 2 tablespoons of poppy seeds to the dry ingredients and fold them into the batter before baking. The poppy seeds add a subtle crunch and nutty flavor that pairs beautifully with the lemon.
• Lemon Blueberry: Gently fold 1 cup of fresh blueberries into the batter after combining the wet and dry ingredients. The berries will burst during baking, creating pockets of juicy sweetness. If using frozen berries, toss them in a little flour to prevent sinking.
• Lemon Rosemary: Add 1 tablespoon of finely chopped fresh rosemary to the blender with the wet ingredients. The herbal notes of rosemary complement the bright lemon flavor, making this a sophisticated adult dessert. Drizzle with honey before serving.
• Gluten-Free Lemon Cake: Substitute the all-purpose flour with a 1-to-1 gluten-free flour blend that contains xanthan gum. The batter will be slightly thicker, so you may need to add an extra tablespoon of milk. Bake as directed; the texture will be tender and moist.

Storage and make-ahead

Fridge

Refrigerate any leftover cake in an airtight container for up to 5 days. Bring to room temperature before serving to restore the tender crumb.

Freezer

Freeze the unglazed cake wrapped in plastic wrap and foil for up to 3 months. Thaw at room temperature, then glaze and serve.

Reheat

To reheat individual slices, microwave for 10-15 seconds or warm in a 300°F oven for 5 minutes. Serve warm with a scoop of ice cream.

Store the cake in an airtight container at room temperature for up to 3 days. The glaze will stay glossy, and the cake will remain moist. If the weather is very warm, you can refrigerate it, but bring it to room temperature before serving to soften the crumb. Freeze the cake for longer storage.

The cake can be baked a day ahead. Cool it completely, then wrap tightly in plastic wrap and store at room temperature. Glaze the cake just before serving to keep the top shiny.

The batter can also be made a few hours ahead and kept in the refrigerator, but blend it again briefly before baking to re-emulsify.

Serving ideas

The glaze adds a sweet-tart finish, while the crumb is tender and moist. For a more decadent dessert, serve with a dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream. The citrus flavor pairs beautifully with berries, so a handful of fresh raspberries on the side is lovely.

This cake is equally delicious at breakfast or brunch, alongside a glass of cold milk or a latte. The lemon flavor is refreshing and not too sweet, making it a versatile treat.

If you're serving it as a dinner party dessert, add a drizzle of warm lemon curd or a sprinkle of toasted coconut for extra texture. The cake is best enjoyed the day it's made, but it will keep well for a few days.

Bright Whole-Lemon Blender Cake with Lemon Glaze

Prep 10 minCook 45 minTotal 55 minServes 10

Ingredients

• 1 whole lemon, washed and cut into wedges
• 3 large eggs
• 1 cup vegetable oil
• 1 cup milk
• 1 cup granulated sugar
• 2 cups all-purpose flour
• 2 tsp baking powder
• 1/2 tsp salt
• 1 1/2 cups confectioners' sugar
• 3 tbsp fresh lemon juice

Instructions

1. Place the washed whole lemon wedges, eggs, oil, milk, and granulated sugar in a blender. Blend on high for 2 minutes until the mixture is completely silky and smooth, with no visible pieces of lemon. The liquid will be pale yellow and slightly frothy.
2. In a separate mixing bowl, whisk together the all-purpose flour, baking powder, and salt. Make sure the baking powder is evenly distributed so the cake rises evenly.
3. Pour the blended lemon mixture into the bowl with the dry ingredients. Gently fold with a spatula or whisk just until no streaks of flour remain. The batter will be thin and pourable, similar to a pancake batter.
4. Pour the batter into a greased 9x5-inch loaf pan. Bake at 350°F (175°C) for 45 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean. The cake will be domed and fragrant.
5. While the cake bakes, whisk together the confectioners' sugar and fresh lemon juice in a small bowl until smooth. The glaze should be thick but pourable; add more lemon juice a teaspoon at a time if needed.
6. As soon as the cake comes out of the oven, pour the glaze over the hot crust. The glaze will melt into the warm cake, creating a translucent, shiny finish. Let the cake cool in the pan for 15 minutes before transferring to a wire rack.
7. Let the cake cool completely on a wire rack before slicing. Use a serrated knife to cut thick slices, revealing the moist, tender crumb with flecks of lemon zest and walnuts.
