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

Tips for success

For the most intense lemon flavor, use a ripe, fragrant lemon. If your lemon is thick-skinned, you may need to blend a little longer to break down the pith. If you prefer a less bitter cake, remove the seeds and trim the very ends of the lemon.

The pith is what gives the cake its moistness, so don't peel it off. For an extra burst of lemon, add a teaspoon of lemon extract to the blender along with the other wet ingredients.

When measuring flour, spoon it into the measuring cup and level with a knife rather than scooping, which packs the flour and can make the cake dry. If your oven runs hot, reduce the temperature to 325°F (165°C) and bake for 50-55 minutes.

Let the cake cool completely before glazing; a warm cake will absorb the glaze and lose its glossy finish. Store the cake loosely covered at room temperature for up to 3 days.

Variations

• Lemon Poppy Seed: Fold 1/4 cup poppy seeds into the batter before baking for a classic lemon-poppy seed loaf. The poppy seeds add a pleasant crunch and nutty flavor that pairs well with the lemon glaze.
• Olive Oil Version: Replace the neutral oil with extra-virgin olive oil for a fruity, savory note. Use a mild olive oil to avoid overpowering the lemon. The cake will be slightly more dense but still moist.
• Gluten-Free: Use a 1:1 gluten-free baking flour blend in place of all-purpose flour. Make sure the blend contains xanthan gum or another binder. The cake may be slightly more crumbly, so handle gently.
• Orange Twist: Swap the whole lemon for a whole small orange and use orange juice in the glaze. The flavor will be sweeter and less tart, with a lovely citrus aroma. Reduce the sugar to 3/4 cup if you prefer a less sweet cake.

Storage and make-ahead

Fridge

Store unglazed cake in the refrigerator for up to 5 days, wrapped tightly in plastic wrap. Bring to room temperature before glazing or serving.

Freezer

Freeze unglazed cake, tightly wrapped, for up to 2 months. Thaw overnight in the refrigerator, then bring to room temperature before glazing.

Reheat

To refresh slices, warm in a 300°F oven for 5-8 minutes. The glaze will soften but still taste delicious.

Store the glazed cake in an airtight container at room temperature for up to 3 days. If the weather is humid, the glaze may become sticky; that's fine. For longer storage, wrap the unglazed cake tightly in plastic wrap and keep in the refrigerator for up to 5 days.

Bring to room temperature before serving. If you've already glazed the cake, it's best to eat it within 2 days, as the glaze can soften the top crust.

You can make the cake a day ahead and glaze it the next morning. Bake and cool the cake completely, then wrap it tightly in plastic wrap and store at room temperature. When ready to serve, whisk together the glaze and pour it over the cake.

The glaze is best made fresh, but you can also make it ahead and store in a sealed container for up to 2 days; whisk before using. The cake itself freezes well for up to 2 months.

Serving ideas

Serve this cake as a dessert with a dollop of whipped cream or a scoop of vanilla ice cream. The bright lemon flavor pairs beautifully with fresh berries, especially raspberries or blueberries. For a brunch spread, cut thick slices and serve alongside coffee or tea. The glaze adds a sweet-tart finish that contrasts with the moist, tender crumb.

For a more elegant presentation, dust the top with a little extra confectioners' sugar just before serving, or garnish with a few thin lemon slices. The cake is sturdy enough to transport, making it a great choice for picnics or potlucks. It's also delicious on its own, with no accompaniments needed. Slice with a serrated knife for clean edges.

Bright Whole-Lemon Blender Cake with Glossy Glaze

Prep 15 minCook 45 minTotal 1 hServes 10

Ingredients

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

Instructions

1. Place the washed whole lemon wedges, eggs, oil, milk, and sugar in a blender. Blend on high for 2 minutes until the mixture is completely silky and smooth, with no visible pieces of lemon peel or pith. The liquid will look pale and slightly frothy.
2. In a large mixing bowl, whisk together the all-purpose flour, baking powder, and salt until well combined. Set aside while the blender finishes.
3. Pour the blended lemon mixture into the bowl with the dry ingredients. Gently fold with a spatula or whisk until just combined, being careful not to overmix. The batter will be thin and pourable.
4. Preheat the oven to 350°F (175°C). Pour the batter into a greased and floured 9x5-inch loaf pan. Bake for 45 minutes, until the top is deeply golden and domed, and a toothpick inserted into the center comes out clean or with a few moist crumbs.
5. Remove the cake from the oven and let it cool in the pan on a wire rack for 10 minutes. Then carefully turn it out onto the rack to cool completely before glazing.
6. In a small bowl, whisk together the confectioners' sugar and fresh lemon juice until smooth. The glaze should be thick but pourable, adding more juice a teaspoon at a time if needed.
7. Pour the glaze over the completely cooled cake, letting it drip down the sides and over the top. Slice with a serrated knife to serve.
