Whole Lemon Cake with Tangy Glaze Tips, FAQ & printable recipe

Tips for success

For the best flavor, use a fresh, unwaxed lemon if possible. If only waxed lemons are available, scrub them well under warm water before boiling.

The boiling time is crucial: 6 minutes is just right for a large lemon. If your lemon is smaller, reduce the time by a minute; if larger, add a minute. The lemon should be tender enough to pierce easily with a fork.

When blending the lemon mixture, make sure the blender is not too full; blend in batches if needed. The emulsion should be completely smooth before adding the dry ingredients.

When folding in the dried fruits, toss them with a teaspoon of flour first to prevent them from sinking to the bottom of the cake. This ensures an even distribution throughout the loaf.

Variations

• Lemon Poppy Seed: Stir 2 tablespoons of poppy seeds into the batter along with the dried fruits. The poppy seeds add a pleasant crunch and a nutty flavor that complements the lemon. Toast the seeds lightly in a dry pan for extra depth.
• Citrus Mix: Replace the lemon with an orange or a mix of half lemon and half orange. Boil and blend as directed. The flavor will be sweeter and less tart. Adjust the glaze by using orange juice instead of lemon juice.
• Nutty Crunch: Fold in 1/2 cup of chopped toasted walnuts or pecans along with the dried fruits. The nuts add a rich, buttery crunch that contrasts nicely with the soft crumb. Toast the nuts in a dry skillet over medium heat until fragrant, about 3 minutes.
• Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum. The texture will be slightly more delicate, so handle gently. Check that all other ingredients, including the baking powder, are gluten-free.

Storage and make-ahead

Fridge

Store in the refrigerator for up to 5 days in an airtight container. Bring to room temperature before serving for best flavor and texture.

Freezer

Freeze the unglazed cake for up to 3 months. Wrap tightly in plastic wrap and then foil. Thaw overnight in the refrigerator.

Reheat

Reheat individual slices in the microwave for 15-20 seconds or in a 300°F oven for 5-7 minutes until warmed through.

Store the whole lemon cake in an airtight container at room temperature for up to 3 days. The glaze may soften slightly but will still be delicious.

For longer storage, wrap the unglazed cake tightly in plastic wrap and refrigerate for up to 5 days. Let come to room temperature before serving, or warm slices briefly in the microwave or toaster.

The cake can be baked up to 2 days ahead. Cool completely, wrap in plastic wrap, and store at room temperature. The glaze can be made ahead and refrigerated in an airtight container for up to 1 week; stir well before using. For best results, glaze the cake on the day you plan to serve it.

Serving ideas

Serve this whole lemon cake as a dessert with a dollop of lightly sweetened whipped cream or a scoop of vanilla ice cream. The bright citrus flavor pairs beautifully with berries or a simple fruit compote.

For an afternoon tea, slice it thick and serve with a cup of Earl Grey or chamomile. The cake is also wonderful for brunch, offering a fragrant, moist alternative to muffins or scones.

To slice cleanly, use a serrated knife and wipe the blade between cuts. The glaze may crack slightly, which is part of its charm. If you prefer a more intense lemon flavor, you can add a teaspoon of lemon zest to the glaze. For an extra touch, garnish with a few thin lemon zest curls or a sprig of mint just before serving.

Whole Lemon Cake with Tangy Glaze

Prep 15 minCook 41 minTotal 56 minServes 10

Ingredients

• 1 large whole lemon
• 3 large eggs
• 180 g granulated sugar
• 70 ml vegetable oil
• 50 ml whole milk
• 250 g all-purpose flour
• 10 g baking powder
• 100 g mixed dried fruits (such as raisins, currants, chopped apricots)
• 1 tsp chilled butter, sliced thin
• 1 cup confectioners' sugar
• 2 tbsp fresh lemon juice

Instructions

1. Place the whole lemon in a medium saucepan and cover with water. Bring to a gentle boil and cook for 6 minutes, until the lemon is softened and the skin is tender. Drain and let cool slightly. Slice the lemon into quarters and remove any seeds with a paring knife. Transfer the lemon pieces to an electric blender. Add the eggs, granulated sugar, vegetable oil, and whole milk. Blend for 45 seconds, scraping down the sides as needed, until the mixture is ultra-smooth and creamy.
2. In a large bowl, whisk together the all-purpose flour and baking powder. Pour the lemon emulsion into the dry ingredients and whisk until just combined, being careful not to overmix. Gently fold in the mixed dried fruits with a spatula until evenly distributed.
3. Preheat the oven to 320°F (160°C) fan-forced (or 325°F/165°C conventional). Butter a 13.8x6-inch loaf pan and line with parchment paper, leaving overhang on the long sides. Pour the batter into the prepared pan and smooth the top. Place the thin slice of chilled butter down the center of the batter—this will help create the characteristic crack along the top as the cake bakes.
4. Bake the cake in the preheated oven for 35 minutes, until the top is golden brown, puffed, and split along the center. A toothpick inserted into the thickest part should come out clean or with a few moist crumbs. If the top browns too quickly, cover loosely with foil for the last 10 minutes.
5. Remove the cake from the oven and let it cool in the pan for 10 minutes. Use the parchment overhang to lift the cake onto a wire rack. Let it cool completely. Meanwhile, whisk together the confectioners' sugar and fresh lemon juice in a small bowl until smooth and pourable. Drizzle the glaze over the cooled cake, letting it run down the sides. Allow the glaze to set for a few minutes before slicing.
