Ingredients Overview

This dessert keeps things clean and uncomplicated, but each ingredient plays a key role in achieving the perfect texture and bold lemon flavor.

Key Ingredients

• All-purpose flour: Provides structure while keeping the crumb soft. Make sure to spoon and level your flour to avoid a dense texture.

• Granulated sugar: Sweetens the dessert and helps create a slightly crisp top while balancing the tartness of the lemon.

• Lemons (zest and juice): Fresh is best! Lemon zest brings intense citrus oils and aroma, while juice adds the bright, tangy flavor.

• Eggs: Add richness and bind everything together. They also contribute to the dessert’s tender, cake-like texture.

• Butter (melted): Adds a rich, buttery flavor and keeps the crumb moist without creaming.

• Baking powder: Gives lift and lightness.

• Salt: Just a pinch enhances all the other flavors.

• Vanilla extract: Rounds out the lemon flavor with a subtle warmth.

Optional Add-In: A splash of milk or sour cream can be added for an even softer crumb, especially if you like a moister lemon bar or cake texture.

Dairy-Free Option: Substitute melted coconut oil or plant-based butter for the melted butter.

Step-by-Step Instructions

This one-bowl recipe makes baking feel effortless. You don’t need a stand mixer — just a whisk, a spoon, and a little love.

1. Preheat and Prep

Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch square pan (or similar size) with parchment paper, leaving an overhang for easy removal.

2. Mix Wet Ingredients

In a large mixing bowl, whisk together:

• 2 large eggs

• ¾ cup granulated sugar

• 1 tablespoon lemon zest

• ¼ cup fresh lemon juice

• ½ cup melted butter

• 1 teaspoon vanilla extract

Whisk until fully combined — the mixture should be smooth, bright, and slightly glossy.

3. Add Dry Ingredients

To the same bowl, sift or gently stir in:

• 1 cup all-purpose flour

• 1 teaspoon baking powder

• ¼ teaspoon salt

Use a spatula or wooden spoon to mix until just combined. Do not overmix — it’s okay if a few small lumps remain.

Optional: Fold in 1–2 tablespoons of sour cream or milk for a softer, more tender crumb.

4. Bake

Pour the batter into the prepared pan and smooth the top with a spatula.

Bake for 22–26 minutes, or until the edges are lightly golden and a toothpick inserted in the center comes out clean. Don’t overbake — you want the interior to remain soft and just barely set.

5. Cool and Finish

Let the dessert cool in the pan for 10–15 minutes, then use the parchment to lift it out and transfer to a wire rack.

Once fully cooled, dust with powdered sugar or drizzle with a simple lemon glaze (powdered sugar + lemon juice) for extra citrus flavor and shine.

Slice into squares or bars and serve.

FAQs

Q1: Can I double the recipe for a larger pan?

A1: Yes — this recipe doubles beautifully. Use a 9×13-inch pan and increase the baking time to 28–32 minutes. Keep an eye on the edges for golden color.

Q2: Can I use bottled lemon juice?

A2: While you can, it’s not recommended. Fresh lemon juice and zest provide brightness and natural flavor that bottled versions just can’t match.

Q3: How do I store leftovers?

A3: Store cooled slices in an airtight container at room temperature for up to 2 days or refrigerate for up to 4. They also freeze well — just wrap tightly and thaw before serving.

Q4: Can I make this gluten-free?

A4: Yes, just use a 1:1 gluten-free flour blend that includes xanthan gum. The texture remains soft and slightly chewy.

Q5: Is this more like a cake or a bar?

A5: It’s a hybrid — softer than a lemon bar, but denser and more moist than a sponge cake. Think of it as a lemon snack cake with a brownie-like format.

Q6: Can I add a glaze or frosting?

A6: Definitely. A quick lemon glaze (powdered sugar + lemon juice) adds a glossy, tangy topping. For more indulgence, try cream cheese frosting.

Q7: How can I make it more tart?

A7: Increase the lemon zest to 2 tablespoons and add a few drops of lemon extract for extra pucker. You can also reduce the sugar slightly if you prefer sharper citrus notes.
