Lemon Pound Cake Bars

If you’re craving a bright, citrusy dessert that’s simple to make and easy to serve, these lemon pound cake bars check all the boxes. They have the rich, buttery flavor of a classic lemon pound cake, but they’re baked in a 9×13 pan and cut into squares for a more casual, shareable treat.

Think of these as lemon cake bars — soft and tender with plenty of fresh lemon flavor from both zest and juice. A simple glaze on top adds just the right amount of sweetness and makes them feel a little extra special without adding any fuss.

They’re just as welcome at a spring brunch as they are for an everyday dessert, and they’re a great option when you want something that feels homemade and a little nostalgic without a lot of extra work.

Are These Lemon Bars or Lemon Cake?

These are much closer to a lemon cake than traditional lemon bars.

Classic lemon bars usually have a shortbread crust and a soft, custard-like lemon filling. These lemon pound cake bars skip the crust and custard entirely in favor of a soft, buttery cake with bright lemon flavor throughout.

If you’ve ever wished lemon bars were a little more cake-like, this recipe is exactly that. You get the fresh, zesty flavor of lemon in a texture that’s tender, sliceable, and easy to share — more like a lemon cake, just baked in bar form.

Why You’ll Love These Lemon Pound Cake Bars

• Bright, fresh lemon flavor. Lemon zest and juice work together to give these bars a bold citrus flavor without being overly tart.
• Soft, buttery texture. Like a classic pound cake, but a little lighter and more tender thanks to the bar format.
• Simple, no-fuss mixing. No creaming required — just melt, mix, and bake.
• Easy to slice and share. Baked in a 9×13 pan, these lemon cake bars are perfect for gatherings, brunches, or anytime you need a crowd-friendly dessert.
• Flexible glaze options. Keep it simple with a classic glaze, or swap in lemon juice for an extra pop of citrus.

Key Ingredients and Why They Matter

• Lemons (zest + juice) – The zest is where most of the lemon flavor comes from, giving these bars their bold citrusy taste. The juice adds brightness and helps balance the sweetness.
• Butter – Melted butter keeps the mixing simple and gives these bars their rich, buttery flavor without needing a creaming step.
• Granulated sugar – Sweetens the bars and helps create that soft, tender crumb you expect from a pound cake-style dessert.
• Eggs – Provide structure and richness, helping the bars hold together while still staying soft.
• All-purpose flour – Gives the bars their structure while keeping the texture tender rather than dense.
• Baking powder – This is what makes these a bit lighter than a traditional pound cake, giving them a softer, more cake-like texture that works perfectly for bars.

How to Make Lemon Pound Cake Bars

Prep the pan and oven.
Heat the oven to 375°F and grease a 9×13-inch baking pan so the bars release easily after baking.

Whisk the dry ingredients.
Combine the flour, baking powder, and salt. This helps distribute everything evenly so the bars bake up with a consistent texture.

Melt the butter and mix the batter.
Melt the butter in a large saucepan, then remove it from the heat. Stir in the sugar, followed by the eggs, mixing well after each addition. Add the dry ingredients, then the lemon zest and juice, mixing just until combined.

Spread and bake.
Transfer the batter to the prepared pan and spread it evenly. Bake for 25–35 minutes, or until the top is lightly golden and the center is set.

Cool before glazing.
Let the bars cool completely in the pan before adding the glaze so it sets nicely on top.

Make the glaze and finish.
Stir together the confectioners’ sugar and milk (or lemon juice) until smooth, then drizzle over the cooled bars before slicing.

How to Store

Room temperature: Store the bars in an airtight container at room temperature for up to 2–3 days. If your kitchen is warm, you may prefer to refrigerate them to keep the glaze set.

Refrigerator: Stored in the refrigerator, they’ll keep for up to 5 days. Let them come to room temperature before serving for the best texture.

Freezer: These bars freeze well. Wrap them tightly (individually or in layers with parchment between them) and store in an airtight container for up to 2 months. For best results, freeze without the glaze. Thaw at room temperature before serving.
