Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

  • All-purpose flour

  • Granulated sugar

  • Unsalted butter

  • Eggs

  • Fresh lemon juice

  • Lemon zest

  • Baking powder

  • Salt

  • Powdered sugar (for optional glaze)

  • Milk (for optional glaze)

Directions

  1. I preheat my oven to 350°F (175°C) and line a baking pan with parchment paper.

  2. I cream together the butter and sugar until light and fluffy.

  3. I beat in the eggs one at a time, then stir in the lemon juice and zest.

  4. In another bowl, I whisk together flour, baking powder, and salt, then gradually fold it into the wet mixture.

  5. I spread the batter evenly in the prepared pan and bake for about 20–25 minutes, or until the edges are set and a toothpick inserted comes out clean.

  6. If I want to add glaze, I mix powdered sugar with a little milk and lemon juice, then drizzle it over the cooled bars before cutting.

Servings and timing

This recipe makes about 12 to 16 lemon brownie bars, depending on how I cut them. It usually takes me 10 minutes to prepare the batter and about 25 minutes to bake, with an additional 15 minutes for cooling before slicing.

Variations

I sometimes add white chocolate chips to the batter for a creamy sweetness that complements the lemon flavor. For a slightly different touch, I sprinkle shredded coconut on top before baking. If I want a more intense citrus kick, I use a combination of lemon and lime zest.

storage/reheating

I store the lemon brownie bars in an airtight container at room temperature for up to 3 days. If I want to keep them longer, I refrigerate them for up to a week. They also freeze well for about 2 months. To reheat, I let them come to room temperature or warm them briefly in the microwave. Lemon Brownie Bars Recipe

FAQs

Can I make lemon brownie bars ahead of time?

Yes, I often make them a day in advance, and they taste even better the next day as the lemon flavor deepens.

Can I use bottled lemon juice instead of fresh?

I prefer using fresh lemon juice for the best flavor, but bottled juice works in a pinch if that’s what I have on hand.

How do I know when the bars are done baking?

I look for slightly golden edges and test with a toothpick—if it comes out clean or with a few moist crumbs, the bars are ready.

Can I make these gluten-free?

Yes, I substitute the all-purpose flour with a 1:1 gluten-free baking flour, and the texture stays just as fudgy.

Do I have to use the glaze?

No, I sometimes skip it when I want a lighter treat. The bars are delicious plain, but the glaze adds an extra layer of sweetness and tang.

Conclusion

These lemon brownie bars are one of my favorite desserts when I want something sweet but not too heavy. I love how the tartness of the lemon balances the rich, chewy texture. Whether I serve them at a party, pack them for a picnic, or keep them as a personal treat, they always brighten my day.
