Directions

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

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

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

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.
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.
