Lemon Brownies

Recipe adapted from Alyssa Rivers, The Recipe Critic.

This recipe I have made so many times I have lost count! It is a perfect quick recipe to make for your family and friends.

There are two tips that make this recipe work:

  • Use room temperature butter. You can’t use cold butter or almost room temperature butter for this recipe. If you do, the batter will be lumpy. If your butter isn’t room temperature, when its baking, bubbles will form then eventually will burst. The brownie will come out with an uneven top layer. When you put the glaze on top, it will look lumpy and rough.
  • One large lemon works much better than one small lemon. If small lemons are the only option, I would use two small lemons. Lemon zest is an important part in this recipe, and you need as much as you can.

The hardest part about this recipe is letting it cool after it is baked. It must be completely cooled before the glazed is put on top. If not, the glaze will just run off the brownie. To speed up the cooling process you can put the brownie in the fridge or freezer.

When the brownie is completely cooled, you can put the glaze on top.

I have also done this recipe with limes and oranges in place of the juice and zest. It’s a great take on a Spring dessert!
