As a former pastry chef, lemon bars were always a customer favorite, but I always thought they would be even better with the fudgy texture of a classic brownie…which is where this recipe comes in!
Made in one bowl with white chocolate, fresh lemon juice, and plenty of lemon zest, they have a slightly dense, fudgy texture and are topped with a sweet, not too runny lemon glaze. You don’t even need a mixer to make them!!
These are fudgy, not cakey, so if that’s what you’re craving, my soft and fluffy lemon loaf cake is your girl instead!
How to Make Them
1
Make the brown butter. This is an extra step, but it’s so worth it! The butter’s nuttiness brings richness to the brownies, balancing the brightness of the lemon.
2
Mix in the white chocolate.
3
Whisk the wet ingredients for about 1 minute before adding the butter/white chocolate mixture. This is key to achieving crinkle tops!
4
Fold in the dry ingredients. Don’t overmix, or the brownies will be more tough and dense.
While I love a dense and fudgy treat, I also love a light and fluffy one too, which is where my moist lemon cake with raspberry filling comes in…it’s the perfect lemon dessert!
5
Spread the brownie batter into an 8×8 baking pan. Then bake the brownies until the top is lightly golden brown!
6
Cover with lemon icing. Let the icing set before cutting. For clean slices, wipe it clean between cuts!
By the way, if you have extra lemons lying around, freeze the zest and juice, and then use them whenever you want to bake up my lemon poppy seed cake with cream cheese frosting or cinnamon roll-inspired lemon sweet rolls!
