Lemon Brownies

Mostly sweet but a little tart, these Lemon Brownies are bursting with real lemon flavor! They're certainly different from traditional brownies that you might be used to, but they're every bit as chewy, rich, and moist as the classic chocolate version!Be sure to check out the how-to VIDEO just below the recipe!

Steps

Preheat oven to 350F (175C) and grease and flour a 9x9 baking pan or line with parchment paper. Set aside.
In a large bowl, combine melted butter, sugar, and lemon zest. Stir well.
Add egg and egg yolk, lemon juice, lemon extract, and vanilla extract. Stir again until well-combined.
In a separate, medium-sized bowl, whisk together flour, cornstarch, baking soda, and salt.
Stir dry ingredients into wet until completely combined. Pour into prepared 9x9 pan and transfer to 350F (175C) oven. Bake 30 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Allow to cool completely before covering with glaze.
LEMON GLAZE
- Once lemon brownies have cooled, prepare glaze by whisking together powdered sugar, 1 tablespoon lemon juice, and lemon zest until well-combined. If mixture is too stiff, add remaining lemon juice, 1 teaspoon at a time, until desired consistency is reached (when you lift a spoon or whisk out of the mixture, the glaze that drizzles off the spoon and falls back into the bowl should hold its ribbon shape for a few seconds before fading back into the rest of the glaze).
- Pour glaze over lemon brownies, use a spatula to smooth evenly over the surface.
- Allow glaze to harden (about 15-30 minutes) before slicing and serving lemon brownies.

I've made these multiple times and they've always been great. Recently took them to a party where they were devoured (even without the glaze). Thanks for writing such genius recipes Sam!

Tried this recipe and my mix was really thick at the end but pretty sure it was thicker than it was supposed to. I couldn’t really finish mixing it well with my whisk. So I’m thinking either my eggs where not big enough or I put too much flour but I followed the recipe.. also my Baking mold was 8x8 so I cooked it longer but my top was getting really brown and it looked fine but ended up not being cooked enough. It still taste Amazing and I’m gonna eat them anyway but would love a few tips. Thank you

Good lord! These are insanely good. I have been on a lemon kick for a few years now and I have never tasted anything so balanced and perfect in terms of sweet and sour. Lemon brownies! Delicious!

I made these (finally). The batter is very heavy which concerned me. Trust the recipe. You will really enjoy these. They are so bright with lemon flavor!! Definitely a five star!
