Why You’ll Love These Lemon Brownies

These are perfectly soft, melt-in-your-mouth lemon brownies made easily with powdered lemonade mix. This is a variation of lemon bars that you never knew you needed! Here’s why:

  • Brownies with a twist. Lemon brownies put a bright and tart, citrusy twist on your classic fudgy brownies. They fall somewhere between a blondie and a lemon square, and we are 100% here for it.
  • Soft brownie texture. These lemon brownies are moist, cakey brownies with a soft, tender crumb bursting with lemonade flavor. The secret to all that flavor is powdered lemonade mix! 
  • Lemon glaze. Glaze these fluffy lemon brownies with a delectable icing packed with even more lemon flavor. Seriously delish.

Ingredients You’ll Need

Here are some helpful ingredient notes before we dive into this easy brownie recipe. Don’t forget to scroll to the recipe card below the post for a printable list of ingredients.

  • Butter – Brought to room temperature.
  • Lemonade Powder – I use Country Time powdered lemonade mix. Feel free to use any brand of mix that you’d like.
  • Sugar – You can make this recipe with granulated sugar or light brown sugar.
  • Eggs – One whole egg, plus 2 yolks. The extra yolk adds richness.
  • Vanilla – Use real vanilla extract and not imitation vanilla.
  • Dry Ingredients – All-purpose flour and baking powder (not baking soda, don’t mix them up!).
  • Glaze – Made from powdered sugar combined with lemonade (or lemon juice) and lemon zest.

How to Make the Best Lemon Brownies With Glaze

These are the easy steps to perfect lemon brownies topped with creamy lemonade glaze. Scroll down to the recipe card for printable recipe directions.

  • Combine the wet ingredients. Start by creaming together butter and sugar with lemonade powder. Then, beat in your egg and both yolks, along with the vanilla.
  • Add the dry ingredients. Slowly mix in the flour and baking powder until the ingredients are just combined, being careful to not overmix.
  • Bake. Spread the brownie batter into a greased 8×8-inch baking dish. Pop the brownies into the oven to bake at 350ºF for 15-20 minutes. They should be just set in the center. Don’t overbake them!
  • Cool and glaze. Allow the brownies to cool completely. Afterward, sift powdered into a bowl and add lemonade or lemon juice, plus lemon zest. Whisk the glaze together and then pour it over the cooled brownies. Let the glaze set (about 1 hour), then slice and serve!

Tips for Success

These are my top tips for perfect lemon brownies:

  • Don’t overbake. These lemon brownies continue to set up in the pan while they cool, so be sure to take them out of the oven when they’re just set. Overbaking will lead to dry, crumbly brownies.
  • Avoid over-mixing. Over-mixing brownie batter leads to dense, tough brownies. Stir the dry and wet ingredients together until they’re just combined.
  • Add-ins. Stir white chocolate chips, shredded coconut, or chopped nuts (like walnuts or pecans) into the batter for a little extra somethin’ somethin’.
  • Serve. Serve these brownies topped with a scoop of vanilla ice cream, homemade lemon curd, and whipped cream for a citrusy spin on a brownie sundae! Add a drizzle of strawberry syrup to take things over the top.

How to Store

  • To Store. Store your lemon brownies at room temperature in an airtight container. They’ll stay fresh for up to 3-4 days. 
  • Freeze. These brownies are the perfect candidates for freezing! You can freeze them before or after adding the glaze. Wrap the cooled brownies airtight in a double layer of plastic wrap and freeze them for up to 2-3 months. Defrost them at room temperature before serving.

    These are delicious. I was wondering if I were to quadruple this recipe would you think I still need to use all those egg yolks(8)? Your opinion would be appreciated. I love your recipes!

      1. MichaelleTrottier

        Yes two 9×13 glass pans. I already made a double batch in my 9 x 13 and they worked perfect. It just seems like sooo many eggs to do the two pans, but hey it’s a heck of a lot of butter too and I’m not worried about that! I was wanting to make them for church pot-luck dinner. They are devine! Thank you so much! Did you create this recipe? I haven’t found one of your recipes yet that wasn’t a hit!

    I want to quadruple this recipe for an event, do you think I seriously need to use that many egg yolks extra (8)? Just asking for your advice.
