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.

  1. Okay so first I am 12 and probably not the best source of information on this recipe, but in my opinion, this is almost better than normal chocolatey brownies. I made this recipe and I thought the batter was a little thick so I put it in the oven for 10 minutes after that I put it in the oven for 5 more minutes setting the time cooking at 15 minutes ( which is how long the brownies are spoused to be cooked for ). Since I did not have any powdered sugar and I really wanted to make the brownies I resolved that problem by instead of using a glaze I made a lemon simple syrup. Anyways 100/10 definitely recommend. Hope this helps.

  2. This gets better (in theory?) add small blips of preserves. Strawberry or raspberry (your on your own with the seed problem ?) pink lady brownies! Blackberry or blueberry dream fairy brownies. Y’all now know what kinda books I grew up reading…lol. on a different note can something be done about all the adds and the media bar? It’s very distracting and sweets need my full focus. ?

  3. Here in Brazil there’s lemonade sweet juice powder. That’s the same that you use in your recipe? Thanks
