Equipment

Ingredients

  • 16.5 oz sugar cookie dough package
  • 1 stick unsalted butter softened
  • ⅔ cup granulated sugar
  • ¼ teaspoon salt
  • ¾ cup all-purpose flour
  • 2 large eggs room temp
  • 1 teaspoon pure vanilla extract
  • 2 tablespoons fresh lemon juice
  • 2 tablespoons lemon zest
  • Powdered Sugar for garnish, optional
US Customary - Metric

Instructions

  • Preheat oven to 350 degrees.
  • Spray an 8X8 inch baking dish with cooking spray.
  • Add a little flour to your fingers to break apart cookie dough. Evenly press sugar cookie dough into the bottom of the baking pan.
  • Bake for 12 minutes. Remove pan from oven and cool for 10 minutes.
  • While the cookie crust cools, add butter, sugar, salt and flour to bowl of a mixer and beat until combined.
  • In a separate bowl, whisk together the eggs, vanilla extract, lemon juice, and lemon zest until combined.
  • Pour into the flour mixture and mix at medium speed until smooth and creamy, about 2 minutes.
  • Carefully spread lemon brownie batter evenly over cooled cookie dough (dough will still be warm and may move around just a bit.)
  • Bake for 20-25 minutes, or until they turn golden on the edges and a toothpick inserted in the center comes out clean. Cool and serve. I like to sprinkle a bit of powdered sugar on top. It's delish!

How to Store 

Allow them to cool completely after baking. Then, store in an airtight container and keep them at room temperature. If you prefer to keep them refrigerated, they tend to firm up a bit and are best enjoyed after sitting at room temperature for a bit.
How long will lemon brownies?
When stored at room temperature, they will keep them soft for up to 5 days.
Can I freeze lemon brownie bars?
Yep! Cool them completely and then store them in an airtight container either in a single layer or with a piece of parchment in between the layers. Store in the freezer for up to three months. Thaw them out in the fridge overnight or on the counter for an hour or two.
