Line an 11x7" brownie pan with parchment paper. Set aside.
Add the cake mix, eggs, butter, and extract to a large mixing bowl. Stir together mixing, just until evenly combined. The batter will be thick.
1 15.25 oz box strawberry cake mix, 2 eggs, 1/3 cup salted butter, 1 tsp strawberry extract
Using a spatula scrape the batter into the prepared pan, and spread it out in an even layer.
Bake the brownies at 350° for 18-22 minutes, or until a toothpick inserted in the center comes out clean.
Remove them from the oven and let them cool completely.
Using the edges of the parchment paper, remove the brownies from the pan and transfer them to a waiting cutting board.
