These mixed berry cookie bars are so easy to make and so, so good! I was inspired by this Strawberry Blondies recipe. When I had some mixed berries on hand I decided to try making something similar with berries. It took a couple tries to get them right, but are the perfect mix of a dense cookie like texture with bright fruit flavor. Plus, the prep time is so quick you can easily whip up a batch for your next party!
How to Make Mixed Berry Cookie Bars
Cream together the butter and sugar (1) until it is light and fluffy. Then, you'll mix in the egg and vanilla (2) until it's combined. It will start to look curdled (3) but if you keep mixing it will come together and look a bit like frosting (4). Then, you'll add the flour, salt, baking powder mixture (5) and mix until it forms a dough (6).
At this point, you gently fold in your fruit and then add the mixed berry batter to a parchment lined baking pan and bake. That is it! I topped my baked cookie bars with powdered sugar but that it totally optional.
