These brownie cookies are rich, fudgy, and full of chocolate flavor with a crinkle top. Made in one bowl and ready in just 20 minutes for an easy brownie meets cookie treat!
Preheat oven to 350°F. Line a baking sheet with a silicone mat or parchment paper and set aside. Melt butter and set aside to cool for a few minuts.
In a large bowl stir together 1 cup butter, 2 cups sugar and 1/4 cup oil. Add the 1 cup cocoa powder and 1 Tablespoon vanilla and mix together. Then add in 2 eggs and stir until combined.
Next add 2 1/2 cups flour and 1 teaspoon baking powder and mix with a spoon until smooth. Fold in 1/2 cup chocolate chips (save a few to add on top).
Using a large cookie scoop, scoop out the dough and place onto the baking pan. Bake for 10-12 minutes, or until the edges are lightly crisp and the middles are still soft. Sprinkle flake sea salt on top while the chocolate is still hot.
Allow cookies to cool on the pan for a few minutes and then transfer to a cooling rack.
