Step 1

Start by preheating the oven to 325F then line a 9x5 or an 8x5 loaf pan with parchment paper then set aside.

Step 2

Slightly melt the cookie butter in the microwave or over a double boiler and pour it into the prepared lined loaf pan, place in the freezer and allow to chill fully. This can take 15-30 minutes depending on how hot the cookie butter was.

Step 3

In a large bowl melt the butter and the oil in the microwave or on the stove top in a medium saucepan.

Step 4

If you melted the butter in a saucepan transfer to a large bowl, if not just add in the granulated sugar and the brown sugar to the butter and whisk until the mixture is fully combined.

Step 5

Add in the egg and the vanilla and whisk to combine. Whisk in the flour, cocoa powder, and salt until the flour mixture disappears. Fold in the chocolate chunks.

Step 6

Pour 1/2 of the brownie batter into the prepared baking pan (remove the frozen cookie butter sheet first), spread it evenly then place the frozen cookie butter sheet on there again. Top with the rest of the brownie batter, spread the brownie batter to cover the full loaf pan, and bake in the preheated oven for 28 minutes.

Step 7

You will know your brownies are ready when you insert a toothpick in the center and it comes out with just a few wet crumbs. Let the brownies cool down completely before slicing into them and enjoying!
