Peanut Butter Cup Brownies {with cocoa powder}

Fudgy Peanut Butter Cup Brownies Recipe - PhotoOne Bowl No Fuss Peanut Butter Cup Brownies for holiday cookie #3.  Cookies and bars fall in the same category for me and we are big chocolate lovers so our list had to include a brownie!

This recipe is adapted from my favorite easy homemade brownie recipe from inspired taste. They are a must make indulgent treat. These brownies are dense, moist, and have the fudgy texture we love. They are super chocolatey (and not too sweet) with the special addition of peanut butter and peanut butter cups.

These Peanut Butter Cup Brownies come together easily with cocoa powder and less than 10 ingredients in one bowl.

To make the brownies all you have to do is melt the butter, whisk in the sugar, then the eggs and vanilla.  Finally fold in the flour, cocoa powder and salt.  Pour the batter into your parchment lined pan.

Finally bake, cool, cut and try and not eat the entire batch 😉.  We made these as part of our 12 days of Christmas cookies, but they are great any time of the year.   They are an especially good use of leftover Halloween candy.
