Preheat the oven to 350. Grease a 9x13 inch pan and line with parchment paper. Mix the brownie crust ingredients together medium bowl, then pour into the bottom of the pan. Use a spoon to smooth to all the edges.
In a stand mixer, cream the butter and sugar until fluffy. Add the oil, eggs, and vanilla, and mix until combined. Add the peanut butter and mix fully.
