Calling all peanut butter lovers, this cookie cake is for you! As well as for anyone looking for a fast, easy, no mixer dessert that’s a guaranteed hit. It’s basically a giant cookie, minus the hassle of rolling and chilling the dough. Peanut butter is incorporated three ways — in the dough, with Reese’s Pieces, and with peanut butter cups. And if that wasn’t enough, I broke out some fun chocolate and orange sprinkles because sprinkles make everything better. If you don’t impulse buy and hoard seasonal sprinkles at Target like I do, use regular chocolate jimmies. The PB cookie cake is slightly crisp around the edges and buttery soft and chewy in the center. There’s lots of texture from the sprinkles, the crunchy Reese’s Pieces shells, and it’s exploding with big time peanut butter flavor. It’s just irresistible.

Recipe Ingredients 

I know this homemade cookie ‘cake’ is made in a pie plate, but it required a deeper baking dish since it’s so fully loaded. Whatever you want to call this giant peanut butter cookie masterpiece, here’s what you’ll need to make it: 

Unsalted butter Egg Light brown sugar Vanilla extract Creamy peanut butter All-purpose flour Salt Sprinkles  Reese’s Pieces  Mini peanut butter cups

Storage Instructions

At room temp: Let the peanut butter cookie cake pie cool completely, then wrap tightly with foil. Leftovers will last up to 5 days. In the freezer: Cut the cake into slices and then seal in a freezer bag for up to 3 months. If your freezer often leaves baked goods with freezer burn, you might want to wrap each individual slice with plastic wrap and then seal in a freezer bag.
