Loaded Peanut Butter Cookie Cake — Peanut butter is used 3 WAYS: In the dough, with peanut butter cups, and Reese’s Pieces!! EASY, no mixer, super soft center with chewy edges, and tastes AMAZING!!
Table of Contents
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

How to Make a Peanut Butter Cookie Cake
If you know how to make regular cookies, then you can definitely handle this cookie cake made with peanut butter. I actually think it’s easier than making regular PB cookies since there’s no need to roll the dough into balls!
Here’s how the peanut butter cookie cake is made:
- Mix together the cookie dough as you usually would, gently stirring in the sprinkles and Reese’s Pieces last.
- Turn the dough into a 9-inch pie plate and top with peanut butter cups.
- Bake the cookie cake in a pre-heated oven until the center is set and a toothpick inserted into the center comes out clean or with a few moist crumbs, but no batter.
Serve this cookie cake at your next special celebration or birthday party!
Recipe FAQs
No, I recommend using a ‘traditional’ peanut butter brand like Jif or Skippy. Natural and homemade peanut butters are oiler and tend to separate in baked goods.
Sure thing! I loaded this PB cookie cake with peanut butter cups and Reese’s Pieces, but you may use butterscotch chips, chocolate chips, peanut butter chips, chopped nuts, chopped candy bars — whatever you want to stuff inside the peanut butter cookie dough!
Nope! If you don’t have a 9-inch pie plate on hand, you can use an 8×8-inch square baking dish instead. Just make sure that whatever baking dish you use instead of the pie plate is deep enough since this cookie cake is fully loaded!
Yes, just make sure to slightly underbake the cookie cake so it stays soft, chewy, and moist for a few days if you know you’ll be serving it at a later date.
If you’re craving a classic chocolate chip cookie cake, make this chocolate chip cookie pie instead. It’s SO good and there’s no nut butter of any kind in the recipe.
Use any color sprinkles you’d like in this recipe. I used brown and orange fall-themed sprinkles to match the Reese’s Pieces, but any color will work.
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.

Loaded Peanut Butter Cookie Cake
Ingredients
- ½ cup unsalted butter, 1 stick, melted
- 1 large egg
- 1 cup light brown sugar, packed
- 1 tablespoon vanilla extract
- heaping 1/3 cup creamy peanut butter
- 1 cup all-purpose flour
- ½ teaspoon salt, or to taste
- ½ cup brown and orange fall-themed sprinkles, substitute with chocolate jimmies
- ½ cup Reese’s Pieces, plus more for sprinkling
- about 10 to 12 miniature peanut butter cups, unwrapped
Instructions
- Preheat oven to 350F, spray a 9-inch glass pie plate with cooking spray; set aside.
- To a large, microwave-safe bowl add the butter and heat on high power to melt, about 1 minute.
- Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
- Add the peanut butter and stir to combine.
- Add the flour, salt, and stir until just combined, don’t overmix.
- Add the sprinkles and stir to combine.
- Add the Reese’s Pieces and stir to combine.
- Turn batter out into prepared pan, smooth the top lightly with a spatula, and add the peanut butter cups, evenly spaced over the surface. Push them down so that they’re flush with the dough.
- Evenly sprinkle 1 to 2 tablespoons of extra Reese’s Pieces over the surface for visual appeal, lightly tapping them down.
- Bake for about 26 to 29 minutes, or until center is set and a toothpick inserted in the center comes out clean or with a few moist crumbs, but no batter.
- Allow pie to cool on a wire rack for at least 30 minutes before slicing and serving.

Thanks for the five star review and I’m glad you loved it!
I saw this pin and thought it would be a fun family reunion activity for my youngster prebreakfast camp to make together for a hiking treat later that day. I want to use to pizza pans and triple the recipie so there will be more room for ten pair of little hands to pat it out and decorate. (five each pan) Then it could be cut up in reasonable squares later for dispersal. How thick does the batter need to be in the pan to avoid burning or crumbly cookies? It looks so good.
If you triple the recipe, the thickness of the batter won’t change; you’ll just have a lot more of it to be divided among more pans. I have only made the recipe as written so can’t make suggestions beyond that.
We make cookie pie for my kids every year on their birthday. My daughter requested peanutbutter this year, this recipe fits that order perfectly. She loved it!
Thanks for trying the recipe and I’m glad it came out great for you!

This is my kind of pie, easy and packed full of peanut butter! :)
Guilty of being a holiday sprinkle impulse buyer, and yet I always think I need more! :) This is the ultimate peanut butter cookie pie – so much deliciousness in one place! I have your Peanut Butter Comfort cookbook and have enjoyed many of the recipes. This is another peanut butter recipe to add to the arsenal!
hey girl this looks so good!
I’d love a slice of this pie right now! Also, you make the prettiest cookie pies ever! Pinned!
You had me at peanut butter and cookie – but peanut butter cookie pie is absolutely fabulous and I LOVE how much PB and chocolate is in this one :) looks so good!!
Halloween is right around the corner and this would be the perfect party pie! Our street has an annual garage party and while this has given me an idea on what to take, I haven’t thought much about what I’m going to be.
I love that you’re actually getting dressed up! And yes this is perfect for a garage party!
Joan Jett and Rex Kwon Do took this incredible PB cookie pie to the garage party. It did disappear (which is always a good sign because there was probably enough food for the entire subdivision)! Axl Rose and Slash from across the street definitely took us all in the costume department.
Love the comment and that you were Joan Jett! Sounds like the costumes were excellent and anytime a dessert can disappear amidst all that other food it’s a success!
