Easy Cookie Cake Recipe

Calling all peanut butter lovers, this pie is for you. As well as for anyone looking for a fast, easy, no mixer dessert that’s a guaranteed hit. 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 pie is a spinoff on one I made a few years back that’s been a reader favorite over the years. It uses my go-to blondie recipe that’s so easy.

The cookie cake / pie 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 bigtime peanut butter flavor. It’s just irresistible.

What’s in Peanut Butter Cookie Cake? 

I know this ‘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 cookie masterpiece, here’s what you’ll need to make it: 

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

How to Make Peanut Butter Cookie Cake 

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 homemade cookie cake until the center is set and a toothpick inserted into the center comes out clean or with a few moist crumbs, but no batter.

Can I Use Natural Peanut Butter?

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.

Tips for Making a Homemade Cookie Cake 

After melting the butter, wait a minute or two before adding in the raw egg. You don’t want to scramble it! 

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. 

Because this peanut butter cookie cake is baked in a pie plate, there’s no need to chill the dough first. Win!

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!!

Ingredients

  • 1/2 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
  • 1/2 teaspoon salt, or to taste
  • 1/2 cup brown and orange fall-themed sprinkles (substitute with chocolate jimmies)
  • 1/2 cup Reese’s Pieces, plus more for sprinkling
  • about 10 to 12 miniature peanut butter cups, unwrapped

Instructions

  1. Preheat oven to 350F, spray a 9-inch glass pie plate with cooking spray; set aside.
  2. To a large, microwave-safe bowl add the butter and heat on high power to melt, about 1 minute.
  3. Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
  4. Add the peanut butter and stir to combine.
  5. Add the flour, salt, and stir until just combined, don’t overmix.
  6. Add the sprinkles and stir to combine.
  7. Add the Reese’s Pieces and stir to combine.
  8. 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.
  9. Evenly sprinkle 1 to 2 tablespoons of extra Reese’s Pieces over the surface for visual appeal, lightly tapping them down.
  10. 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.
  11. Allow pie to cool on a wire rack for at least 30 minutes before slicing and serving.

Notes

Storage: Pie will keep airtight at room temp for up to 1 week.
