This Pizookie is the ultimate treat—warm, gooey cookie dough packed with Reese’s, chocolate chips, and M&M’s, all baked in a deep-dish skillet for a delicious dessert!
Preheat oven to 350°F. Lightly grease or spray a 9-inch cast-iron skillet or 9-inch cake pan. Set aside.
In a medium bowl, cream room-temperature butter (see note 1), granulated sugar, and brown sugar for about 2–3 minutes. Add in egg and vanilla. Mix until combined.
In a separate bowl, stir together flour (see note 2), baking soda, baking powder, and salt. Add dry ingredients to the wet and mix until a dough forms. Do not overmix.
Divide the dough in half. Press one half into the bottom of the skillet or cake pan and layer halved Reese’s cups on top.
To the remaining cookie dough, add the milk chocolate chips and peanut butter M&M’s. Stir to combine, then press that remaining cookie dough on top of the Reese's cups and smooth the dough into 1 even layer. The Reese’s cups should be covered with dough.
Bake for 20–25 minutes until the edges are light golden brown, keeping the center slightly soft for a perfect Pizookie.
Serve immediately with ice cream and hot fudge if desired.
Notes
Note 1: Use room-temperature butter. If it’s too soft or melted, the edges may burn before the center bakes properly.Note 2: When measuring flour for this recipe, spoon flour into the measuring cup and level it off with a table knife. Pressing the measuring cup into the flour container can lead to using too much.Storage: This Pizookie is best fresh, warm, and gooey. For leftovers, cool completely, cover tightly, and store at room temperature for up to 2 days. Reheat for a just-baked feel!
