Peanut Butter Cookie Pizza is a fun and delicious dessert twist on a classic cookie. It starts with a chewy peanut butter cookie base, is topped with gooey marshmallows, and finished with melty chocolate chips for a crowd-pleasing treat that’s ready in under 20 minutes.
In a large bowl, cream butter, peanut butter, and sugars for 2-3 minutes.
Add the egg and vanilla and beat for another 2-3 minutes. Add the flour and mix just until combined.
Spread the dough onto a greased 12-inch pizza pan. Bake for 12 minutes. Sprinkle with the marshmallows, and then sprinkle chocolate chips on top. Bake for 5-6 more minutes or lightly browned.
