Grab a glass of milk and enjoy a slice of this perfect Giant M&M Cookie! As well, you may hear this referred to as a Pizookie, which is a combination of the words ‘pizza’ and ‘cookie’.

I made this Giant M&M Cookie for Lincoln’s birthday. It’s what he requested instead of a cake. It turned out beautiful and delicious! It rivals the best store-bought skillet cookie.

Another birthday favorite is Chocolate Marshmallow Fudge.

There are really no special ingredients in this large cookie. In fact, you can make individual cookies with the dough if you choose. However, one large cookie is quicker to make instead of scooping out individual cookies. Not to mention baking the in 3 or 4 different batches.

  • 1 cup butter

  • 1 large egg
  • 1 and1/2 teaspoon vanilla extract

  • 1 teaspoon salt
  • 1 and 3/4 cups M&M’s Milk Chocolate Candies

After mixing the dough, you press it into a greased cookie sheet. It needs to be flat or even slightly lower in the middle. You can also bake in a large skillet. I used a 12-inch pizza pan. If your pan is smaller it’ll need to cook longer so watch it closely.

Furthermore, don’t press your cookie dough closer than 1-inch to the edge of the pan. It will expand and cookie over causing a mess in your oven. (I know from personal experience.)

As well, you can use any candy you want. Try M&Ms, chocolate chips, nuts, or chopped candy bars.

Once baked, you can decorate the large cookie any way you want. I enjoy it warm with vanilla ice cream, but kids tend to dig into a large wedge plain and straight from the pan.


If you have leftovers you can store them in an airtight container on the counter.

    Love this recipe. It takes away the effort of having to scoop our individual cookie sized dough on a cookie sheet.
