A chewy peanut butter cookie studded with plenty of peanut butter M&M’s and baked in a skillet. This peanut butter M&M skillet cookie is just waiting for you to take a slice!

Chewy peanut butter M&M cookies are always a welcome treat at our house. Baking them into a big skillet cookie makes the process even easier and gives you lots of the best chewy center parts. It is peanut butter and chocolate cookie goodness at its finest!
This post was originally from 2015. I thought it was high time to make this bad boy again.
When I pulled up the post, the pictures of Little Dude melted my heart. He was always been such a helper.
I couldn’t bare to take those pictures out. He is just too dang sweet. But I did update the pictures of the cookie itself.

I will let you read the original post and see the fun pictures of little dude from when he was an itty bitty sous chef.
I don’t know if you guys know this or not, but I have a sweet tooth. I thought I might go ahead and fess up to it!

Peanut Butter M&M Skillet Cookie
Ingredients
- 1/2 cup butter
- 1/2 cup peanut butter
- 3/4 cup packed brown sugar
- 1/2 cup granulated sugar
- 1 large egg
- 2 tsp vanilla
- 1 tsp salt
- 3 T milk powder
- 1/2 tsp baking powder
- 1/4 tsp baking soda
- 1 cup all-purpose flour
- 3/4 cup whole wheat flour (you can use all all-purpose)
- 1 bag peanut butter M&M’s
Instructions
- Preheat oven to 350 F
- Melt butter in mixing bowl, then stir in peanut butter.
- Mix in brown sugar and sugar and stir well.
- Add in egg and vanilla and stir until completely uniform.
- Stir in the salt, milk powder, baking powder and baking soda until really well mixed.
- Stir in flours until just combined. Fold in most of the M&M’s, reserving some to place on top.
- Press into a 9″ skillet or cake pan. Arrange remaining candies on the top of the cookie.
- Bake for 30-35 minutes.
- (This is the hardest part!) Wait for at least 45 minutes before cutting and serving. If you jump the gun, it will still taste great but will not hold its shape.
