To make these monster cookies, I started by dumping some peanut butter, softened butter, eggs, sugar, brown sugar and vanilla into a large mixing bowl.

I used an electric mixer to cream the ingredients together until smooth.

Then I added some quick oats, baking powder and salt to the bowl.

I continued mixing with the electric mixer until all of the ingredients were fully combined.

Then I added some red and green M&Ms to the bowl.

I stirred the M&Ms into the cookie dough.

Then I scooped approximately one inch balls of cookie dough onto a nonstick cookie sheet, making sure to leave at least an inch between the balls.

I baked the cookies until they were just starting to brown around the edges.

Then I removed the cookies from the oven and used a spatula to transfer them from the hot pan to some parchment paper on the counter to cool off.

These chewy oatmeal peanut butter cookies are the perfect Christmas cookie for peanut butter lovers.

Add these Christmas Monster Cookies to your Christmas baking list this holiday season!
