In the mixing bowl, cream together butter and sugars for 3 minutes. Add eggs one at a time, followed by peanut butter and vanilla extract.

Scrape down the sides of the bowl with a spatula.

Add oats, salt, and baking soda. Mix until well combined.

Using a spatula, fold in chocolate chips, peanut butter chips, M&Ms, and sprinkles.
