There's a recipe from Kraft for Peanut Butter Oatmeal Chocolate Chunk Cookies. They remind me a lot of Monster Cookies. But I just don't want such a big cookie. So I tweaked this one a bit and used mini-M&M's and you get the big taste of Monster Cookies in a reasonably sized cookie.
1 cup (2 sticks) butter, softened
1 cup peanut butter (creamy or crunchy)
1 cup sugar
1 cup brown sugar
1 tbsp. vanilla
1 cup flour
1 cup rolled oats (quick or old-fashioned)
1 tsp. baking powder
1 tsp. baking soda
1/2 tsp. salt
1 cup mini-M&Ms
1 cup chocolate chips (mini or standard)
Cream sugars, butter, and brown sugar. In another bowl mix flour, oats, baking powder, soda, and salt. Add eggs to butter and sugar mixture one at a time. Gradually add dry ingredients. Mix in M&Ms and chocolate chips. Drop by teaspoons onto cookie sheet. Bake at 375 for 8-10 minutes, until just starting to brown around the edges. Cool on the cookie sheet for 2 minutes before removing to a cooling rack.
