I made these cookies a couple of weeks ago... the recipe is a conglomeration of 5-6 different "monster" cookies I found online. We really enjoyed these cookies - even took some to the neighbors... they're still talking to us, so the cookies must have been good to them, too!
2 sticks (1/2 lb.) unsalted butter, softened
1/2 c. white sugar
1.5 c. brown sugar
1 Tbsp. vanilla
1.5 c. flour
1 tsp. baking powder
1/2 tsp. baking soda
1 tsp. salt
1.5 c. oats
3/4 c. M&Ms
1 c. chocolate chips (I mixed milk & semi-sweet)
1/2 c. peanut butter chips
2.5 c. Rice Krispies
Preheat oven to 375F.
Cream butter and sugars until fluffy. Add eggs one at a time, beating well. Add vanilla and beat.
Combine flour, baking powder, baking soda, and salt. Add to butter mixture and mix until combined.
Add in remaining ingredients - oats, M&Ms, chocolate and peanut butter chips.
Add Rice Krispies last, and mix only until just combined. Be careful to not overmix.
Use a cookie scoop to create balls of dough for the cookie sheet. Bake about 10 minutes, until golden brown, and then cool them on a rack.
Makes ~5 dozen.
