Instructions
Preheat the oven to 350 degrees F. Line cookie sheets with parchment paper or nonstick baking mats.
In a very large mixing bowl, combine the sugars, peanut butter, and butter. Mix well. Add the eggs one at a time and beat well between additions. Add vanilla. Mix well.
Combine oats, flour, baking soda, salt, and baking powder in a medium bowl and whisk well. Add to wet ingredients and mix until combined. Fold in the Reese’s Pieces, mini cups, and chocolate chips.
Cover and allow batter to rest for 45-60 minutes at room temperature.
Measure out ¼ cup-sized portions and place them on the prepared cookie sheets, no more than 4 to a sheet. Flatten the cookies with your palm a bit, and press additional candies and sprinkles into cookies, if desired.
Bake for 15-18 minutes, until the edges are lightly golden brown. Do not overbake. Remove from oven and allow to cool 5 minutes before transferring to wire racks. When cool, store in large resealable plastic bags.
