These are the cookies to bake when you aren't sure what you're craving. They're packed with M&Ms, oats, butterscotch chips, pecans, and crispy rice cereal.
Preheat oven to 375°F. Line a sheet pan with parchment paper or a silicone baking mat.
In the bowl of a stand mixer fitted with a paddle attachment, beat together the butter and sugars until light and creamy, about 1-2 minutes. Add the eggs one at a time, followed by the vanilla and mix until combined.
Add the flour, salt, baking powder, and baking soda and mix on low until just combined. Add the oats, chips, and nuts, M&Ms, and crispy rice cereal and mix until just combined.
Drop large rounds (I use a #20 - 3 tablespoon cookie scoop) onto the prepared sheet pan, 6-8 per pan. Bake until edges are golden brown and centers are just barely set, about 12 minutes.
Let cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely. Store in an airtight container for several days.
