Ingredients
Method
Preparation
- Cream the butter and sugars until fluffy and pale.
- Beat in the egg and vanilla, scraping the bowl to combine.
- Whisk the dry ingredients (flour, baking soda, cornstarch, salt) in a separate bowl and mix into the wet ingredients on low speed until just combined.
- Fold in most of the M&Ms and any mini chocolate chips, reserving a handful of M&Ms for topping.
Baking
- Chill the dough for 30 minutes for thicker cookies, or bake immediately.
- Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
- Scoop 1.5 tablespoon balls spacing them a couple of inches apart on the baking sheet.
- Bake for 9 to 11 minutes, until edges are set and centers are still touch soft.
- Press reserved M&Ms on top immediately after baking.
- Cool on the sheet for 5 minutes before transferring to a wire rack.
Notes
Store cookies in an airtight container for 3 to 4 days. For longer storage, freeze baked cookies for up to 2 months or freeze dough balls first before baking.
