How to Make It
Get ready to bake some delicious cookies!
1. Combine
In the bowl of a stand mixer, combine melted butter, brown sugar, granulated sugar, and vanilla. Mix on low until combined. While mixing, add the eggs one at a time.
2. Mix
Add the dry ingredients: all-purpose flour, baking soda, corn starch, and kosher salt. Mix until just combined.
3. Fold
Use a rubber spatula to fold in the M&Ms, chocolate chips, ruffle chips, and sprinkles evenly throughout the dough.
4. Chill
Line a cookie sheet with parchment paper and scoop 24 even dough balls. Cover with clear wrap and chill in the refrigerator for 30 minutes. If the dough is too soft, refrigerate for an additional 30 minutes after scooping.
5. Preheat
Preheat the oven to 350°F (175°C). Space 4 cookie dough balls about 2 inches apart on the baking sheet and bake for 12 minutes or until the edges are set.
6. Shape
As soon as the cookies come out of the oven, use a round cookie cutter or glass to reshape the cookies into circles. Optionally, gently press in a few additional chocolate chips, M&Ms, chips, and sprinkles into the tops.
7. Cool
Let the cookies cool for 5 minutes on the baking sheet before transferring them to a cooling rack to cool completely.
How to Store It
Fridge: Store cookies in an airtight container for up to 5 days.
Freezer: Yes, they freeze well for up to 3 months.
Reheat: Microwave on low for 10-15 seconds to warm.
Tips for Best Results
