These Christmas cookie bars are going to be hit this season! Think blondie meets the chocolate chip cookie with a whole lot of holiday cheer that's ready in 30 minutes!
additional Christmas sprinkles for sprinkling over the baked cookie barsif desired
Instructions
Preheat oven to 350°F. Brush an 8×8-inch square baking pan with a bit of the melted butter and line the pan with parchment paper, leaving a 2-inch overhang on two sides.
In a large bowl, whisk remaining butter and sugars until smooth. Whisk in egg and vanilla until fully incorporated.
Add flour and salt and mix just until moistened (do not over mix). Fold in ½ cup chocolate chips, ⅓ cup of the M&Ms, and jimmies.
Transfer batter to prepared pan and smooth top with a rubber spatula. Sprinkle the top with the remaining M&Ms.
Bake for 20 minutes or until the top is golden brown and a toothpick inserted into the center comes out clean.
Set the pan on a wire rack and sprinkle with additional sprinkles, as desired. Cool completely. Using the parchment overhang, lift the blondies from the pan and transfer them to a cutting board. Cut into squares.
Notes
Store in an airtight container for up to 5 days.You can adjust the chocolate chips, M&Ms, and sprinkles amounts however you’d like. The amounts given here produce a chewy blondie with lots of chocolate and sprinkle flavor. Jimmies are the best choice for adding into the batter as the dye will not bleed. Other sprinkles should be added to the top only of the cookies; if stirred in, they will turn the batter a greenish-brown color.Stir the batter together gently to keep the cookies soft and chewy; Overmixing can cause the brownies to be crumbly and tough.
