How to Make M&M’s Valentine’s Day Cookie Bars
Step 1: Preheat the Oven
Preheat your oven to 350 degrees Fahrenheit. This ensures your cookie bars bake evenly.
Step 2: Prepare Your Baking Pan
Line a 9×13 aluminum cake pan with foil. Leave some overhang on the sides to help remove the bars after baking. Generously spray the foil with nonstick cooking spray.
Step 3: Mix Wet Ingredients
In the bowl of a stand mixer, beat together butter, granulated sugar, and brown sugar. Mix until fluffy. Then add in eggs and vanilla extract, continuing to beat until well combined.
Step 4: Combine Dry Ingredients
Lower the speed of your mixer. Gradually add in flour, baking soda, and salt. Mix until just combined; do not overmix.
Step 5: Add Mix-Ins
Gently fold in M&M’s and mini chocolate chips. Reserve some M&M’s and mini chocolate chips for topping later.
Step 6: Transfer Dough to Pan
Transfer your cookie dough into the prepared baking dish. Spread it evenly across the pan using a rubber spatula.
Step 7: Add Toppings
Press additional M&M’s and mini chocolate chips into the top of the cookie dough for extra flair before baking.
Step 8: Bake Your Cookie Bars
Place your filled baking dish on the middle rack of your preheated oven. Bake for 35 to 40 minutes or until they turn golden brown around the edges.
Step 9: Cool & Cut
Once baked, let your cookie bars cool completely in the pan before lifting them out using the foil overhang. Cut into squares and enjoy!
