Christmas M&M Cookie Bars
⭐ Ingredients
- ½ cup (113g) unsalted butter, melted
- ¾ cup brown sugar
- ¼ cup white sugar
- 1 large egg
- 2 tsp vanilla extract
- 1 ½ cups all-purpose flour
- ½ tsp baking soda
- ½ tsp salt
- 1 cup Christmas M&Ms (red + green minis or regular)
- ¾ cup chocolate chunks or chocolate chips
🥣 Instructions
1. Prep
- Preheat oven to 350°F (175°C).
- Line a baking pan (9×13 or 9×9 for thicker bars) with foil or parchment and spray lightly.
2. Make the Dough
- Mix melted butter + brown sugar + white sugar until smooth.
- Add egg + vanilla and combine.
- In another bowl, whisk flour + baking soda + salt.
- Add dry ingredients to wet mixture and mix until a soft dough forms.
- Fold in half of the M&Ms and half of the chocolate chunks.
3. Spread in Pan
- Press cookie dough evenly into the baking pan.
- Sprinkle the remaining M&Ms and chocolate chunks on top (this gives the look in the photo).
4. Bake
- Bake 20–25 minutes, depending on your pan size.
- Edges should be golden but the center slightly soft — it will set as it cools.
5. Cool & Slice
- Let cool fully for clean cuts.
- Slice into squares or bars.
