Ingredients

• 2 and 3/4 cups all-purpose flour, measure by spooning into the cup and leveling, this gives structure without being too dense.
• 1 and 1/2 teaspoons cornstarch, helps create a tender, soft crumb.
• 1 teaspoon baking soda, provides lift and a light texture.
• 1/2 teaspoon salt, balances sweetness and enhances flavor.
• 1 cup unsalted butter, melted and cooled, gives rich flavor and a soft, chewy bar when cooled.
• 1 cup packed light or dark brown sugar, adds moisture and a subtle caramel note.
• 1/2 cup granulated sugar, helps with browning and a slight crisp top.
• 2 large eggs, at room temperature, bind the ingredients and add richness.
• 2 teaspoons pure vanilla extract, adds warm aromatic flavor.
• 1 and 1/4 cups mini or regular-size M&Ms, for color, crunch, and candy-coated chocolate bursts.
• 3/4 cup semi-sweet chocolate chips, for melty chocolate pockets throughout the bars.

Step-by-step Instructions

1. Preheat and prepare. Preheat the oven to 350°F (177°C) and position the oven rack in the center of the oven for even baking.
2. Line the pan. Line a 9×13-inch baking pan with parchment paper, leaving some overhang to lift the bars out easily after cooling.
3. Mix the dry ingredients. In a medium bowl, whisk together the flour, cornstarch, baking soda, and salt until evenly combined.
4. Combine the sugars and butter. In a large bowl, stir together the melted, cooled butter, the packed brown sugar, and the granulated sugar until smooth and glossy.
5. Add eggs and vanilla. Beat the eggs into the butter and sugar mixture, then stir in the vanilla extract until well incorporated.
6. Bring wet and dry together. Stir the wet mixture into the dry ingredients until just combined. Do not overmix to keep the bars tender.
7. Fold in mix-ins and transfer. Fold in the M&Ms and semi-sweet chocolate chips so they are distributed evenly, then transfer the dough into the prepared pan and spread it into an even layer.
8. Bake until set. Bake for 26 to 30 minutes, until the edges are lightly browned and a toothpick inserted in the center comes out with a few moist crumbs attached. Baking times vary with ovens, so start checking at 26 minutes.
9. Cool before slicing. Let the bars cool in the pan for at least 1 hour so they set fully, then use the parchment overhang to lift them out and cut into squares. For cleaner slices, chill briefly before cutting.

Tips, Storage & Variations

• Tips
  • Use room temperature eggs so they combine easily with the melted butter without re-solidifying it.
  • Spread the dough evenly and tap the pan lightly on the counter to remove air pockets for a uniform bake.
  • If the edges brown too quickly in your oven, tent the pan loosely with foil for the last few minutes.
• Storage
  • Store bars in an airtight container at room temperature for up to 3 days.
  • For longer storage, refrigerate for up to 1 week, bringing to room temperature before serving for softer texture.
• Freezing
  • Freeze uncut bars wrapped tightly in plastic wrap and then foil for up to 3 months. Thaw overnight in the refrigerator and bring to room temperature before cutting.
• Flavor variations using existing ingredients only
  • Use mini M&Ms for more even candy distribution and slightly softer bites.
  • Increase the semi-sweet chocolate chips to 1 cup for extra melty chocolate pockets.
  • Swap light brown sugar for dark brown sugar for a deeper molasses note.

FAQ
Q: Can I use salted butter instead of unsalted?
A: Yes, but reduce added salt or omit it to avoid an overly salty result.

A: You can, but using both balances chewiness and browning. Using only brown will make bars moister and richer.

Q: Can I press extra M&Ms on top before baking?
A: Yes, pressing a few extra on top after spreading the dough creates a prettier finished look.

Q: How do I know when the bars are done?
A: The edges should be lightly browned and a toothpick in the center should come out with a few moist crumbs.

Q: Can I halve the recipe?
A: Yes, you can halve ingredients and bake in a smaller pan, but baking time will change. Monitor closely.

Q: Are mini M&Ms better than regular for these bars?
A: Mini M&Ms distribute more evenly and create a smoother texture, but regular M&Ms work fine if you prefer larger candy pockets.

Q: Can I use different candy instead of M&Ms?
