Ingredients

Scale
  • 1 cup (2 sticks, 227 g) unsalted butter, browned
  • 1 cup (200 g) packed brown sugar
  • 1/2 cup (100 g) granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 2 1/4 cups (280 g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 1/2 cups (about 270 g) M&M’s (plain or peanut)

Instructions

  1. Brown the butter: In a medium saucepan over medium heat, melt 1 cup (227 g) of unsalted butter. Stir frequently as it foams and then begins to brown — you’ll see tiny brown flecks and smell a toasty, nutty aroma. This should take about 5-7 minutes. Be careful not to burn it; once browned, immediately remove from heat and let it cool for 5 minutes.
  2. Mix sugars and butter: In a large bowl, combine the browned butter with 1 cup (200 g) packed brown sugar and 1/2 cup (100 g) granulated sugar. Use a rubber spatula or mixer to mix until smooth and well combined, about 2 minutes.
  3. Add eggs and vanilla: Crack in 2 large eggs (room temp) one at a time, mixing well after each addition. Stir in 2 teaspoons vanilla extract. The batter will be glossy and thick.
  4. Combine dry ingredients: In a separate bowl, whisk together 2 1/4 cups (280 g) all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon salt.
  5. Incorporate dry into wet: Gradually add the dry ingredients to the wet mixture, folding gently to combine. Don’t overmix — stop when you no longer see dry streaks. The dough will be slightly thick and sticky.
  6. Fold in M&M’s: Add 1 1/2 cups (270 g) M&M’s, stirring gently to distribute evenly without crushing the candies.
  7. Prepare the baking pan: Line a 9×13-inch (23×33 cm) pan with parchment paper, letting some hang over the edges for easy removal, or grease the pan lightly.
  8. Spread the batter: Transfer the dough to the pan and spread evenly with a spatula or your hands (lightly greased), smoothing the top.
  9. Bake: Bake at 350°F (175°C) for 20-25 minutes. Start checking at 20 minutes — the edges should be golden and the center just set but still soft. A toothpick inserted should come out with moist crumbs, not wet batter.
  10. Cool and slice: Let the bars cool completely in the pan on a wire rack, about 30 minutes. Use the parchment edges to lift out the whole slab, then slice into bars.

Notes

Use a light-colored pan to brown butter to avoid burning. Cool butter before mixing to prevent cooking eggs. Fold M&M’s gently to avoid color bleeding. Check bars early as ovens vary; bars firm up as they cool. For chewier bars, bake slightly less. Can prepare dough ahead and bake fresh later.
