Ingredients

Scale
  • 1/2 cup unsalted butter, melted
  • 1 cup packed brown sugar
  • 1/2 cup granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon pure vanilla extract
  • 1 cup all-purpose flour (can swap with gluten-free flour for GF option)
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon salt
  • 1 cup mini M&Ms (or any mini chocolate candies)
  • 1/4 cup rainbow funfetti sprinkles

Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×9-inch baking pan with butter or line it with parchment paper.
  2. Mix the melted butter with both sugars using a whisk or mixer until smooth and glossy, about 1-2 minutes.
  3. Add eggs one at a time, beating well after each addition, then mix in vanilla extract until fully combined and shiny.
  4. In a separate bowl, whisk together flour, baking powder, and salt to prevent clumps.
  5. Gradually fold the dry ingredients into the wet mixture using a rubber spatula, stopping when just combined to avoid overmixing.
  6. Gently fold in the mini M&Ms and funfetti sprinkles, reserving a few to sprinkle on top.
  7. Spread the batter evenly in the prepared pan, smooth the top, and scatter the reserved M&Ms and sprinkles.
  8. Bake for 22-25 minutes until edges are golden and the center looks set but slightly soft.
  9. Cool completely in the pan on a wire rack before cutting into small bars.

Notes

Do not overmix after adding flour to keep blondies chewy, not cakey. Use room temperature eggs for better emulsification. If edges brown too fast, cover loosely with foil halfway through baking. For dairy-free, use vegan butter and dairy-free mini M&Ms. Bars can be stored at room temperature for 3 days, refrigerated for a week, or frozen.
