M&M Blondies Recipe



These easy and delicious bars are like a cross between chocolate chip cookies and brownies. You get a bit of the caramel-brown butter flavor that many love about chocolate chip cookies, but with the thick and moist texture of brownies. The peanut M&M's add a colorful touch, but you can also use regular chocolate chips. — Allison Beck

  • 1 package (about 2 ½ cups) light brown sugar
  • 1 stick (½ cup) butter
  • 2 eggs
  • 1 teaspoon vanilla
  • 1 cup flour
  • ½ teaspoon salt
  • 1 ½ cups peanut M&M’s


Preheat the oven to 325 degrees. Grease a 9-by-13-inch baking pan. You can also use a smaller baking pan for thicker blondies, and just bake a bit longer.

Combine the brown sugar and butter in a small saucepan. Heat over medium heat until the butter is melted together and the whole mixture just begins to bubble. Remove and let come to room temperature. This will take about 20 minutes; you can speed it up by putting the pot in the fridge if need be.

When the butter and sugar have cooled, beat in the eggs and vanilla. Add the flour and salt, and then gently stir in the M&M’s. Pour into the prepared pan and bake 25-30 minutes, until the top has gotten slightly puffed and crusty. Cool, and cut into small rectangles.
