Ingredients

Scale
  • 1 cup unsalted butter, softened (227g)
  • 1 cup packed brown sugar (200g)
  • ½ cup granulated sugar (100g)
  • 2 large eggs, room temperature
  • 1.5 teaspoons pure vanilla extract
  • 1.5 cups all-purpose flour (190g)
  • 1.5 cups old-fashioned rolled oats (135g)
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 cup M&Ms (175g), standard size
  • 1 cup mini pretzels, roughly crushed (60g)

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. Cream together the softened unsalted butter, brown sugar, and granulated sugar using an electric mixer on medium speed for 3-4 minutes until light and fluffy.
  3. Add the eggs one at a time, mixing well after each addition. Then pour in the pure vanilla extract and mix until glossy.
  4. In a separate bowl, whisk together the all-purpose flour, old-fashioned rolled oats, baking soda, and salt.
  5. Slowly add the dry ingredients to the wet mixture, mixing on low speed until just combined. Avoid overmixing.
  6. Fold in the M&Ms and roughly crushed mini pretzels gently with a spatula, keeping the candy shells intact.
  7. Spread the batter evenly in the prepared pan and smooth the top with a spatula.
  8. Bake for 22-25 minutes or until edges are golden brown and a toothpick inserted near the center comes out with a few moist crumbs.
  9. Remove from oven and let cool completely in the pan on a wire rack. Use the parchment overhang to lift the bars out, then cut into squares or rectangles.

Notes

Do not overmix the batter to keep bars tender. Fold in M&Ms and pretzels gently to avoid breaking candy shells. Bars firm up as they cool, so slight wobble in the center when done is normal. Use parchment paper for easy removal. For gluten-free, substitute flour and oats accordingly. For dairy-free or vegan, use plant-based butter, egg replacers, and dairy-free candy.
