Prep Time15 minutes
Cook Time25 minutes
Total Time40 minutes
Servings: 24 bars

Ingredients

  • 1/2 cup unsalted butter 113 g, softened
  • 1 1/4 cups packed brown sugar 250 g
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon salt
  • 1/2 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1 cup all-purpose flour 124 g
  • 1 1/2 cups quick cooking oats
  • 2 cups mix-ins see notes for suggestions

Instructions

  • Preheat the oven to 350°F (175°C). Line a 9x13-inch pan with foil and spray with cooking spray, or grease the pan directly.
  • In the bowl of an electric mixer fitted with the paddle attachment, cream together the softened butter and packed brown sugar until light and combined.
  • Add the egg and vanilla and beat until incorporated.
  • Add the salt, baking soda, and cinnamon and mix briefly to combine.
  • Add the flour and mix until just combined, then stir in the quick cooking oats with a spatula until evenly distributed.
  • Fold in the 2 cups of mix-ins until evenly combined.
  • Press the sticky dough evenly into the prepared pan, spraying your hands with cooking spray if needed. Optionally sprinkle a few extra mix-ins on top.
  • Bake for about 25 minutes; the center may still be slightly jiggly. Do not overbake.
  • Cool completely in the pan before lifting out the foil (if used) and slicing into 24 bars.

Equipment

  • 9x13 inch Baking Pan
  • Mixing Bowl
  • electric mixer with paddle attachment
  • Spatula
  • Measuring cups and spoons
  • Aluminum foil (optional)

Notes

  • Use any combination of chips, candies, nuts, or toffee as mix-ins.
  • Mini candies make the bars more visually appealing on top.
  • Foil makes it easier to remove the bars from the pan.
  • Do not overbake; bars firm up as they cool.
  • Quick oats give a softer texture than old-fashioned oats.
