Instructions

  1. Step 1: Preheat oven to 350°F. In a medium bowl, whisk together 2 cups gluten-free rolled oats, 1 cup gluten-free all-purpose flour, and 1/2 tsp baking soda.
  2. Step 2: In a large bowl, cream 1/2 cup softened unsalted butter with 1 cup brown sugar and 1/2 cup granulated sugar until light and fluffy, about 3 minutes using a hand mixer.
  3. Step 3: Beat in 2 large eggs one at a time, then add 1 tsp vanilla extract and mix until combined.
  4. Step 4: Gradually add the dry oat and flour mixture to the wet ingredients, stirring until just incorporated.
  5. Step 5: Fold in 3/4 cup mini chocolate chips and 3/4 cup mini rainbow candy-coated chocolates evenly.
  6. Step 6: Press the dough evenly into a greased 9x9 inch baking pan and bake for 25-28 minutes until golden brown on top and a toothpick inserted comes out clean.
  7. Step 7: Cool completely in the pan before cutting into bars.
