How to Make Reese's Pieces Bars:

• Begin by preheating your oven to 350°F (175°C). Prepare your 9x9 baking dish by either lining it with parchment paper or greasing it lightly with a thin layer of butter.
• In a mixing bowl, combine the softened butter and both sugars, blending them together until smooth and creamy. (You can achieve this either by hand or by using a hand/stand mixer for added convenience.)
  3/4 cup butter, softened, plus more for greasing, 1/2 cup granulated sugar, 1/2 cup packed light brown sugar
• Add vanilla into the mixture and stir it in thoroughly.
  1 tsp. vanilla extract
• In a large bowl, combine flour, baking powder, baking soda and salt. Gently incorporate the flour mixture with the butter-sugar mixture, making sure the batter is fully combined.
  2 cups all-purpose flour, 2 tsps. baking powder, 1/2 tsp. baking soda, 1/2 tsp. table salt
• Fold in 1/2 cup of the Reese's Pieces and all of the chocolate chips.
  1 cup Reese's Pieces candies, divided, 1/2 cup semi-sweet chocolate chips
• Spread the resulting batter evenly into your 9x9 dish. For a finishing touch, sprinkle the additional Reese's Pieces on top, pressing them in only slightly.
• Slide your baking dish into the preheated oven and bake for approximately 20 minutes. Keep a close eye on it; the bars should be ready when a toothpick inserted into the center comes out with just a few crumbs attached. While the edges may not turn golden, the bottoms should be lightly browned.
• Allow your baked bars to cool. Once they have reached a comfortable temperature, slice them into squares,
