  2. Preheat the oven to 350°F (175°C).
  3. Combine the wet ingredients: In a bowl, whisk together melted butter and peanut butter. Add sugars and whisk until glossy. Add eggs and vanilla, whisking until smooth.
  4. Mix the dry ingredients: In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
  5. Combine the mixtures: Add dry ingredients to wet mixture and gently fold until just combined.
  6. Fold in chocolate chips.
  7. Press the dough into the prepared pan, smoothing the top.
  8. Add M&M’s and sprinkles on top.
  9. Bake for 18 to 24 minutes until edges are golden and center is barely set.
  10. Add remaining M&M’s on top as soon as removed from the oven.
  11. Cool completely in the pan, about 1 to 1.5 hours.
  12. Optional drizzle: Melt white chocolate chips and oil in the microwave and drizzle over the cooled bars.
  13. Slice and serve warm or at room temperature.
