# What You Need:

→ Dry Ingredients

01 - 2 1/4 cups all-purpose flour
02 - 1 teaspoon baking soda
03 - 1/2 teaspoon salt

→ Wet Ingredients

04 - 3/4 cup unsalted butter, melted and slightly cooled

→ Mix-ins

09 - 1 cup Cadbury mini eggs, chopped

# Directions:

01 - Preheat oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving overhang for easy removal.
02 - In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
03 - In a large mixing bowl, whisk melted butter with brown sugar and granulated sugar until smooth and combined.
04 - Add eggs and vanilla extract to the butter mixture, whisking until fully incorporated.
05 - Gradually fold dry ingredients into wet mixture using a spatula, mixing just until combined. Do not overmix.
06 - Gently fold in chopped Cadbury mini eggs and half of the pastel M&Ms.
07 - Spread dough evenly into prepared pan. Sprinkle remaining M&Ms and additional mini egg pieces over the top for decoration.
08 - Bake for 23-26 minutes, or until edges are golden and center is just set. Do not overbake for soft bars.
09 - Remove from oven and allow to cool completely in the pan before lifting out and cutting into bars.

# Expert Suggestions:

01 -
  • These bars stay impossibly soft and chewy days later, unlike most cookie recipes that harden up.
  • The pastel M&Ms don't melt into the dough—they stay whole and colorful, making every bite feel like a celebration.
  • You can have them cooling on the counter in under an hour, perfect for last-minute holiday gatherings.
02 -
  • The difference between soft and dense bars comes down to that one minute—underbaked is your friend here, so trust the jiggle test more than the timer.
  • Room temperature eggs aren't just a suggestion; cold eggs will seize up when they hit the warm melted butter and your dough will look broken and sad.
  • Not all pastel M&Ms are created equal—some brands melt into the bars while others stay intact, so stick with one brand once you find your favorite.
03 -
  • If you can't find Cadbury mini eggs, any hollow chocolate eggs work, but avoid ones with liquid centers unless you like chocolate surprise puddles in your bars.
  • Toast your flour lightly in a dry skillet for thirty seconds before measuring—it won't change the flavor, but it adds a subtle nuttiness that grounds all the sweetness.
  • Cut the bars while they're still slightly cool to the touch, using a sharp knife dipped in hot water between each cut for clean edges.
