Cadbury Egg Cookie Bars (Print Version)

Chewy bars rich with Cadbury mini eggs and pastel M&Ms for a colorful treat.

# Ingredient List:

→ 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
05 - 1 cup light brown sugar, packed
06 - 1/2 cup granulated sugar
07 - 2 large eggs, at room temperature
08 - 2 teaspoons pure vanilla extract

→ Mix-ins

09 - 1 cup Cadbury mini eggs, chopped
10 - 1 cup pastel M&Ms

# Steps:

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 extra mini egg pieces over the top for decoration.
08 - Bake for 23 to 26 minutes, or until edges are golden and center is just set. Do not overbake to maintain soft texture.
09 - Remove from oven and allow to cool completely in pan before lifting out and cutting into bars.

# Helpful Hints:

01 -
  • They bake in under 30 minutes, which means you can go from craving to eating dessert faster than you'd think possible.
  • The combination of chewy cookie base with the slight crunch of candy shells hitting your teeth is honestly addictive.
  • One batch yields enough to share, freeze, or eat secretly over three days without anyone knowing.
02 -
  • Underbaking these bars by 1 to 2 minutes is actually the move—they firm up as they cool, and pulling them at the right moment (edges set, center slightly jiggly) gives you that perfect chewy texture that makes people ask for seconds.
  • Not all Cadbury mini eggs are created equal; the ones sold around Easter have a thinner shell and better chocolate-to-candy ratio than the year-round versions, so timing your shopping matters.
03 -
  • Brown your butter by melting it and letting it sit for a few minutes before using—this deepens the flavor without changing the recipe structure, and the bars become noticeably more complex.
  • Save some M&Ms and mini eggs to press into the top during the last 2 minutes of baking; they'll stick and look intentional rather than randomly scattered.
