Cadbury Mini Egg Cookie Bar Recipe — Crowd‑Pleasing Dessert

Easter Mini Egg Cookie Bars are soft, chewy, and studded with colorful Cadbury Mini Eggs. This simple dessert comes together in under an hour and makes a festive, crowd-pleasing treat for holiday meals, potlucks, or family gatherings.

The base has a buttery, chewy cookie texture that pairs perfectly with the crunchy, pastel-coated mini eggs on top. This recipe is easy to adapt with different candies and sprinkles so you can make it for other holidays year-round.

Every spring I stock up on Cadbury Mini Eggs to use in seasonal treats. I love adding them to easy tray bakes because they add color and crunch without extra work. These cookie bars have the flavor and chew of classic chocolate chip cookies but are faster and simpler to prepare.

Mini Egg Cookie Bars Ingredients

• All-purpose flour – this recipe is written for standard all-purpose flour; a gluten-free all-purpose blend may work as a substitute if needed.
• Baking powder and baking soda – check freshness; they help the dough rise and stay tender.
• Unsalted butter – softened to room temperature for easy mixing.
• Granulated sugar and light brown sugar – the mix of sugars creates a chewy, tender texture.
• Large eggs – use at room temperature for best results.
• Vanilla extract and salt – enhance the flavor of the dough.
• Cadbury Mini Eggs – chopped and divided between the dough and the topping.

How to Make Cadbury Mini Egg Cookie Bars

Preheat the oven to 350°F. Lightly grease a 9×13-inch baking dish and line it with parchment paper, leaving some overhang for easy removal.

Whisk together the flour, baking powder, and baking soda in a medium bowl and set aside.

In a large bowl, cream the softened butter with the granulated and brown sugars until light and fluffy using a stand mixer or electric hand mixer. Beat in the eggs, vanilla, and salt until just combined.

Add the dry ingredients gradually, mixing until a thick cookie dough forms. Fold in 1 1/2 cups of chopped Cadbury Mini Eggs, reserving the remainder for the top.

Press the dough into the prepared pan in an even layer, then sprinkle the reserved chopped mini eggs over the top and press them gently into the dough.

Bake for 25–30 minutes, or until a toothpick in the center comes out clean or with just a few moist crumbs. Avoid overbaking to keep the bars soft and chewy.

Remove from the oven and transfer the pan to a wire rack to cool. Once cooled to room temperature, lift the bars from the pan using the parchment overhang and slice into squares with a sharp knife.

Baking Tips

• Bring butter and eggs to room temperature for a smoother, more even dough.
• Check the bars at 20 minutes to avoid overbaking; they should be golden at the edges but still soft in the center.
• Cool completely before slicing for the cleanest cuts.

How to Measure Flour Correctly

Lightly spoon flour into the measuring cup and level it off with the flat side of a knife. Packing flour into the cup can add too much and make baked goods dry.

Substitutions and Variations

Swap Cadbury Mini Eggs for M&Ms, chopped Rolos, mini peanut butter cups, or chocolate chips. Use seasonal candies or colored M&Ms to customize the bars for different holidays. Be aware that different candies may change the bake time or texture slightly.

Make-Ahead and Storage

You can prepare the dough and refrigerate it, covered, for 2–3 days before baking. After baking, store cooled bars in an airtight container at room temperature for up to 3 days—adding a slice of bread to the container helps keep them soft. Reheat briefly in the microwave for a warm treat, or serve with vanilla ice cream.

To freeze, cut the bars into squares, separate layers with parchment paper, and place them in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before serving.
