Ingredients

Chocolate Chip Cookie Bar Base

¾ cup unsalted butter melted and slightly cooled
¾ cup light brown sugar packed
¼ cup granulated sugar
1 large egg room temperature
1 teaspoon vanilla extract
1 ¾ cups all-purpose flour
½ teaspoon baking soda
½ teaspoon salt
¾ cup semi-sweet chocolate chips
¾ cup chopped Cadbury Mini Eggs

Buttercream Frosting

½ cup unsalted butter softened
2 cups powdered sugar
1 teaspoon vanilla extract
Blue gel food coloring

Topping

½ cup Cadbury Mini Eggs whole and chopped
Speckling Mixture
1 teaspoon cocoa powder
1 teaspoon vanilla extract
1-2 teaspoons water

Instructions

For the cookie bar base

Preheat the oven to 350°F (180°C). Line an 8x8-inch baking pan with parchment paper, leaving overhang for easy removal.
In a large mixing bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add the egg and vanilla extract and mix until fully combined.
Stir in the flour, baking soda, and salt just until a soft dough forms. Fold in the chocolate chips and chopped Cadbury Mini Eggs.
Press the dough evenly into the prepared pan. Bake for 22–26 minutes, until the edges are lightly golden and the center is set but still soft.
Let the cookie base cool completely before frosting.

For the buttercream

In a medium mixing bowl with a hand mixer, beat the softened butter and vanilla extract until smooth and creamy. Gradually add the powdered sugar until completely combined. Add a small amount of blue gel food coloring at a time, and mix until you reach your desired pastel shade. Beat until light and fluffy.
Spread the buttercream evenly over the cooled cookie bars using an offset spatula.

Decorate

Press whole and chopped Cadbury Mini Eggs gently into the frosting.
In a small bowl, whisk together cocoa powder, vanilla extract, and water until combined. Dip a clean pastry brush or paintbrush into the mixture and flick lightly over the bars to create a speckled effect.
Allow the frosting to set slightly in the refrigerator before slicing.

Notes

The center of the cookie will be soft, and the edges will be set and start to brown when it’s ready to come out of the oven. The middle will continue to set as it cools.
Allow the Cadbury egg cookie bars to cool completely before adding frosting to keep it from melting.
Overbaked cookie bars will be very dry and crumbly. The center doesn’t need to be fully set or firm, so keep an eye on them as they bake!
