These Cadbury Egg Cookie Bars are soft, chewy, and loaded with crunchy chocolatey bites—perfect for Easter or any spring celebration. They come together quickly with simple ingredients and are always a crowd favorite!
Preheat the oven to 350°F (175°C). Line an 8x8 baking pan with parchment paper to easily lift bars out and avoid sticking.
In a large bowl, whisk together the melted butter and brown sugar until fully combined and slightly glossy.
Mix in egg, egg yolk, and vanilla extract until smooth.
Stir in baking powder, salt, and flour until just combined. Avoid overmixing for soft, chewy bars.
Gently fold in the chopped mini Cadbury eggs.
Spread the batter evenly into the prepared pan and smooth the top with a spatula. If you’d like, sprinkle a few extra chopped Cadbury eggs over the top.
Bake for 20-25 minutes until the top turns a golden color and a toothpick inserted in the center comes out clean. Avoid overbaking to maintain chewiness.
Let the bars cool completely in the pan before slicing and serving.
