Preheat your oven to 350 degrees and prepare a baking sheet with a silicone mat or non-stick spray and set aside.

Cream butter and both sugars in the bowl of a stand mixer with a paddle attachment.

Add egg and vanilla and mix.

Add dry ingredients into a medium bowl and give a quick whisk and add to wet ingredinets.

Mix on low until there are no dry spots remaining and the dough comes together.

Fold in the Cadbury mini eggs and mini chocolate chips.

Scoop out about 2 1/2-3 Tablespoon balls of dough and place them 2 inches apart on a baking sheet. Bake for 10-13 minutes or until the edges are golden brown.

Remove from the oven and allow to cool 5-10 minutes on the baking sheet then transfer to a wire rack to cool completely.
