Heat your oven to 350°F and line a baking sheet with parchment paper.
In a large mixing bowl, beat the butter, white sugar, and brown sugar together for 1-2 minutes until light and fluffy.
Add the vanilla extract and egg, and mix until smooth and well combined.
In a separate bowl, whisk together the flour, baking soda, and salt. Gradually mix the dry ingredients into the wet ingredients until a soft dough forms.
Gently fold in the chocolate chips and Easter M&Ms until evenly distributed.
Use a cookie scoop to drop dough balls onto the prepared baking sheet. Bake for 9-10 minutes, or until the edges are set but the centers are still soft.
As soon as you take the cookies out of the oven, press extra M&Ms on top to form bunny faces! For ears, carefully cut M&Ms in half and press them into the warm cookies.
Let the cookies cool for a few minutes before transferring them to a wire rack.
