Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.

In a large bowl, cream the butter, granulated sugar, and brown sugar until smooth.

Add the egg and vanilla extract, mixing until well combined.

Gradually add the dry ingredients to the wet mixture, mixing gently until a dough forms.

Scoop about 2–3 tablespoons of dough and roll into balls, placing them 2–3 inches apart on the baking sheet.

Bake for 10–12 minutes until the edges are lightly golden and centers are soft.

Press nine pastel M&Ms into each cookie while warm to create bunny faces.

Allow to cool for about 5 minutes before transferring to a wire rack.
