Chocolate Peppermint Cookies

Preheat the oven to 350°F (175°C) and line baking sheets with parchment paper.

Cream together the margarine and sugar in a large bowl until light and fluffy, about 3–4 minutes using an electric mixer on medium speed.

Add the peppermint flavoring and egg whites to the margarine mixture, beating on medium speed until well combined.

Whisk together the all-purpose flour, cocoa, baking powder, and salt in a separate bowl.

Fold the dry ingredients into the wet ingredients using a spatula until just combined; do not overmix.

Drop rounded teaspoons of dough onto the prepared baking sheets, spacing them about 2 inches apart.

Bake for 10–12 minutes until the cookies are set and the edges are lightly firm to the touch.

Allow cookies to cool on the baking sheet for 2–3 minutes, then transfer to a wire rack to cool completely.
