Melt the Butter: Melt 1/2 cup of butter in a saucepan over medium-low heat. Cool for 5-8 minutes.

Mix Wet Ingredients: In a bowl, whisk melted butter, 1/2 cup granulated sugar, and 1/4 cup brown sugar until smooth. Add 1 egg and 1 tsp vanilla, mix until glossy.

Add Color: Stir in 1 tablespoon of red gel food coloring until evenly mixed.

Combine Dry Ingredients: In another bowl, whisk 1 1/2 cups flour, 2 tbsp cocoa powder, 1 tsp baking powder, 1/2 tsp baking soda, and a pinch of salt.

Combine Wet and Dry Mixtures: Fold the dry ingredients into the wet until just combined. Dough will be soft and slightly sticky.

Prepare for Baking: Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.

Scoop and Roll Dough: Use a cookie scoop to portion the dough and roll in red sanding sugar. Place on baking sheets.

Bake the Cookies: Bake for 9-10 minutes until slightly puffy. They should remain soft in the center.

Cool the Cookies: Let cookies cool on the baking sheets for 5-10 minutes before transferring to a wire rack.
