Make the Dough
In a bowl, whisk together flour, baking powder, salt, and cocoa powder.
In a separate bowl, cream butter and sugar until light and fluffy.
Add egg, vanilla, and milk; mix until combined.
Add red food coloring until a deep red color forms.
Gradually mix in dry ingredients until a soft dough forms.
Chill the Dough
Divide dough into two discs.
Wrap tightly and refrigerate for 30–45 minutes.
Chilling helps the cookies hold their heart shape during baking.
Roll & Cut
Preheat oven to 350°F (175°C).
Roll dough on a lightly floured surface to about ¼-inch thickness.
Cut with heart-shaped cookie cutters.
Place cookies on a parchment-lined baking sheet.
Bake
Bake for 8–10 minutes, until edges are set but centers remain soft.
Let cookies cool on the baking sheet for 5 minutes before transferring.
Decorate (Optional)
Dust with powdered sugar, drizzle with white chocolate, or add a light cream cheese glaze for classic red velvet flavor.
