1-Step 1: Mix the dry ingredientsWhisk together 1 1/2 cups all-purpose flour, 3/4 cup cocoa powder, 1 teaspoon baking powder, and 1/8 teaspoon salt in a medium bowl. This quick step helps spread the leavening and cocoa evenly through the dough. If you want a stronger chocolate aroma, use Dutch-process cocoa for a smoother, darker flavor.

2-Step 2: Cream the butter and sugarIn a separate bowl, beat 3/4 cup softened unsalted butter and 1 cup granulated sugar until smooth and creamy. This usually takes a few minutes with a hand mixer or stand mixer. The mixture should look light and fluffy, which helps create a soft bite once the cookies bake.

3-Step 3: Add the egg and vanillaBeat in 1 large room-temperature egg and 1 teaspoon pure vanilla extract until fully combined. Room-temperature ingredients blend better and help the dough come together without overmixing. At this stage, the dough should look silky and well mixed.

4-Step 4: Combine the doughGradually add the dry ingredients into the wet mixture. Mix just until the dough forms and no dry streaks remain. If the dough feels sticky, add a little more cocoa powder for rolling, but avoid adding too much flour or the cookies may taste dry.

5-Step 5: Roll out the doughDivide the dough in half for easier handling. Roll each portion out on parchment paper or a silicone mat lightly dusted with cocoa powder or flour. I like cocoa powder here because it adds a little extra chocolate flavor and keeps the dough looking dark and rich. Roll to an even thickness so the cookies bake evenly.

6-Step 6: Chill the rolled doughChill the rolled dough for at least 1 to 2 hours. This step is important because it helps the cookies keep their shape and prevents spreading. If you are short on time, place the sheets of dough flat in the coldest part of the fridge so they firm up faster.

7-Step 7: Cut the cookiesPreheat your oven to 350°F, which is 175°C, and line baking sheets with parchment paper. Use cookie cutters to cut out shapes, then re-roll the scraps as needed. Work quickly so the dough stays cold. If the dough softens, return it to the fridge for a few minutes before cutting again.

8-Step 8: Bake the cookiesPlace the shapes on the prepared baking sheets and bake for 11 to 12 minutes. The cookies should look set around the edges but still soft in the center. Since these are chocolate cookies, it can be a little hard to judge color, so watch the texture instead of waiting for browning.

9-Step 9: Cool before decoratingLet the cookies cool on the baking sheet for 5 minutes before moving them to a wire rack. This short rest helps them firm up so they do not break. Once fully cooled, decorate with royal icing or easy glaze icing and finish with assorted sprinkles.

10-Step 10: Serve and enjoyThese cookies are ready for parties, lunchbox treats, or a simple dessert at home. The full recipe makes about 24 cookies, sized 3 to 4 inches each, and the total time is about 3 hours 30 minutes including chilling and icing set time. It is a great baking project for home cooks, students, busy parents, and anyone who loves a pretty cookie tray.
