1-Gather and Prepare Ingredients: First, gather ingredients and preheat your oven to 350°F (175°C). Measure 2 and 1/4 cups all-purpose flour, 1/2 teaspoon baking powder, 1/4 teaspoon salt, 3/4 cup softened unsalted butter, 3/4 cup granulated sugar, 1 large egg at room temperature, 2 teaspoons pure vanilla extract, and 15 to 20 unwrapped hard candies. Line baking sheets with parchment paper for easy cleanup.

2-Mix the Dough: In a bowl, whisk the flour, baking powder, and salt together. In another bowl, cream the butter and sugar until light and fluffy, about 2 3 minutes. Beat in the egg and vanilla until fully combined, then gradually mix in the dry ingredients to form a soft dough.

3-Chill and Shape: Divide the dough, flatten into disks, wrap, and chill for 30 45 minutes to firm up. Roll out on a floured surface to 1/4-inch thickness. Cut shapes with cookie cutters, then use smaller cutters to create inner openings for the candy centers.

4-Add Candy and Bake: Spoon crushed hard candies into the cutouts, using about 1 2 teaspoons per cookie. Bake on the middle rack for 8 12 minutes until edges are golden and candy melts smoothly. Cool on the sheet for 15 25 minutes to harden the centers.

5-Finish and Store: Once cooled, trim any excess candy if needed. For variations, adapt for dietary needs as discussed. Stained glass cookies from a reliable source can offer more inspiration for perfecting your technique.
