01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper to prevent sticking.
02 - Open the Earl Grey tea bags and finely grind the contents if using loose leaf tea to release the aromatic oils.
03 - In a medium bowl, whisk together the gluten-free flour, almond flour, ground Earl Grey tea, baking powder, and salt until evenly distributed.
04 - In a large bowl, cream together the vegan butter and sugar until fluffy and light. Add the plant milk, maple syrup, and vanilla extract, mixing well to incorporate.
05 - Gradually add the dry ingredients to the wet mixture, mixing until a soft dough forms. If the dough becomes too sticky to handle, refrigerate for 15 minutes.
06 - Lightly flour a clean surface with gluten-free flour. Roll out the dough to approximately 1/4 inch thickness for even baking.
07 - Use a large cookie cutter for the outer shape and a smaller cutter to create a window in the center of each cookie. Transfer the cut cookies carefully to the prepared baking trays.
08 - Fill the cut-out centers with 1 to 2 teaspoons of crushed vegan candy. Sprinkle a few edible flowers on top, pressing gently so they adhere to the candy pieces.
09 - Bake for 9 to 11 minutes, or until the edges are just beginning to turn golden and the candy centers have completely melted into a translucent glass effect.
10 - Allow the cookies to cool fully on the baking tray before attempting to move them. The stained glass centers will harden as they cool, creating a stable finished product.
