01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper and set aside.
02 - Open the Earl Grey tea bags and finely grind the contents into a powder using a mortar and pestle or spice grinder.
03 - In a medium bowl, whisk together the gluten-free flour, almond flour, ground Earl Grey tea, baking powder, and salt until thoroughly combined.
04 - In a large bowl, beat the vegan butter and granulated sugar together until light and fluffy. 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, cohesive dough forms. If the dough is too sticky to handle, refrigerate for 15 minutes.
06 - Lightly dust a clean surface with gluten-free flour. Roll out the dough to 1/4 inch thickness. Use a large cookie cutter to cut out shapes, then use a small cutter to remove the center from each cookie, creating a window.
07 - Transfer the cut cookies to the prepared baking sheets. Fill each cut-out center with 1-2 teaspoons of crushed vegan candy. Gently press a few edible flower petals into the candy so they adhere.
08 - Bake for 9-11 minutes, until the edges are lightly golden and the candy centers have completely melted into a translucent glass-like finish.
09 - Allow the cookies to cool completely on the baking sheet. The stained glass centers will harden as they cool, becoming firm and glossy.
