01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - Open the Earl Grey tea bags and finely grind the contents if using loose leaves.
03 - In a medium bowl, whisk together the gluten-free flour, almond flour, ground Earl Grey tea, baking powder, and salt.
04 - In a large bowl, cream together the vegan butter and sugar until fluffy. Add plant milk, maple syrup, and vanilla extract, and mix well.
05 - Gradually add the dry ingredients to the wet, mixing until a soft dough forms. If too sticky, chill for 15 minutes.
06 - Lightly flour a surface with gluten-free flour. Roll out the dough to about 1/4 inch thickness.
07 - Use a large cookie cutter for the outer shape and a small cutter to create a window in the center. Transfer the cut cookies to the prepared trays.
08 - Fill the cut-out centers with 1–2 teaspoons crushed vegan candy. Sprinkle with a few edible flowers, pressing gently so they adhere to the candy.
09 - Bake for 9–11 minutes, until edges are just golden and candy centers have melted.
10 - Allow cookies to cool fully on the tray before transferring, as the stained glass will harden as they cool.
