Preheat the oven to 400°F (204°C). Lightly spray a baking sheet with non-stick spray, ensuring it is broiler-safe.

In a large mixing bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, cinnamon, cardamom, and salt. Cut the cold butter into the dry mixture until it resembles coarse crumbs.
03 -
In a separate bowl, whisk milk, egg, and vanilla extract. Add the wet ingredients to the dry mixture and stir gently until just combined. Fold in the chopped rhubarb carefully.

Spoon heaping ¼-cup portions of batter onto the prepared baking sheet. Bake for 11 to 13 minutes or until the bottoms are golden brown and centers are set (start checking at 8 minutes for smaller fritters). Transfer to a wire rack and reduce the oven to broil.
05 -
Whisk the confectioners’ sugar, 2 tablespoons of milk, and vanilla extract until smooth. Brush a thin layer of glaze over the baked fritters.
06 -
Place the fritters under the broiler for 2 to 4 minutes, until the tops begin to turn golden and the glaze bubbles. Remove carefully to a wire rack.
07 -
Stir the remaining ½ teaspoon milk into the leftover glaze. Brush this remaining glaze over the warm fritters. Allow to set before serving.
