Place ramekins upside down on a baking sheet. Cover with the tortillas. Gently push down on the sides to shape the tortilla around the ramekin.
Tear off 2 8" x 16" pieces of foil. Fold in half to form an 8" x 8" rectangle. Place on top of the tortilla and press down all sides. The foil will keep the tortilla shaped like a bowl.
Flip over the ramekins. Transfer to the oven and bake for 5 minutes.
Carefully remove the ramekins from the bowls. Bake for 5 more minutes.
Remove the tortilla from the foil.
Carefully remove tortilla from foil. Flatten out the foil and place bowl on top. Bake another 8-10 minutes or until browned and crispy.
Flip bowls upright and bake another 3-5 minutes.
Remove to a wire rack to let cool to room temperature. Bowls will become crispy as they cool.
