Prepare a baking sheet by turning it upside down and placing a sil pat or piece of parchment paper atop the "bottom" of the sheet. Pour 1 tablespoon of batter onto the baking sheet and gently use the back of the measuring spoon to swirl from the center and push outward to form a 4 inch circle. Add up to 4 total cookies per batch.
Bake for 9 minutes at 375 degrees until the edges of the cookies are just turning golden.
Remove from the oven and add the next batch. Immediately slide an offset spatula under a cookie to release it. Flip it upside down in your hand and add the fortune to the center. Bring the edges together like a taco shell.
Place the rounded bottom onto the edge of a glass. Gently use your fingers along the seam you created to push down and fold the fortune cookie over the glass rim to shape it. Please into a muffin tin to retain the shape until the cookie cools.
Repeat with the remaining baked cookies. All will harden in under a minute.
Store in an airtight container on the counter for 4-5 days, max.
