Spoon 1 Tbsp measurements of batter onto the greased baking sheet (leaving a small space in between cakies) and spread around and flatten a bit - you don't want mounds, but rather discs.
Bake for 10 minutes. Remove from oven, let set on tray for 5 minutes, then carefully transfer to a cooling rack to cool. Once cooled, pop cakies in the freezer to harden so they're easier to work with.
Once soft, use an ice cream scoop to scoop out 8 large balls of ice cream onto squares of plastic wrap (amount as original recipe is written // adjust if altering batch size). Fold the plastic wrap around the balls and squash them into thick discs. Twist off tops to cover and place back in the freezer to harden - about 30 minutes.
*IMPORTANT: Before eating, either let your sandwich set out for about 15 minutes OR unwrap it and microwave on a plate for 20 seconds. The more frozen it is, the less you can taste its flavors.
*These would be excellent dipped in dark chocolate and/or rolled in nuts before serving.
