Chill the shaped dough in the muffin tin for 10 minutes before baking if your kitchen is warm to help the cups keep their shape. If the cups puff too much, repress with a glass as soon as they come out of the oven. Let the cookie cups cool completely so the ice cream doesn’t melt on contact and cause leaks. Use mini chocolate chips for a smoother cup interior that’s easier to press. For sturdier cups, replace 2 tablespoons of butter with 2 tablespoons of milk or dark chocolate melted and cooled, or add 1 tablespoon cornstarch to the dry ingredients. You can bake the cups a day ahead and store them airtight; assemble the floats just before serving for the best fizz and texture.
