Get a jump on dessert—use Kellogg’s® Eggo® waffles to make tart shells for this easy key lime filling.
1. Microwave waffles, one at a time, at high for 15 to 20 seconds or until pliable. Using rolling pin, flatten waffles into 4 3/4-inch circles. Firmly press into eight 10-ounce custard cups or 4-inch tart pans coated with cooking spray. Place custard cups on baking sheet. Bake at 350° F for 10 minutes. Carefully remove waffles from cups. Place waffle shells upside down on baking sheet. Bake at 350° F about 5 minutes more or until crisp. Cool completely.
2. Meanwhile, in medium bowl beat egg yolks with wire whisk until combined. Gradually whisk in condensed milk. Add lime juice, lime peel and food coloring (if desired). Mix well (mixture will thicken slightly).
3. Arrange tart shells right side up on baking sheet. Spoon lime mixture into tart shells. Bake at 350° for 7 to 10 minutes or until set. Cool on wire rack for 1 hour. Refrigerate for 30 minutes. Serve with whipped topping and lime slices (if desired).
