So the Banana's science project is to find out if kids can tell the difference between sugar vs. sugar substitute. We used Truvia baking- specifically meant for baking cookies, etc... Once I made Chocolate Chip cookies with it and no one could tell.
3/4 cup shortening (or part butter or margarine)
1 cup sugar (and in our case 1/2 cup of truvia baking)
2 eggs, room temperature
1 teaspoon vanilla
2 1/2 cups all-purpose flour
1 teaspoon baking powder
1 teaspoon salt
