To prepare a teenies accidental rhubarb raspberry pie recipe, first you need to gather your ingredients. First, you will need the following ingredients: 1/2 cup sugar, 1/4 cup granulated sugar and 1/4 teaspoon vanilla extract. You will also need: 1 cup butter, 1 tablespoon of melted butter and 1 teaspoon of salt. If you don't have any of these ingredients, then you can use butter or margarine instead of the sugar. Mix the ingredients together until they are well combined. Pour the mixture into an ungreased pie shell and bake in the oven for 30 minutes or until the crust is golden brown and the filling is bubbly. Allow the pie to cool for 10 minutes before serving.
