I am using a recipe taken from this Recipe for Butterscotch Pie recipe. I will post a picture below as well.
The main ingredients for the pie are 2 3.4 ounce instant butterscotch pudding mixes with 12 ounces of cool whip and 2 cups of milk. After combining the ingredients, and half of the cool whip, my butterscotch filling turns into a runny mess rather than a fluffy filling. Even after putting in the fridge for a couple of days, it does not set at all.
