Add in your sprinkles and pour into an 8×8 pan.
Top with more sprinkles and store in the fridge for 2 hours to set before slicing and serving.
Storing Fudge
Your fudge needs to have that chill factor to help harden it up some, so it just doesn’t fall apart. Once you have it set up in the fridge, slice, serve or save.
You can then leave your fudge at room temperature or place it back in the fridge. It is all about preference. Make sure to use an air-tight container in whichever storage method you prefer.
Can You Freeze Fudge
We freeze fudge often, because it is rich, and with just our son and we eating it, it would go bad before we got it all eaten. So, just wrap up your fudge once made in aluminum foil. Then place the foil-wrapped fudge in a resealable freezer bag or freezer container, and freeze up to 3 months.Thaw in the fridge or on the counter when you are ready to eat it. We always pre-slice it, so we can pull out a piece here and there to enjoy, and then toss the rest back in the freezer.

Kitchen notes
Heating FlourIt is important to cook your flour. Otherwise, you can get sick eating the fudge without treating the flour. Sprinkles You are welcome to use any brand or style of sprinkles you want. Some brands of sprinkles we have found do break down a bit and bleed. Others seem to hold up well. So just watch the style you use, and fingers crossed they work well. Pan We recommend lining your pan with parchment paper or wax paper. This will help prevent your fudge from sticking into the pan. Freezing Fudge You can freeze your fudge if you don't want eat it all right away. Freeze in an airtight container for 3-4 months.
