Tricks For The Best Results
Go for good white chocolate since it melts better. Get everything measured out before you start cooking. Don't dawdle when adding chocolate and making swirls because the mix hardens fast. Try gel food coloring for the brightest red. Wipe your tool clean between swirls to keep patterns sharp.

Ways To Enjoy It
Slice into small 1-inch squares for the right size. Put them on pretty plates for holiday gatherings. Wrap them in wax paper and pack in boxes for gifts. You can also drizzle extra melted white chocolate on top before serving. They're wonderful on dessert spreads or alongside cookies.
Keeping It Fresh
Keep in a sealed container at room temp for up to a week. Put wax paper between layers so they don't stick together. You can freeze it for up to 3 months if you wrap it tight in plastic and foil. Thaw in your fridge overnight when you want some. Let it warm up to room temperature for the best taste and feel.
Frequently Asked Questions
- → What makes marshmallow creme special?
It keeps the fudge creamy and prevents it from turning gritty or hardening with sugar crystals.
- → What's the best way to store it?
Keep it in a sealed container at room temperature for up to two weeks, or refrigerate for longer. Layer pieces with wax paper so they don't stick.
- → Can milk chocolate work instead of semi-sweet?
You can use it, although semi-sweet contrasts more with white chocolate and balances the sweetness better.
- → Why use parchment paper?
Lining the pan with parchment helps lift the fudge out easily for neat slicing and avoids sticking problems.
- → Tips for a perfect swirl?
Move fast while the mix is warm, and gently swirl with a knife. Stop before colors blend too much to keep the pattern sharp.
