Step-by-Step Instructions
- Prepare the Pan
- Line a 9x9-inch baking pan with parchment paper, leaving an overhang for easy removal.

- Mix White Fudge
- Remove saucepan from heat. Stir in white chocolate chips, marshmallow crème, and vanilla until completely smooth.

- Microwave semi-sweet chocolate chips in 20-second intervals, stirring until melted. Mix in red food coloring for an even color.

Pro Tips for Success
Through lots of trial and error I've found that using really good quality white chocolate makes such a difference in the texture. I keep my knife clean between swirls to keep those red patterns looking sharp and beautiful. And that gel food coloring? It's worth seeking out for the most vibrant red you can imagine.
Serving Suggestions
I love arranging these little squares on my grandmother's silver platter for parties they look like jewels. For gifting I'll package them in pretty boxes lined with wax paper sometimes adding a sprinkle of edible glitter on top for extra sparkle. They're always the first thing to disappear from holiday dessert tables.
Storage and Make-Ahead Tips
When I'm planning ahead for the holidays I'll make several batches and freeze them. They keep beautifully wrapped in plastic and foil just remember to let them thaw slowly in the fridge. At room temperature they'll stay fresh for about a week but honestly they rarely last that long in my house.
Customization Ideas
Sometimes I'll switch things up using different chocolate combinations or adding crushed peppermint during the holidays. My kids love helping create new color combinations for different celebrations pink for Valentine's Day green for St. Patrick's Day. The possibilities are endless.

- → How do I store this fudge?
- Store in an airtight container at room temperature for up to 2 weeks, or refrigerate for up to 3 weeks. Layer pieces with wax paper to prevent sticking.
- → Can I freeze this fudge?

- → Why didn't my swirls turn out?
- Work quickly when creating swirls as the fudge starts setting fast. Don't overmix or the colors will blend together instead of creating distinct swirls.
- → Can I use milk chocolate instead of semi-sweet?
