This white chocolate fudge has become my secret weapon for impressing guests with minimal effort. Bursting with sweet vanilla flavor and colorful sprinkles, it transforms any ordinary day into a celebration with just 15 minutes of hands-on time.
I first made this fudge for my daughter's birthday when I realized I'd forgotten to order a cake. The panic quickly turned to triumph when everyone requested the recipe instead of asking about the missing cake!
Ingredients
- Sweetened condensed milk: Provides the creamy base and perfect sweetness. Be certain not to accidentally grab evaporated milk.
- White chocolate chips: Create that melt in your mouth texture. Ghirardelli brand offers superior meltability and flavor.
- Salted butter: Balances the sweetness while adding richness. The salt element is crucial here.
- Funfetti cake mix: Transforms this from ordinary fudge to something magical with minimal effort.
- Vanilla extract: Enhances the cake flavor profile. Use pure extract for best results.
- Colorful sprinkles: Bring the fun factor and festive appearance. Choose jimmies rather than nonpareils as they won't bleed into the fudge.
Step-by-Step Instructions
- Line the Pan:
- Start with an 8x8 pan lined completely with parchment paper. Ensure paper extends up the sides for easy removal. This step sounds simple but is crucial for clean cuts later.
- Create the Base:
- Combine condensed milk, white chocolate chips and butter in a medium saucepan over medium heat. Stir constantly to prevent scorching. The mixture will become smooth and glossy after about 5 minutes when properly melted.
- Add Flavor Elements:
- Reduce heat to low before incorporating the dry cake mix and vanilla. This prevents burning while the dry ingredients absorb into the mixture. Stir vigorously until no dry specks remain, usually about 2 minutes of continuous stirring.
- Finish and Set:
- Remove from heat and quickly fold in sprinkles. Work fast as the mixture begins setting rapidly. Pour immediately into prepared pan and smooth the top with a spatula. Add additional sprinkles on top before the surface sets for a professional bakery appearance.
- Chill Properly:
- Allow to cool at room temperature before refrigerating for at least 6 hours. Patience is key. Rushing this step results in soft fudge that won't hold its shape when cut.

The funfetti cake mix completely transforms this fudge from just another white chocolate variety to something uniquely special. My nephew once declared it tastes like birthday cake in fudge form, which perfectly captures what makes this recipe a standout in my collection of treats.
Storage Tips
This fudge stays fresh in an airtight container in the refrigerator for up to two weeks. For best results, separate layers with parchment paper to prevent sticking. You can also freeze individual pieces wrapped tightly in plastic wrap and stored in a freezer bag for up to three months. Allow frozen pieces to thaw overnight in the refrigerator before serving.
Flavor Variations
Experiment with different cake mix flavors to completely transform this recipe. Chocolate, strawberry, or lemon cake mix creates entirely different fudge experiences while following the exact same method. You can also swap the vanilla extract for other flavors like almond, coconut, or even peppermint extract during holiday seasons for a customized treat.
Serving Suggestions
While delicious on its own, this fudge elevates to new heights when served alongside vanilla ice cream. The contrast between cold ice cream and sweet fudge creates a dessert worthy of company. For an elegant presentation, cut into tiny squares and arrange on a platter with fresh berries and mint leaves for a beautiful dessert board.
