This cake batter fudge is the kind of candy that looks special without requiring a candy thermometer, stovetop simmering, or a long ingredient list. The microwave does the melting work, and the finished mixture only needs time in the refrigerator before it is ready to slice.
The flavor is sweet and creamy, with white chocolate bringing richness and dry cake mix supplying the classic birthday-cake taste. Because the pieces are small and dense, one batch makes approximately 25–36 squares, depending on how generously you cut them.
It is also easy to customize for birthdays, baby showers, classroom celebrations, Christmas cookie trays, and colorful dessert tables. Choose yellow cake mix for a buttery cake flavor or white cake mix for a lighter vanilla profile.

Ingredients You’ll Need
The three essential ingredients are white chocolate chips, sweetened condensed milk, and dry cake mix. Use exactly 1 cup of cake mix, which is approximately 120–130 grams; do not pour an entire standard cake-mix box into the bowl.
- White chocolate chips: Use 2 cups, or 12 ounces/340 grams. They create the creamy base and mellow sweetness of the fudge.
- Sweetened condensed milk: One 14-ounce can, or 396 grams, supplies moisture and sweetness while helping the mixture become firm after chilling.
- Dry cake mix: Measure 1 cup of yellow or white mix. Sifting it before use helps reduce lumps and makes the batter flavor blend more evenly.
- Colorful sprinkles: Add 2–4 tablespoons if desired. Sprinkles can be stirred into the fudge, scattered over the top, or used in both places.
Be sure to use sweetened condensed milk rather than evaporated milk. They are not interchangeable in this recipe: evaporated milk does not provide the same sweetness or texture needed for this no-bake fudge.
How to Make It Step-by-Step
Step 1: Line an 8-inch square baking pan with parchment paper or foil, leaving some overhang along the sides. The overhang acts like a handle, making it easy to lift the solid fudge from the pan without digging into the corners.
Step 2: Heat-treat the measured cake mix before adding it to the fudge. Place the 1 cup of dry mix in a shallow microwave-safe bowl and microwave it in short intervals, stirring after each interval, until it reaches 165°F/74°C; allow it to cool before continuing.
Step 3: Put the white chocolate chips and sweetened condensed milk in a microwave-safe bowl. Microwave the mixture for 60 seconds, then remove it and stir thoroughly, even if some chips still appear intact.
Step 4: Return the bowl to the microwave and continue heating in 15–30-second intervals. Stir after every interval and stop as soon as the mixture becomes smooth, since excessive heat can cause white chocolate to seize or become thick and grainy.
Step 5: Sift the cooled cake mix directly into the melted chocolate mixture. Stir patiently until no dry pockets remain and the mixture has a thick, even appearance.
Step 6: Fold in 2–4 tablespoons of sprinkles if you want color throughout the candy. Use a gentle motion so the sprinkles stay bright and do not dissolve into the warm mixture.
Step 7: Scrape the fudge into the lined pan and spread it into an even layer. Add a few extra sprinkles on top, pressing them very lightly into the surface so they stay in place after chilling.
Step 8: Refrigerate the pan for at least 2 hours, or until the fudge feels firm when lightly touched. Lift it out using the parchment or foil overhang, place it on a cutting board, and slice it into small squares.
Pro Tips for Smooth, Creamy Fudge
The most important technique is gentle heating. White chocolate can scorch more easily than dark or semisweet chocolate, so short microwave intervals and frequent stirring are better than one long burst of heat.
Sifting the cake mix is worth the extra minute. Dry mix can contain compacted pockets, and breaking them up first gives the fudge a smoother finish with fewer pale lumps.
Let the heat-treated cake mix cool before stirring it into the melted chocolate. Adding hot dry mix can change the consistency of the fudge and may make it harder to judge whether the chocolate mixture is properly melted.
For clean cuts, chill the fudge fully and use a sharp knife. If the knife drags, warm the blade under hot water, dry it carefully, and then make the next cut; repeat as needed for tidy squares.
Keep the pieces small because this candy is rich. A ruler can help you create uniform squares, but a casual hand-cut batch is just as inviting for a family dessert tray.
Flavor Variations and Serving Ideas
Yellow cake mix gives the fudge a warm, buttery cake flavor, while white cake mix creates a simple vanilla base that pairs beautifully with nearly any sprinkle color. For a party, match the sprinkles to the event instead of changing the three core ingredients.
Try pastel sprinkles for a spring gathering, red and green for a holiday plate, or school colors for a team celebration. Add the decorations while the surface is still soft so they adhere without needing frosting or extra melted chocolate.
Serve the squares chilled for the firmest bite, or let them sit at room temperature briefly for a softer, creamier texture. They look lovely arranged in mini paper candy cups beside cookies, cupcakes, or fruit.
For another cheerful dessert idea, pair this fudge with our patriotic dump cake at a summer celebration. A bright dessert spread can also include these refreshing lime bars for a tangy contrast to the sweet fudge.
Storage, Chilling, and Make-Ahead Notes
Refrigerate the fudge for at least 2 hours before cutting, since chilling is what allows the mixture to become firm enough to handle. If your kitchen is warm, keeping the candy chilled until shortly before serving will help preserve its shape.
Store the squares in an airtight container in the refrigerator, arranging layers with parchment paper between them if necessary. The pieces are convenient to make ahead for parties because they can be cut and plated shortly before guests arrive.
When transporting the candy, use a firm, flat container and keep it cool. Avoid leaving it in direct sunlight or near a warm oven, as the white chocolate base can soften.
For a full candy assortment, add a batch of stovetop caramel apples alongside the fudge. The chewy caramel and crisp apple offer a different texture while keeping the dessert table playful and homemade.
