This slow cooker 4-ingredient mango margarita fudge is the kind of easy summer treat that feels a little special without making a mess of your whole kitchen. It has that bright, tropical mango flavor with a little lime-inspired tang that makes it taste like a warm-weather dessert table favorite, and the slow cooker does most of the work for you. I love recipes like this for parties, cookouts, and family get-togethers because you can make it ahead, chill it, and cut it into neat little squares when you are ready to serve.
Serve this fudge well chilled on a dessert tray with fresh fruit, coconut macaroons, or buttery shortbread cookies. For summer gatherings, it fits right in alongside lemonade, iced tea, or sparkling water with lime, and if you are putting together a party spread, it also pairs nicely with grilled foods since the sweet-tart flavor is such a refreshing finish.
Slow Cooker 4-Ingredient Mango Margarita Fudge
Servings: 25 small squares
Ingredients
3 cups white chocolate chips
1 can (14 ounces) sweetened condensed milk
1 cup mango curd or thick mango puree
1 tablespoon lime zest
Directions
1. Line an 8-inch square pan or small baking dish with foil or parchment, leaving a little overhang so the fudge is easy to lift out later. Lightly grease the lining if needed.
2. Add the white chocolate chips, sweetened condensed milk, and mango curd or thick mango puree to the slow cooker. Cover and cook on low for 30 to 45 minutes, stirring every 10 to 15 minutes, until the mixture is melted and smooth.
3. Stir in the lime zest and mix just until evenly combined. If you want a swirled look, reserve a spoonful of mango puree and gently swirl it in at the end instead of fully mixing.
4. Spread the mixture into the prepared pan and smooth the top. For a pretty finish, add a little extra lime zest over the top and a tiny pinch of coarse sea salt if you like that sweet-salty contrast.
5. Refrigerate for 3 to 4 hours, or until fully set. Lift the fudge from the pan, cut into small squares, and serve chilled.
Variations & Tips
For picky eaters: Leave off the sea salt on top if your family prefers a straightforward sweet treat. The mango and white chocolate are still plenty flavorful on their own.
For cleaner slices: Chill the fudge thoroughly and use a sharp knife wiped clean between cuts. That little step makes the squares look much neater on a party tray.
For a stronger citrus flavor: Add a bit more lime zest, but keep it to zest rather than extra juice so the fudge stays thick and sets properly.
For easy slow cooker success: Every slow cooker heats a little differently, so stir often and stop cooking as soon as the chocolate is melted. Overheating can make white chocolate grainy.
For a tropical twist: Sprinkle a little unsweetened toasted coconut over the top before chilling for a fun variation that feels right at home at summer parties.
