Some recipes earn a permanent spot in the kitchen because they solve dessert emergencies fast, and this one absolutely fits that category. It is the kind of old-school, no-bake treat that feels right at home at potlucks, holiday cookie trays, and weeknight cravings, especially when you need something sweet without hauling out a mixer or turning on the oven. I love keeping simple recipes like this around for busy workweeks because they come together with almost no prep and somehow still taste like the kind of treat someone made with extra care.
Serve this rich, sweet treat in small squares with hot coffee, cold milk, or a cup of black tea to balance the sweetness. It also works well on a dessert platter with pretzels, chocolate-covered nuts, or fresh strawberries for a little contrast, and if you're bringing it to a gathering, a chilled pan sliced into neat bites travels especially well.
2-Ingredient Peanut Butter Fudge
Servings: 16 squares
Ingredients
1 can (16 oz) vanilla frosting
1 cup creamy peanut butter
Directions
1. Lightly grease a small glass or ceramic baking dish, or line it with parchment paper for easier lifting and slicing later.
2. Add the vanilla frosting and creamy peanut butter to a medium microwave-safe bowl.
3. Microwave the mixture in 30-second intervals, stirring well after each one, until smooth and fully combined.
4. Pour the mixture into the prepared dish and spread it into an even layer.
5. Refrigerate for 2 to 3 hours, or until firm enough to cut cleanly into squares.
6. Slice into squares and serve chilled or at cool room temperature.
Variations & Tips
For cleaner slices: Chill the pan thoroughly and use a sharp knife wiped clean between cuts. If I am making these ahead for a gathering, I like to line the dish with parchment so I can lift the whole slab out before slicing.
Microwave timing: Every microwave runs a little differently, so heat gently and stir often. You want the mixture just warm enough to become smooth, not bubbling or overheated, which can make the texture less silky.
Texture adjustment: If you prefer a slightly softer bite, let the squares sit at room temperature for a few minutes before serving. For a firmer, candy-shop style texture, keep them chilled until right before eating.
Easy add-ins: Even though the base recipe is wonderfully simple, you can stir in a small handful of chopped salted peanuts for crunch or add a light sprinkle of flaky salt on top before chilling to balance the sweetness.
