2-Ingredient Peanut Butter Fudge

Why You’ll Love This Recipe

I enjoy this recipe because it requires only two simple ingredients that are easy to find. I can prepare it in just a few minutes, and the refrigerator does the rest of the work. The texture turns out perfectly creamy, and the sweet peanut butter flavor makes it a crowd-pleaser for holidays, parties, or everyday treats. I also appreciate how easy it is to customize with different toppings or mix-ins.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• 18 oz creamy peanut butter
• 16 oz vanilla frosting

Directions

1. I line a 9×9-inch or 8×8-inch square pan with parchment paper and set it aside.
2. I combine the peanut butter and vanilla frosting in a microwave-safe bowl.
3. I microwave the mixture for 30 seconds and stir well. Then I return it to the microwave for another 30 seconds and stir until smooth.
4. I transfer the mixture into the prepared pan and use an offset spatula to spread it into an even layer.
5. I refrigerate the fudge for about 2 hours or until fully set.
6. I slice it into bite-sized squares and serve.

Servings and Timing

• Servings: 36 pieces
• Prep Time: 5 minutes
• Chill Time: 2 hours
• Total Time: 2 hours 5 minutes

Variations

I sometimes add chocolate chips to the mixture for extra richness. Chopped peanuts create a pleasant crunch and enhance the peanut flavor. When I want a festive version, I sprinkle colorful candies or holiday-themed sprinkles on top before chilling. I can also drizzle melted chocolate over the finished fudge for a decorative touch.

Storage/Reheating

I store the fudge in an airtight container in the refrigerator for up to one week. For longer storage, I place the pieces in a freezer-safe container and freeze them for up to three months. When I am ready to enjoy frozen fudge, I let it thaw in the refrigerator for several hours. Since fudge is served chilled or at room temperature, reheating is not necessary.

FAQs

Can I use crunchy peanut butter instead of creamy?

I can substitute crunchy peanut butter if I prefer a little texture in the finished fudge. The flavor remains just as delicious.

Do I need to use a microwave?

I can also melt the ingredients together on the stovetop over low heat, stirring frequently until smooth.

How do I know when the fudge is fully set?

I check that the surface feels firm and the fudge holds its shape when sliced. This usually takes about two hours in the refrigerator.

Can I make this fudge ahead of time?

I often prepare it a day or two in advance since it stores well and maintains its texture.

Can I add other flavors?

I like experimenting with vanilla extract, chocolate chips, chopped nuts, or even a drizzle of caramel for different flavor combinations.
