I appreciate how unbelievably easy this fudge is to make with only two ingredients and almost no preparation time. The texture turns out soft, creamy, and perfectly sweet every time.

Ingredients

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

peanut butter
vanilla frosting

Directions

I start by lining a small baking dish or container with parchment paper.
In a microwave-safe bowl, I combine the peanut butter and vanilla frosting.
I microwave the mixture in short intervals, stirring after each one, until everything becomes smooth and fully combined.
I pour the mixture into the prepared dish and spread it evenly with a spatula.
I refrigerate the fudge for about 2 hours, or until fully firm.
Once set, I cut the fudge into small squares and serve chilled or at room temperature.

Prep Time: 10 minutes
Chill Time: 2 hours
Total Time: 2 hours 10 minutes

Variations

I sometimes stir chocolate chips into the mixture for extra richness. When I want a crunchier texture, I use chunky peanut butter instead of creamy. I also enjoy topping the fudge with crushed peanuts, sea salt, or melted chocolate drizzle. For a different flavor, I occasionally swap peanut butter with almond butter or cookie butter. If I want a sweeter dessert, I mix in mini marshmallows or crushed cookies.

storage/reheating

I store the fudge in an airtight container in the refrigerator for up to 1 week. I like keeping parchment paper between layers so the pieces do not stick together. This fudge can also be frozen for up to 2 months. Since it is meant to be served chilled or at room temperature, I do not reheat it.

FAQs

Can I use natural peanut butter?

I prefer regular creamy peanut butter because natural peanut butter can sometimes make the texture oily or less firm.

Do I need to use store-bought frosting?

I usually use store-bought vanilla frosting for convenience, but homemade frosting can also work if it has a smooth consistency.

How do I know when the fudge is set?

I check that the fudge feels firm to the touch and slices cleanly after chilling.

Can I make this fudge in advance?

I often prepare it a day ahead because it stores very well in the refrigerator.

Can I add chocolate to this recipe?

I sometimes drizzle melted chocolate over the top or mix chocolate chips into the fudge for extra flavor.
