True to its name, this recipe only uses 2 ingredients. Better yet they are also pantry staples.
- Frosting- Use vanilla flavored store bought frosting. Do not use cream cheese or whipped frosting. When recipe testing we tried both different variations of frostings like cream cheese and whipped and they were not as good. You could also use chocolate frosting, we found that the flavor of the frosting could be changed without any problems.
- Peanut Butter- Use creamy peanut butter. Do not use natural peanut butter, it's too runny and the results will vary. All jars are different but try to use between 16-18 ounces.

- Add the vanilla frosting and the peanut butter into a microwave-safe bow.
2. Microwave the 2 ingredients together at small intervals. You don't want to microwave too long or it will ruin the ingredients.
3. Once the peanut butter and vanilla frosting are warm mix, together until a smooth mixture is formed.
4. Spread the 2 ingredient fudge mixture in a prepared 9x9 or 8x8 pan lined with parchment paper. The smaller the pan the thicker the fudge will be.
Hint: It's helpful to use parchment paper at the bottom of the pan for easiest removal of the fudge.
We love switching things up when we're in the kitchen. Try any of these variations for something a little different.
- Natural Peanut Butter- You may be tempted to use natural peanut butter because of its health benefits. You can but know that the results will vary and the fudge may not set like you want it to.
- Crunchy Peanut Butter- If you want to add some nuts but want to stick with the 2 ingredient theme, use crunchy peanut butter! It adds chopped peanuts throughout the fudge.
- Chocolate Frosting- For a chocolate peanut butter experience, use chocolate frosting instead of vanilla.
Don't overcook the peanut butter and frosting! Worst case scenario, you could burn it and it would have a burnt taste to it, or you might over cook it so much that it makes it gritty when it cools. You want it soft enough to be able to mix the peanut butter in, so after the first initial time in the microwave, just use 10-15 second increments until the desired texture is achieved.
How To Serve
This is a great neighbor gift during the holidays. Add it to a plate of cookies, or give the dessert on its own. Be sure to let the recipient know that if it's not eaten right away it needs to be refrigerated and not left on the counter.

We make this every Christmas season, but the first time I ever made this, I was so worried about overcooking it that I didn't warm up the ingredients quite enough and they were hard to mix. If your fudge is hard to mix and the peanut butter is not mixing in, try giving it another 15 seconds in the microwave.
One time when making this fudge, I took it to a party. It sat out for about 2 hours before being served and by the time it was time to eat it, it was very soft and a little droopy. It was still delicious and everyone loved it, but now I make sure to refrigerate it until I'm ready to serve.
Storing Peanut Butter Fudge
Store the 2 ingredient peanut butter fudge in the refrigerator for 1 week in the refrigerator. If you serve it cold it will have a better texture.
You can absolutely freeze this recipe. Cut it into squares and put it in a freezer-friendly container. Freeze for up to 2 months. Remove and enjoy frozen, or thaw in the refrigerator. The texture may vary slightly.
Don't let the fudge stay at room temperature for too long. It will start to get soft and less fudge-like.
