Why Make This

  • Two main ingredients and a microwave make this fudge kid-friendly and easy.
  • Just 10 minutes of prep delivers creamy, nostalgic peanut butter fudge at home.
  • You can dress the fudge up with melted chocolate or chopped peanuts for variety.

I have very fond memories of making rich, creamy peanut butter fudge with my grandmother, though I don’t quite remember the recipe. I do know that it used minimal ingredients and the microwave. It was the perfect candy recipe for me to make as a kid—there was no need for a thermometer or any risks of working with hot sugar.

I was recently inspired by TikTok to revisit making peanut butter fudge in the microwave. This version required just two ingredients: creamy peanut butter and canned frosting. Plus, it seemed like an ideal way to impress my teen daughter (a TikTok treat? Yes, please!).

My daughter and I fiddled around a bit with the technique and proportions to find a recipe that takes less than 10 minutes to prepare, chills for just an hour, and makes a super creamy peanut butter fudge. You can enjoy it straight from the fridge or dress it up with a drizzle of melted chocolate or a shower of chopped peanuts.

The Key Ingredients

You’ll need one (15-ounce) container of no-stir creamy peanut butter and one (16-ounce) container of vanilla frosting. While you can customize your fudge by adding chopped nuts or trying another flavor of frosting, I recommend sticking to a creamy, no-stir brand peanut butter. Jif, Skippy, and Peter Pan all work. 

As long as you stick to the same proportions and creamy peanut butter, you can get a little playful with the frosting. Try French vanilla or cream cheese frosting, but skip any whipped varieties.

Keep Screen Awake

Ingredients

  • 1 (16-ounce) container frosting (vanilla or cream cheese are favorites), about 2 cups

  • 1 (15-ounce) container no-stir creamy peanut butter, such as Jif or Skippy, about 2 cups

Method

  1. Prepare the pan:

    Line an 8 x 8-inch square baking dish with parchment paper.

  2. Combine frosting and peanut butter:

    Combine the frosting and peanut butter in a medium microwave-safe bowl. Don’t worry about mixing them together yet. Microwave on high for 30 seconds, stir with a spatula, and microwave again for 30 seconds. Mix again until completely smooth.

  3. Pour into the pan and refrigerate:

    Pour into the prepared pan. You can press some chopped peanuts or peanut butter cups into the top or drizzle with melted chocolate if you like. Refrigerate for at least 1 hour to set. Use the parchment to remove from the pan and cut into 24 pieces to serve. Store in an air-tight container in the fridge for up to a week.
