Ice cream has always been a staple dessert in our family and during the summer months our freezer is stocked. So stocked that every time I open the freezer, ice cream falls out. Maxwell giggles every time it happens because I scream. I guess the saying is true, “I scream, you scream, we all scream for ice cream!

I also keep a lot of yummy toppings on hand to go with our ice cream. Some of our favorites include: sprinkles, nuts, chocolate chips, fruit, chopped up candy bars, salted caramel sauce, and hot fudge.

My current obsession is this 3-Ingredient Peanut Butter Hot Fudge. It is the BEST ice cream topping!

  • 1 1/2 cups semi-sweet chocolate chips
  • 1 can 14 oz sweetened condensed milk
  • 1/3 cup creamy peanut butter


  • In a microwave-safe bowl, combine the chocolate chips, sweetened condensed milk, and peanut butter. Microwave for 1 minute. Remove from microwave and stir until hot fudge sauce is creamy and smooth. If the sauce is still a little lumpy, microwave for 15 more seconds. Remove from the microwave and stir again. The sauce will be thick. If it is too thick for your liking, you can add 2 tablespoons of hot water. Serve the hot fudge warm over ice cream, frozen yogurt, cake, pie, or brownies.
  • Note-you can make the hot fudge on the stovetop. Heat in a saucepan and stir until creamy and smooth. Again, add a little hot water if the sauce is too thick, but note it should be thick! Store hot fudge in the fridge for up to 2 weeks. Reheat in the microwave for 15 to 30 seconds and stir.

  1. So, my favorite podling, this is of course a more than worthy sauce! I would love to try it soon, my one question is how to store it and how best to reheat it…if there are any leftovers that is. I am worried that nuking it repeatedly could dry it out or make it grainy. Good work on the blog by the,way, always something yummy to dream about. Heartmathchef.

    1. Store it in the fridge and reheat in the microwave and stir. I added a note in the recipe. Enjoy!

  2. Honestly, wife and I decided that these days we are making recipes that are 5 ingredients or less.this is in.

  3. Oh, wow! This looks awesome. I have all ingredients on hand. While in my pantry I also discovered Trader Joe’s cookie butter. Hummm, I think I also have other possibilities. 

  4. Help! When my sauce came out of the microwave, it was smooth and yummy. Now that it’s cooled, I have a jar of fudge. It’s good – don’t me wrong. But I was hoping to spoon the sauce over ice cream. Any thoughts?

    1. It will harden up after it is cooled. Reheat. You can add a tablespoon of hot water too.

  5. The recipe sounds yummy. I wonder how long you would hot water bath you would do to can it. Sounds like a good Christmas present to make a head of time.

  6. I love this. So much. And your photos are amazing! When I try and take sauce photos they come out looking like a gross goopy mess LOL! I’m a sucker for plain vanilla ice cream, and this would be the perfect topping.

  7. 5 stars
    Can I work up your recipes to make them reduced sugar to sugar-free. I would appreciate permission and I will share with you.
