What You Need for Microwave Peanut Butter Fudge

Gathering the right ingredients is essential for creating delicious Microwave Peanut Butter Fudge. This recipe highlights the natural sweetness of peanut butter while enhancing it with complementary flavors. Each ingredient plays a crucial role in achieving the perfect fudge texture and taste. Let’s dive into the key players:
- 10 oz. peanut butter chips: These chips are the star of the show, providing that creamy peanut butter flavor that we all love. They melt beautifully and form the base of the fudge.
- 1 can sweetened condensed milk (14 oz.): This ingredient adds the necessary sweetness and creaminess, making the fudge rich and smooth.
- ⅓ cup creamy peanut butter: A bit of extra peanut butter enhances the flavor and richness of the fudge, ensuring every bite is packed with that delightful taste.
- 1½ tsp vanilla extract: A touch of vanilla adds depth to the flavor profile, balancing the sweetness of the fudge.
- ⅔ cup marshmallow creme: This fluffy ingredient contributes to the fudgy texture and adds a subtle sweetness.
- 1 cup mini marshmallows (optional): If you want to add a fun texture and extra sweetness, fold in some mini marshmallows.
How to Assemble Microwave Peanut Butter Fudge

Making Microwave Peanut Butter Fudge is a straightforward process that anyone can master. It’s all about combining the ingredients and giving them a little heat!
- Start by gathering all your ingredients. It’s always easier to have everything on hand before you begin. Measure out 10 oz. peanut butter chips and place them into a microwave-safe bowl along with 1 can of sweetened condensed milk.
- Microwave the mixture on high for 20-second increments. After each increment, stir the mixture to help it melt evenly. Expect this step to take about 1 to 1½ minutes. Keep an eye on it—once everything is melted and smooth, you’re ready for the next step!
- Once the mixture is melted and creamy, add in ⅓ cup creamy peanut butter and 1½ tsp vanilla extract. Stir well to combine everything; you should have a rich, thick mixture.
- Now, gently fold in ⅔ cup marshmallow creme. Be careful not to over-stir; you want to keep that light, fluffy texture. If you are using 1 cup mini marshmallows, fold them in at this point.
- Prepare an 8×8 inch pan by lining it with parchment paper or greasing it well. This will help you remove the fudge easily once it’s set. Pour the fudge mixture into the pan and spread it into an even layer.
- Refrigerate the fudge for a few hours, or until it’s completely set. This step is crucial for the fudge to hold its shape.
- Once it’s set, take the fudge out of the refrigerator. Lift it out of the pan using the parchment paper and place it on a cutting board.
- Using a sharp knife (or dental floss for perfectly smooth cuts), cut the fudge into squares measuring about 1 to 1½ inches. This size is perfect for popping in your mouth!
- Store the fudge in an airtight container. If you keep it in the refrigerator, it can last for about two weeks, making it a great treat to have on hand.
Things Worth Knowing
- Don’t overheat the fudge. Overheating can cause it to become dry and clumpy. You want a smooth, creamy texture.
- Use a microwave-safe bowl for melting. Ensure that the bowl can withstand high temperatures without warping.
- Triple-check your ingredients. Make sure you’re using sweetened condensed milk and not evaporated milk, as the two are not interchangeable.
- For clean cutting, run your knife under hot water and dry it before cutting the fudge. This will help create neat, smooth edges.
Customization Ideas

Customizing your Microwave Peanut Butter Fudge is not only fun but allows you to tailor it to your preferences. Here are some ideas to inspire your next batch:
- Add Nuts: Incorporate chopped nuts like peanuts or almonds to add crunch and an extra layer of flavor.
- Mix in Chocolate: Swap out some peanut butter chips for chocolate chips or swirl melted chocolate on top for a decadent touch.
- Use Different Extracts: Experiment with almond or hazelnut extract to switch up the flavor profile.
- Drizzle Caramel: Add a drizzle of caramel sauce on top before chilling for a sweet finish.
- Experiment with Flavors: Consider added spices like cinnamon or sea salt for a unique twist on the classic recipe.
- Try Different Shapes: Instead of cutting into squares, mold the fudge into fun shapes using cookie cutters.
