Ingredients
-
3 cups Rice Krispies cereal
-
1 cup creamy peanut butter
-
1 can (14 oz) sweetened condensed milk
-
2 cups white chocolate chips
-
1 teaspoon vanilla extract
-
¼ teaspoon salt
-
Optional: ½ cup chopped peanuts for extra crunch
Directions
Prepare the Pan
Start by preparing your baking pan. Take an 8×8-inch square pan and line it with parchment paper. Make sure to leave a generous overhang on two opposite sides; this will make it much easier to lift the fudge out later without breaking it. Lightly grease the parchment paper with a small amount of butter or non-stick cooking spray to prevent the fudge from sticking. A well-prepared pan is key to achieving clean, even squares and will save you frustration when it’s time to remove the fudge. Take your time here—lining and greasing the pan thoroughly ensures a smooth, easy process later.
Melt the Peanut Butter Mixture
Next, move to a medium-sized saucepan and set it over low heat. Add 1 cup of creamy peanut butter along with a full 14-ounce can of sweetened condensed milk. It’s important to use low heat here to avoid scorching or separating the mixture. Stir continuously with a heat-resistant spatula or wooden spoon. The goal is to achieve a perfectly smooth and fully blended mixture, free of lumps. As you stir, you’ll notice the peanut butter gradually loosening and combining seamlessly with the condensed milk, creating a glossy, thick mixture. Once fully blended, remove the saucepan from the heat and add 1 teaspoon of vanilla extract and ¼ teaspoon of salt. Stir well to ensure the flavors are evenly distributed. This mixture forms the rich, creamy base of your fudge, so patience here pays off in flavor and texture.
Add White Chocolate Chips
While the peanut butter mixture is still warm, it’s time to incorporate the white chocolate chips. Add 2 cups of white chocolate chips directly into the saucepan. Using a spatula, fold them in gently. The residual heat from the peanut butter mixture will melt the chips, creating a luxuriously smooth, creamy consistency. Take your time to ensure every chip is fully melted and blended. This step is crucial because the white chocolate not only adds sweetness but also gives the fudge its characteristic creamy texture, which contrasts beautifully with the crispiness of the cereal. If some chips take a little longer to melt, you can place the pan back over low heat for a few seconds, stirring continuously until fully incorporated.
Mix in Rice Krispies
Now comes the fun part: adding the Rice Krispies cereal. Gradually fold in 3 cups of Rice Krispies, making sure every piece is coated with the warm, creamy peanut butter and white chocolate mixture. Be gentle—stirring too vigorously can crush the cereal and compromise that satisfying crunch that makes this fudge so special. Use a folding motion to preserve the light, airy texture of the cereal while ensuring even coating. At this stage, the mixture should be thick but pliable, with each Rice Krispie enveloped in creamy sweetness.
Add Optional Peanuts
For those who love an extra layer of texture, fold in ½ cup of chopped peanuts. This step is optional, but the added crunch complements the softness of the fudge beautifully and enhances the peanut flavor. Be sure to distribute the peanuts evenly throughout the mixture so that every bite contains a bit of crunch and added nutty goodness. This optional step allows you to customize the fudge to your preference, making it uniquely yours.
Transfer to Pan
Once all ingredients are fully incorporated, transfer the mixture into the prepared baking pan. Use a spatula or the back of a spoon to press the mixture down evenly. Press firmly but gently to compact the fudge without crushing the cereal. Smooth the top as much as possible to ensure even squares later. A flat, well-pressed top also helps the fudge set more uniformly in the fridge. Don’t rush this step—taking the time to distribute the mixture evenly ensures that the fudge looks as good as it tastes.
Chill to Set
Place the pan in the refrigerator and allow the fudge to chill for at least 2 hours, or until it becomes firm to the touch. If you’re short on time, you can place the pan in the freezer for 30–40 minutes, which speeds up the setting process. Chilling is crucial because it allows the fudge to solidify, making it easier to cut into clean squares without crumbling. Resist the urge to slice it too early; the fudge will be soft and sticky if not fully set.
Slice and Serve
After the fudge has set, carefully lift it from the pan using the parchment overhang. Place it on a cutting board and slice into squares or rectangles using a sharp knife. For neat cuts, you can lightly grease the knife or warm it under hot water and dry it before slicing. Arrange the fudge on a serving platter and enjoy immediately, or store in an airtight container in the refrigerator for up to a week. These squares are perfect for sharing with friends and family, gifting, or simply indulging in a delicious treat anytime.
Tips for Perfect Peanut Butter Rice Krispies Fudge

Use creamy peanut butter: This ensures a smooth, luscious fudge texture. Chunky peanut butter can make mixing difficult and uneven.
-
Don’t overheat the mixture: Keep the heat low while melting to prevent scorching the peanut butter or condensed milk.
-
Press firmly into the pan: This helps the fudge hold together and makes slicing easier.
-
Customize your crunch: Experiment by adding mini chocolate chips, butterscotch chips, or even a swirl of Nutella for added flavor.
Why This Recipe Works
The magic of this fudge lies in its combination of textures and flavors. The creamy peanut butter and sweetened condensed milk create a smooth, rich base that melts in your mouth.
