Ingredients for betty crocker chocolate peanut butter fudge

Simple pantry staples transform into restaurant-quality fudge with this classic Betty Crocker-inspired method.

The chocolate matters most here—Hershey’s Special Dark or Ghirardelli deliver that rich, velvety texture. Store-bought chocolate chips work fine, but if you’ve got time, melt a bar of semi-sweet chocolate for smoother results. Butter should be unsalted to control the final saltiness, and natural peanut butter (no added oils) gives the best flavor. For the sugar, superfine white sugar dissolves faster, but regular granulated works if you pulse it in a food processor first. Karo corn syrup is the gold standard for fudge—it prevents crystallization and keeps things glossy. If you can’t find it, light corn syrup is a fine substitute, though you might need to adjust the temperature slightly.

No creamy peanut butter? Crunchy works too—just blend it briefly to smooth out the texture. Short on chopped peanuts? Toasted pecans or walnuts add a different but delicious crunch. The recipe calls for powdered sugar to dust the top, but superfine sugar works in a pinch if you don’t have any. For a deeper chocolate flavor, swap 2 oz of the semi-sweet for dark chocolate chips. The vanilla extract should be pure, not imitation—it makes a noticeable difference. If you’re making this ahead, pre-measure everything the night before to save time. The chopped peanuts and peanut butter can be stored in the fridge for up to 1 week, but fresh is always better.

This fudge keeps beautifully—cool, dry conditions are key. Once set, it stays fresh for 2 weeks at room temperature if stored in an airtight container. For longer storage, wrap tightly in plastic wrap and refrigerate for up to 1 month. Freezing isn’t recommended as it can alter the texture. To serve, cut into 16 squares for perfect portions. The fudge thickens as it cools, so don’t overfill the pan. If it sets too firm, reheat gently in the microwave for 10-15 seconds to soften before serving. Leftovers? Portion into small containers for easy grab-and-go treats.

Step-by-step instructions for Betty Crocker chocolate peanut butter fudge recipe

Here's the method for creating rich, creamy fudge with a perfect crunchy peanut topping.

In a large, heavy-bottomed saucepan, combine the 12 oz semi-sweet chocolate chips and 1 cup unsalted butter. Place the saucepan over medium heat and stir gently until both ingredients melt completely. This should take about 5-7 minutes, and you'll know it's ready when the mixture is smooth and glossy.

I like to use a silicone spatula to scrape the bottom of the pan frequently—this prevents any chocolate from sticking and burning. Remove the pan from heat once fully melted, then stir in the 1 cup creamy peanut butter until completely smooth. The mixture should thicken slightly as it cools, so don't worry if it looks a bit heavier than when it was hot.

Return the saucepan to medium heat and add the 1.5 cups granulated white sugar, 0.5 cup light corn syrup, and 1 cup heavy cream. Stir constantly for 5-7 minutes until the sugar fully dissolves and the mixture reaches a gentle boil. You'll see small bubbles forming around the edges of the pan—this signals the sugar is incorporated.

Here's the thing—if the mixture boils too vigorously, it can burn. Keep the heat at a steady simmer rather than a rolling boil. Once boiling, cook for an additional 3-4 minutes until the mixture thickens to a soft-ball stage. To test, drop a small amount into cold water—it should form a firm ball that holds its shape when pressed between your fingers.

Remove the saucepan from heat and stir in the 2 tsp vanilla extract and 0.5 tsp salt. The vanilla adds depth, while the salt balances the sweetness. Next, fold in the 1.5 cups chopped peanuts using a rubber spatula, ensuring they're evenly distributed throughout the mixture. The peanuts will sink slightly but will create pockets of crunch in every bite.

Let the fudge mixture cool slightly for 10 minutes—it should be thick enough to hold its shape when dropped from a spoon but still warm to the touch. If it cools too much, you can gently reheat it over low heat for 1-2 minutes to restore its workability. This cooling step is crucial for preventing cracking when the fudge sets.

Lightly grease a 9x13-inch baking dish with butter or line it with parchment paper for easy removal. Pour the fudge mixture into the prepared dish and spread it evenly using a spatula. Tap the dish gently on the counter to eliminate any air bubbles that may have formed during pouring.

Sprinkle the 0.5 cup chopped peanut butter evenly over the top, pressing it lightly into the surface with the back of a spoon. This creates the signature crunchy topping that contrasts beautifully with the creamy fudge beneath. Let the fudge cool completely at room temperature for 2-3 hours, or until firm to the touch. Avoid refrigerating during this time—it needs to set at room temperature for the best texture.

Once the fudge is completely set, dust the top evenly with the 1 cup powdered sugar using a fine-mesh sieve. This adds a delicate sweetness and a professional finish. For an optional deeper flavor, press the 2 oz dark chocolate chips into the top before dusting with powdered sugar.

Use a sharp knife to cut the fudge into 16 equal squares. To ensure clean cuts, dip the knife in hot water between each slice. Let the fudge rest for another 10 minutes before serving—this allows the powdered sugar to adhere fully and the cuts to set. Store any leftovers in an airtight container at room temperature for up to 5 days, though I doubt it will last that long!

Common mistakes when making your betty crocker chocolate peanut butter fudge

Boiling Too Fast

If your sugar mixture boils too vigorously, it can burn before reaching the proper consistency. I’ve seen this happen when heat is too high or the pan isn’t heavy enough. To prevent this, use medium-low heat and stir constantly with a silicone spatula—this helps regulate temperature.

A heavy-bottomed saucepan (like All-Clad) distributes heat evenly, reducing hot spots that cause burning. If you notice the mixture darkening, remove it from heat immediately and let it cool slightly before continuing. 🔥

Undercooked Sugar Mixture

Fudge that’s undercooked will be too soft and sticky, failing to set properly. The key is reaching the soft-ball stage—when a drop forms a firm ball in cold water. I test this by dipping a spoon into the mixture and dropping it into ice water.

If it doesn’t hold shape, cook for 1-2 more minutes until it does. Rushing this step often leads to grainy or crumbly fudge. Patience here makes all the difference in texture. ⏰

Overmixing After Peanuts

Once you fold in the chopped peanuts, resist the urge to overmix. Stir just until they’re evenly distributed—overworking the mixture incorporates too much air, which can cause cracks as it sets. I use a spatula to gently fold in peanuts in one direction, then stop.

If the fudge looks too thick, reheat it gently for 30 seconds to restore smoothness before pouring. Overmixing is a common mistake that ruins the creamy consistency. 🥜

Skipping the Cooling Step

Letting the fudge cool for 10 minutes before pouring is critical—skipping this causes it to set too quickly, leading to cracks or a grainy texture. I’ve learned this the hard way! If the mixture is too hot, it’ll melt any peanut butter topping or cause the powdered sugar to clump.

To test readiness, drop a spoonful onto a plate—it should hold its shape but still be pourable. This step ensures a smooth, glossy finish. ⚡

Greasing the Pan Improperly

A poorly greased pan causes fudge to stick or tear when cutting. Lightly butter the pan and line it with parchment paper for foolproof release. I use a pastry brush to apply butter evenly, then press parchment into corners.

If you skip this, the fudge may cling, especially in humid conditions. For extra insurance, dust the parchment with powdered sugar before pouring. This ensures clean slices every time. ✨

Cutting Too Soon

Fudge needs 2-3 hours to fully set before cutting—rushing this results in messy, crumbly pieces. I wait until it’s firm to the touch and dusted with powdered sugar. To cut cleanly, use a sharp chef’s knife (like Wüsthof) and dip it in hot water between slices.

If the fudge feels too soft, chill it in the fridge for 10 minutes before cutting. Patience here guarantees perfect squares. 💡
