Ingredients for Peanut Butter Fudge Recipe with Peanut Butter Chips
Rich, creamy indulgence with nutty goodness in every bite. Simple ingredients, extraordinary results.
| Ingredient | Amount | Notes |
|---|---|---|
| Granulated Sugar 🍚 | 2 cups | For sweetness and texture |
| Packed Light Brown Sugar 🍚 | 1 ½ cups | Adds moisture and caramel notes |
| Creamy Peanut Butter 🥜 | 1 cup | High-quality, no added sugar |
| Unsalted Butter 🧈 | ¾ cup | Cut into cubes for even melting |
| Evaporated Milk 🥛 | ⅔ cup | Canned, full-fat for creaminess |
| Peanut Butter Chips 🍫 | 1 ½ cups | Divided for melting and mixing |
| Vanilla Extract 🌿 | 2 tsp | Pure, not imitation |
| Marshmallow Fluff ⚪ | 1 jar | 7 oz jar for fluffiness |
| Sea Salt 🧂 | ½ tsp | Fine grain for even distribution |
| Heavy Cream 🥛 | ¼ cup | Optional for extra richness |
The peanut butter is the star here. Jif Natural or Skippy Creamy both work great—avoid the reduced-fat versions, as they can separate or dry out the fudge. Hershey’s peanut butter chips are the easiest to find at most grocery stores, but Reese’s brand adds a slightly saltier kick. For the evaporated milk, any brand will do, but Carnation is the most consistent for texture.
No peanut butter chips? Chopped salted peanuts add a similar crunch (use about 1 cup). Swap the marshmallow fluff for 10 oz mini marshmallows if that’s what you’ve got. For a dairy-free version, use coconut oil instead of butter and coconut milk instead of evaporated milk. The vanilla extract can be imitation in a pinch, but pure tastes noticeably better.
Fudge keeps beautifully at room temperature for up to 2 weeks in an airtight container. For longer storage, freeze for 3 months—just thaw overnight in the fridge before serving. The texture actually improves after a day or two as the flavors meld together (worth the wait).

Step-by-Step Instructions for Peanut Butter Fudge With Peanut Butter Chips
This method ensures smooth, creamy fudge with that perfect melt-in-your-mouth texture every time.
Step 1: Melt and Combine the Sugar Base
In a heavy-bottomed saucepan, combine the 2 cups Granulated Sugar, 1.5 cups Packed Light Brown Sugar, 0.75 cup Unsalted Butter, and 0.66 cup Evaporated Milk. I always use a heavy pan to prevent scorching—this mixture gets hot and sticky.
Cook over medium heat, stirring constantly with a wooden spoon, until the mixture reaches a full rolling boil. You’ll see large, vigorous bubbles that can’t be stirred down. This boiling process dissolves the sugars and creates the foundation for your fudge’s smooth texture.
Continue boiling for exactly 4 minutes without stirring. This is crucial for reaching the soft-ball stage (about 234-238°F on a candy thermometer). The mixture will look slightly thickened and syrupy when it’s ready.
Step 2: Incorporate the Peanut Butter Mixture
Immediately remove the pan from heat and stir in the 1 cup Creamy Peanut Butter, 1 jar Marshmallow Fluff, 2 tsp Vanilla Extract, and 0.5 tsp Sea Salt. The peanut butter should melt completely into the hot sugar mixture, creating a glossy, caramel-colored base.
I add the marshmallow fluff off heat to prevent it from melting too quickly and losing its fluffy texture. The vanilla and salt balance the sweetness and enhance the peanut flavor. Stir vigorously for 1-2 minutes until everything is completely smooth and well combined.
If using, now’s the time to stir in the 0.25 cup Heavy Cream for an even richer, creamier texture. This step transforms the mixture from a simple sugar syrup to a luxurious fudge base with depth of flavor.
Step 3: Fold in Most of the Peanut Butter Chips
Reserve ½ cup of the 1.5 cups Peanut Butter Chips for topping, then quickly fold the remaining 1 cup into the fudge mixture. The chips will begin to soften and distribute evenly, creating pockets of peanut butter goodness throughout.
Work fast here—the fudge begins to set as it cools. I use a silicone spatula to scrape the bottom and sides of the pan, ensuring all those delicious peanut butter chips are fully incorporated. The mixture should look thick, glossy, and studded with melting chips.
Step 4: Set and Finish the Fudge
Pour the fudge into a greased 9×13-inch baking pan and spread it evenly with your spatula. The surface should be smooth with a slight sheen. Immediately sprinkle the reserved ½ cup Peanut Butter Chips evenly over the top, pressing them in lightly so they adhere as the fudge sets.
Let the fudge cool to room temperature, then refrigerate for at least 2 hours until completely firm. I’ve found that cutting it too soon results in a gooey mess rather than clean squares. Once set, the fudge should be firm to the touch but still yield slightly when pressed.
Cut into 1-inch squares and serve at room temperature for the best texture. The reserved chips on top provide a pretty finish and an extra burst of peanut butter flavor in every bite.
Pro Tips For Making Peanut Butter Fudge Recipe With Peanut Butter Chips
- Boil to 234°F: Use a candy thermometer and pull the sugar mixture off the heat exactly at 234°F—any higher and your fudge will turn grainy. I learned this the hard way after ruining two batches by guessing.
- Melt the Butter First: Soften the unsalted butter and melt it slightly before mixing with peanut butter—it blends smoother and prevents those little butter lumps in your fudge.
- Skip Low-Fat Peanut Butter: Full-fat creamy peanut butter is non-negotiable here; the reduced-fat version separates and leaves your fudge oily. Sounds weird, but it works: stick to the real stuff.
- Fold Chips Last: Wait until the fudge is off the heat and just starting to thicken before folding in the peanut butter chips—adding them too early melts them into the mix, losing that nice chip texture.
Make-Ahead Tips for peanut butter fudge recipe with peanut butter chips
Prep Ahead Strategy
I always measure all dry ingredients the night before and store them in airtight containers. This includes the 2 cups Granulated Sugar and 1.5 cups Packed Light Brown Sugar. It saves precious minutes on cooking day.
Chip Prep Tip
Divide your 1.5 cups Peanut Butter Chips into two portions ahead of time—1 cup for mixing and ½ cup for topping. Keep them in separate bowls covered with plastic wrap to prevent melting. 💡
Pan Preparation
Line your 9×13-inch baking pan with parchment paper the day before. This ensures easy removal and clean cuts. I use Reynolds parchment for its non-stick reliability. Lightly greasing the paper helps the fudge release even easier.
Pre-Measure Liquids
Have your 0.75 cup Unsalted Butter, 0.66 cup Evaporated Milk, and 0.25 cup Heavy Cream measured and ready. Cold ingredients can cause the sugar mixture to seize, so let them sit at room temperature for 30 minutes before starting.
Flavor Development
Mix the 1 cup Creamy Peanut Butter, 1 jar Marshmallow Fluff, 2 tsp Vanilla Extract, and 0.5 tsp Sea Salt in a separate bowl. This ensures they incorporate smoothly into the hot sugar mixture without clumping.
Final Assembly Setup
Have your spatulas, candy thermometer, and cooling rack ready to go. I keep a damp towel nearby for quick cleanup of sticky utensils. The fudge sets fast, so having everything prepared prevents frantic searching mid-process. 🔥

Frequently Asked Questions
Can I use crunchy peanut butter instead of creamy?
Yes, but it will change the texture slightly. Crunchy adds extra nut pieces, while creamy gives that signature smooth melt-in-your-mouth feel. For best results, stick with creamy.
Why does my fudge sometimes turn grainy?
Graininess usually means the sugar crystallized. Prevent this by stirring constantly during boiling and avoiding the pan’s sides where sugar can stick. Use a candy thermometer for accuracy.
How long does it need to set before cutting?
Refrigerate for at least 2 hours until completely firm. Cutting too soon results in messy squares. For cleanest cuts, let it sit overnight.
Can I substitute something for marshmallow fluff?
Yes, use 10 oz mini marshmallows melted with the peanut butter. They provide the same fluffy texture and sweetness to balance the richness.
