My coworker brought this to our potluck and it was gone before anyone got seconds. Melt in your mouth good

This slow cooker 3-ingredient peanut butter fudge is the kind of treat that disappears at potlucks before anyone can go back for seconds. A coworker of mine brought a pan of it once, and people were literally scraping the parchment for crumbs. It’s melt-in-your-mouth creamy, sweet but not over-the-top, and has that old-fashioned fudge texture without any candy thermometers or fancy tricks. Everything melts together low and slow in the crockpot while you go about your day, and by the time it’s set you’ve got a pan full of soft, glossy, light-tan squares that look like you fussed way more than you actually did.

Cut the fudge into small, bite-sized squares and serve it on a simple platter or in a shallow bowl lined with parchment so pieces don’t stick. It pairs nicely with salty snacks like pretzels or mixed nuts to balance the sweetness, and a pot of coffee, hot cocoa, or cold milk makes it feel like a cozy little dessert spread. For gatherings, tuck the fudge between bowls of fresh fruit or a simple cheese board so everyone can build a small plate with a mix of sweet and salty. At home, I like to keep a few pieces in the fridge and pull them out after dinner for an easy, no-fuss treat.

Servings: 24

2 cups creamy peanut butter (not natural, well-stirred)

Line an 8x8-inch or 9x9-inch baking pan with parchment paper, letting it overhang the sides so you can lift the fudge out later. Lightly smooth the parchment into the corners so it lies as flat as possible for even, glossy tops.

Lightly spray the inside of your slow cooker with nonstick cooking spray or wipe it with a thin layer of neutral oil to help with cleanup and prevent sticking.

Add the white chocolate chips and the sweetened condensed milk to the slow cooker. Spoon the peanut butter on top. Do not stir yet; letting the ingredients warm gently before stirring helps everything melt more smoothly.

Cover the slow cooker with the lid and set it to LOW. Cook for 45 minutes to 1 hour, until the white chocolate chips look soft and beginning to lose their shape. Try not to remove the lid more than once or twice so you keep the heat in.

Uncover and stir the mixture slowly but thoroughly with a heat-safe spatula, scraping along the bottom and sides of the crock. Keep stirring until the mixture is completely smooth, thick, and glossy with no visible streaks of peanut butter or white chocolate. If some chips remain, cover and cook on LOW for another 10–15 minutes, then stir again.

Once the mixture is smooth and uniform, immediately pour or scrape the hot fudge base into the prepared parchment-lined pan. Use your spatula to spread it into an even layer, gently smoothing the top so it looks glossy and level. Tap the pan lightly on the counter a few times to help any air bubbles rise and to settle the fudge.

Let the pan sit at room temperature on a cool, level surface for about 30–45 minutes to take the initial heat off. Then transfer it to the refrigerator and chill for at least 2–3 hours, or until the fudge is very firm to the touch and cuts cleanly. For the best texture, avoid covering the pan tightly while it’s still warm to prevent condensation from forming on top.

Once fully set, use the parchment overhang to lift the entire block of fudge out of the pan and place it on a cutting board. Use a long, sharp knife to cut into small, even squares—wiping the knife with a warm, damp cloth between cuts helps keep the edges neat and the tops smooth and shiny.

Serve the fudge squares at cool room temperature so they stay soft and melt-in-your-mouth. Store any leftovers in an airtight container, with parchment between layers to prevent sticking, in the refrigerator for up to 1 week or in the freezer for up to 2 months.

For a slightly less sweet version, you can swap half of the white chocolate chips for peanut butter chips, which deepens the peanut flavor while keeping the fudge creamy. If your family likes a little crunch, stir in 1/2 to 3/4 cup of chopped roasted peanuts or crushed pretzels right after the mixture turns smooth and glossy, then spread it into the pan. For a fun twist for kids, sprinkle mini chocolate chips, peanut butter chips, or colorful sprinkles over the top as soon as you spread the fudge; gently press them in so they stick without losing that smooth, shiny finish. If you have peanut allergies in the house, you can make this with creamy almond butter or sunflower seed butter—just choose a thicker, no-stir style so the fudge sets firmly. For a darker, richer flavor, replace 1 cup of the white chocolate chips with semi-sweet chocolate chips; the fudge will be a bit firmer and not as light tan, but still very creamy. Food safety tips: Always use sweetened condensed milk, not evaporated milk, so the fudge sets safely and properly. Keep your slow cooker on LOW; cooking on HIGH can scorch the chocolate and cause it to seize or burn on the bottom. Stir carefully with a heat-safe spatula and avoid getting any water into the mixture, as water can cause the chocolate to seize and turn grainy. Let the fudge cool on the counter before covering tightly or stacking to prevent condensation, which can lead to a sticky surface and shorten shelf life. When serving at potlucks, keep the fudge out of direct sun and bring only what can be eaten within a couple of hours, refilling from a chilled container as needed so it stays firm and safe.
