My aunt brings this to every party. Only 3 ingredients for a rich and boozy chocolate treat

My aunt Doris has been bringing this fudge to every church social, holiday open house, and backyard card party since the late ’80s. Folks hover around the dessert table just waiting for her to lift the foil off those pans. It’s rich, deeply chocolatey, and has that soft Baileys warmth that sneaks up on you in the nicest way. The best part is, it only takes three ingredients and a slow cooker does most of the work, so it fits right into the kind of practical, no-fuss cooking I grew up with on the farm. This is the kind of recipe you tuck into your recipe box and pass down, because it never goes out of style and it always, always gets invited back.

Cut the fudge into small, neat squares and serve it cold or at cool room temperature on a simple platter or straight from those foil-lined trays. It pairs beautifully with hot coffee, a cup of black tea, or a cold glass of milk. For a party, I like to arrange the pieces with some salty snacks—pretzels or roasted nuts—so folks can go back and forth between sweet and salty. If you’re really leaning into the Baileys theme, a little after-dinner nip of Irish cream on the side makes this feel extra special without any extra work.

Servings: 36–48 small squares, depending on how you cut it

3 cups (about 18 oz / 510 g) semi-sweet chocolate chips

Line 3 to 4 small foil trays or 1 large 9x13-inch pan with aluminum foil, letting some foil hang over the sides to make lifting easier later. Lightly grease the foil with a bit of butter or nonstick spray so the fudge releases cleanly and keeps that smooth, glossy finish.

Set your slow cooker to LOW. Pour in the sweetened condensed milk, then add the chocolate chips and Baileys Irish Cream. Do not stir yet; just let everything settle in an even layer so it melts gently.

Cover the slow cooker with the lid and let the mixture warm on LOW for about 45 minutes. Avoid lifting the lid during this time so the heat stays steady and the chocolate melts evenly.

After 45 minutes, remove the lid and gently stir the mixture with a heatproof spatula. Scrape along the bottom and sides so no chocolate sticks and scorches. The mixture will start to look thick, shiny, and very smooth.

Continue cooking on LOW for another 15–30 minutes, stirring every 10 minutes, until the fudge mixture is completely smooth, glossy, and quite thick. It should fall off the spatula in a heavy ribbon. Be patient and keep the heat low; slow and gentle gives you a dense, fine texture and a nice sheen.

Turn off the slow cooker and let the mixture sit for 5 minutes, then give it one last good stir to knock out any stubborn streaks. This final stir helps you get that uniform, velvety look when you slice the fudge.

Carefully pour or scrape the hot fudge mixture into your prepared foil-lined trays or pan. Spread it out with the spatula, smoothing the top as much as you can. For those clean, sharp cuts later, try to get the surface as level as possible now.

Let the fudge cool at room temperature until it is no longer warm to the touch, about 1–2 hours. Then cover the trays lightly with foil and refrigerate for at least 3–4 hours, or overnight, until the fudge is very firm all the way through.

Once chilled and set, lift the fudge out of the trays using the overhanging foil. Place 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 to keep the edges neat and the surface glossy.

Arrange the squares back in the foil trays or on a serving plate. Store the fudge covered in the refrigerator for up to 2 weeks. For the best texture and flavor, let the pieces sit out for about 10 minutes before serving so the chocolate softens just slightly but still holds those nice, dense, clean cuts.

For a stronger Baileys flavor, you can increase the Baileys to 1 cup and reduce the sweetened condensed milk slightly (use about 1 3/4 cans total), but keep in mind the fudge will be a touch softer and richer. If you prefer a milder, more kid-friendly version, use only 1/2 cup Baileys and add an extra 1/2 cup chocolate chips to keep the texture firm. You can also play with the chocolate: swap half the semi-sweet chips for dark chocolate chips for a deeper cocoa taste, or use all milk chocolate chips for a sweeter, creamier fudge. Just keep the total amount of chocolate the same so it sets properly. To dress it up without adding ingredients into the base, you can press a few chocolate chips or a light sprinkle of flaky salt on top right after spreading the fudge in the pan—this doesn’t change the simple 3-ingredient base but gives a pretty finish. If your slow cooker runs hot, prop the lid open slightly with a wooden spoon during the last part of cooking and stir more often to prevent scorching. For the cleanest cuts, chill the fudge overnight, use a long, sharp knife, and run the blade under hot water, wiping it dry between slices. This recipe also travels well: keep the fudge right in those foil trays, cover tightly, and tuck into a cooler for potlucks, just like my aunt has done for years.
