Arrange packets in the slow cooker: Place the sealed foil packets in the slow cooker in a single layer if possible, or a slightly staggered second layer if needed. They can be nestled close together; just make sure they remain sealed so the sugar mixture doesn’t leak out.
Slow cook the monkey bread packets: Cover the slow cooker with its lid. Cook on HIGH for 2 to 2 1/2 hours, or on LOW for 3 1/2 to 4 hours, until the dough inside the packets is puffed, cooked through, and the sugar-butter mixture is bubbling. If you’re unsure, carefully open one packet with tongs and check that the dough pieces are no longer raw in the center.
Make the simple icing: About 10 minutes before the packets are done, whisk the powdered sugar with 2 tablespoons of milk or cream in a small bowl until smooth and pourable. Add more milk, a teaspoon at a time, until you reach a drizzle-able consistency. You want it thick enough to cling but thin enough to flow in ribbons.
Glaze the foil packets: When the packets are done, turn the slow cooker to WARM. Using tongs, gently nudge the packets so the tops are facing up and exposed. Drizzle the icing generously over the tops of the closed foil packets, letting it run and set over the warm foil. The heat from the packets will slightly melt and set the glaze.
Serve: Let the glazed packets sit for 5–10 minutes so the icing can firm up a bit. Set the slow cooker on a buffet or counter and invite everyone to grab a warm packet. To eat, carefully open the foil (watch for steam) and pull apart the sticky, sweet bites inside. Serve any extra icing on the side for those who like an extra drizzle.
Variations & Tips
For a cinnamon twist, whisk 1–2 teaspoons ground cinnamon into the brown sugar before mixing with the butter, mimicking classic monkey bread flavor without adding more ingredients. If you want a subtle citrus note, use orange-flavored refrigerated biscuits or add a teaspoon of finely grated orange zest into the brown sugar–butter mixture (this technically adds an ingredient, but it’s a small, high-impact tweak). You can also play with texture by using flaky-layer biscuits, which give more defined pull-apart layers inside each packet. For a slightly less sweet version, reduce the brown sugar to 3/4 cup and keep the butter amount the same; the packets will still be sticky but a bit more balanced. If you’re serving a crowd at a brunch, make smaller packets (12–14 instead of 8–10) for mini portions—just reduce the cook time slightly and start checking for doneness about 20–30 minutes earlier. To keep things tidy at a party, offer forks and small plates so guests can open the foil and eat right from the packet without any extra serving dishes.
