Easy Rum Balls (No‑Bake Chocolate Christmas Treat)
From Office Cookie Swap to Midnight Fridge Raids 🎄🥃
If there’s one plate that vanishes fastest at any December cookie exchange, it’s the glossy pile of easy rum balls—the grown‑up truffle that tastes like brownie batter met a splash of holiday spirit. These bite‑size sweets come together in minutes with three pantry staples: crumbled chocolate cake, sweetened condensed milk, and a good pour of dark rum. No oven, no candy thermometer, just mix, chill, roll, and shower in chocolate jimmies.
My grandmother called them “reindeer boosters” and kept a tin hidden in the butter compartment. Today, I make them for our staff cookie swap because they’re virtually foolproof, transport well, and feel luxuriously decadent next to basic sugar cookies. Plus, you can tweak the booze, add nuts, or dip in melted chocolate for an extra layer of indulgence.

Ingredient Breakdown & Substitutions
Ingredient | Base Amount | Purpose | Swap Ideas |
---|---|---|---|
Chocolate cake crumbs | 1 standard 9‑inch cake (about 4 cups crumbs) | Body & chocolate flavor | Brownie scraps, crushed chocolate wafer cookies. |
Sweetened condensed milk | ¼ cup | Binds & sweetens | 3 Tbsp corn syrup + 1 Tbsp cream. |
Dark rum | ½ cup | Signature warmth & moisture | Spiced rum, bourbon, Kahlúa, or rum extract (3 tsp + 2 Tbsp water) for zero‑proof. |

Optional boosters | Pinch salt, ½ tsp espresso powder, ½ cup finely chopped walnuts | Depth & texture | Orange zest & ground ginger for holiday spice. |

Troubleshooting Corner
Issue | Cause | Fix |
---|---|---|
Balls won’t hold shape | Crumbs too dry | Add 1 Tbsp condensed milk. |
Sticky mess | Too much liquid / warm hands | Chill dough longer; dust hands with cocoa. |
Sprinkles falling off | Surface too dry | Roll balls lightly in condensed milk before sprinkles. |
Tiny Kitchen Science – Why Rum Helps Bind
Alcohol lowers dough surface tension, letting condensed milk penetrate crumbs; ethanol evaporates slowly, allowing flavor to mellow while the balls firm up.
FAQ (Schema‑Ready)
Q – Can I make them kid‑friendly? Yes—replace rum with 3 Tbsp cocoa + 3 Tbsp milk + 1 tsp rum extract.
Q – Can I use gluten‑free cake? Absolutely; texture remains chewy.
Q – How strong is the alcohol? Each ball contains ≈ ½ tsp rum; flavor strong, intoxication minimal unless you eat the whole batch.
