Brown Sugar Rum Muffins are tender, lightly spiced muffins with dark rum–soaked raisins and a simple rum brown sugar glaze on top. They taste like a cozy bakery muffin, but with a warmer, deeper sweetness from brown sugar and rum.
I like this version because the crumb stays soft and moist, and the raisins don’t end up dry or chewy in a bad way. The glaze is quick and a little glossy, and it gives you that buttery brown sugar finish that makes these feel special.
For me, these are best for weekend breakfasts, holiday mornings, or an easy brunch spread. They’re also great with a cup of coffee when you want something a little more interesting than a plain muffin.
Why You’ll Love This Recipe
Warm and Spiced: Cinnamon and nutmeg give these that familiar cozy flavor that works really well with brown sugar.
Raisins That Actually Taste Good: Soaking the raisins first makes them plump and flavorful instead of dry little bits.
Quick Glaze: The rum brown sugar glaze comes together fast and sets up nicely on top.
Tender Crumb: Buttermilk and melted butter keep the muffins soft, as long as you don’t overmix.
Easy to Tweak: You can swap the fruit, add nuts, or make it alcohol-free without changing the whole recipe.
Ingredients You’ll Need
Muffins
- Raisins: Regular raisins are great, but golden raisins work too if you like a milder raisin flavor. The soak makes them much softer.
- Dark rum: I like dark rum here because it tastes a little richer and more “brown sugar-ish.” If you don’t want alcohol, apple juice or milk works fine, and you can add a little rum extract if you want.
- All-purpose flour: I use regular flour here. Spoon and level if you tend to pack flour into the cup.
- Baking powder: This gives the muffins most of their lift.
- Baking soda: Don’t skip it since the batter has buttermilk, and the soda helps the muffins rise and brown nicely.
- Fine salt: Just enough to keep the sweetness from tasting flat.
- Ground cinnamon: This is the main spice, so use one you actually like the taste of.
- Ground nutmeg: A little goes a long way. Fresh grated is nice, but the regular jar kind is totally fine.
- Light brown sugar: This is the main flavor of the muffin. Dark brown sugar works too if you want a stronger molasses taste.
- Eggs: Use large eggs. They help the muffins hold together and stay tender.
- Buttermilk: Buttermilk gives a softer texture and a slight tang that works really well with brown sugar.
- Unsalted butter: Melted butter keeps things simple. Let it cool a bit so it doesn’t scramble the eggs.
- Vanilla extract: Vanilla rounds out the rum and spice flavors.
- Nonstick spray or paper liners: Liners are easiest, but greasing the pan works fine too.
Rum Brown Sugar Glaze
- Unsalted butter: This makes the glaze taste rich instead of just sweet.
- Brown sugar: It gives the glaze that caramel-like flavor and a little depth.
- Dark rum: Just a little adds warmth. You can use milk or apple juice instead if you’re skipping alcohol.
- Powdered sugar: This thickens the glaze and helps it set up on the muffins.
- Milk: Add it slowly so you don’t end up with a thin glaze. You can always thin it, but thickening it back up is harder.
- Salt: A pinch makes the glaze taste less one-note.
Recipe Instructions
- Preheat the oven: Heat the oven to 375°F, then line a 12-cup muffin pan with paper liners or spray it well with nonstick spray.
- Soak the raisins: Toss the raisins with the rum and let them stand for 10 minutes. Drain the raisins and reserve 1 tablespoon of the soaking liquid.
- Mix the dry ingredients: Whisk the flour, baking powder, baking soda, salt, cinnamon, and nutmeg in a medium bowl.
- Mix the wet ingredients: In a large bowl, whisk the brown sugar, eggs, buttermilk, melted cooled butter, vanilla, and the reserved soaking liquid until smooth.
- Combine the batter: Fold the wet ingredients into the dry ingredients just until combined, then fold in the drained raisins.
- Fill the muffin pan: Divide the batter evenly between the muffin cups, filling each about three-quarters full.
- Bake: Bake for 16 to 20 minutes, until the tops spring back lightly and a toothpick comes out clean.
- Cool: Let the muffins cool in the pan for 5 minutes, then move them to a rack.
- Make the glaze: Warm the butter, brown sugar, and rum just until the sugar dissolves, then let it cool for 2 minutes.
- Finish the glaze: Whisk in the powdered sugar, a pinch of salt, and enough milk (1 to 2 tablespoons) to make a thick, pourable glaze.
- Glaze the muffins: Drizzle the glaze over warm muffins and let it set for about 10 minutes before serving.
Some of my tips!
This is the part that really makes a difference. If you only read one section, make it this one because this is where I share the little trick that helps the recipe turn out so well.
Recipe Tips & Tricks
Don’t overmix the batter. Stir just until you stop seeing dry flour. Overmixing makes muffins tough fast.
Drain the raisins well. You want them soaked and plump, but not dripping wet. Too much extra liquid can make the batter loose.
Keep an eye on the bake time. Start checking around 16 minutes, especially if your oven runs hot. Pull them when a toothpick comes out clean and the tops spring back.
Let the glaze cool for a minute. If you whisk powdered sugar into a boiling hot pan, it can get a little weird and grainy. Two minutes of cooling is usually enough.
Add nuts if you like crunch. Chopped pecans are really good here, and they don’t overpower the rum or spices.
Make some touches!
There are plenty of easy ways to serve this depending on the occasion. Keep it simple, or add a few small touches to make it feel a little more special.
Serving Suggestions
- Coffee or espresso: These are really good with coffee, especially something not too sweet like a latte or black coffee.
- Fresh fruit: Serve with berries, sliced oranges, or a simple fruit salad. It’s nice with the warm spice flavor.
- Yogurt: Plain or vanilla Greek yogurt on the side makes this feel more like a real breakfast. I’ll sometimes add a little cinnamon to the yogurt.
- Brunch spread: Add scrambled eggs and a salty side like bacon or sausage. The sweet muffins work well with something savory.
Save it for later
This section covers how to store leftovers and what parts of the recipe you can prepare ahead of time.
Storage and Make Ahead
Store them airtight at room temperature for 2 days. I keep them covered so the glaze doesn’t dry out too much.
If you want them longer, freeze the muffins for up to 2 months. I like freezing them in a single layer first, then moving them to a freezer bag.
Thaw at room temperature or overnight in the fridge. If you want them warm, a quick 10 to 15 seconds in the microwave brings them right back.
A few quick answers

Recipe FAQs
Can I make these alcohol-free?
Yes. Use apple juice or milk in place of the rum for soaking the raisins and in the glaze. If you still want a little rum flavor, add about 1/2 teaspoon rum extract to the batter.
Can I swap the raisins for something else?
You can. Chopped dates are great if you want something softer and sweeter, and dried cranberries work if you like a little tartness.
How do I know when the muffins are done?
The tops should spring back when you press lightly, and a toothpick should come out clean. If you hit a raisin with the toothpick, test again in another spot.
Can I add nuts?
Yes, and I recommend it if you like texture. About 1/2 cup chopped pecans mixed into the batter is enough to get some crunch without taking over.
Why did my muffins turn out dense?
The most common reason is overmixing once the flour is added. Also check that your baking powder and baking soda are fresh, since old leaveners can give you a heavy muffin.
