Eggnog Cupcakes Recipe with Spiced Rum Glaze

If you love eggnog at the holidays, these eggnog cupcakes are sure to delight. They capture the best parts of classic eggnog—creamy texture, warm nutmeg, and sweet vanilla—and transform them into tender cupcakes finished with a silky eggnog buttercream.

Perfect for Christmas parties, holiday gatherings, or simply when you want to make ordinary cupcakes feel festive, these treats have eggnog flavor in both the cake and the frosting so each bite tastes like the season.

I bake these whenever family is visiting during December; the scent of nutmeg while they bake fills the house with holiday cheer. I often garnish them with a little extra grated nutmeg, red and green sprinkles, or tiny gingerbread decorations for fun. They also freeze well, so I keep a few tucked away for a quick dessert or a surprise treat.

The buttercream is what makes these cupcakes stand out—light, smooth, and full of eggnog flavor. I usually make a little extra frosting because it’s tempting to taste while decorating.

Ingredient Notes

Use the recipe card below for exact measurements and complete instructions.

• Flour: All-purpose flour works well—spoon into your measuring cup and level off for accuracy.
• Butter: Salted butter is used for both cake and frosting. Bring it to room temperature so it creams smoothly.
• Eggnog: Store-bought full-fat eggnog delivers the best flavor and texture, but any variety will work.
• Nutmeg: Freshly grated nutmeg is ideal, though ground nutmeg is fine and convenient.
• Vegetable oil: A small amount keeps the cupcakes moist; canola oil is an acceptable substitute.
• Powdered sugar: Sift if lumpy to keep the frosting silky.
• Vanilla extract: A touch brightens the other flavors.

How To Make Eggnog Cupcakes

Preheat the oven to 350°F and line a 12-cup muffin tin with paper liners. Lightly spray the liners with nonstick cooking spray.

In a medium bowl, whisk together all-purpose flour, baking powder, salt, and nutmeg. In a separate large bowl, beat the room-temperature butter, granulated sugar, and vegetable oil until light and fluffy, about 3 minutes.

Add the eggs one at a time, mixing well after each, then stir in the vanilla extract. Add half of the dry ingredients and mix until almost combined. Pour in the eggnog and combine, then add the remaining dry ingredients and mix just until combined—avoid overmixing.

Scoop the batter into liners, filling each slightly more than halfway. Bake at 350°F for 18–20 minutes, or until a toothpick inserted in the center comes out clean. Transfer the cupcakes to a wire rack and cool completely before frosting.

Eggnog Buttercream

Beat room-temperature butter until fluffy. Add two cups of powdered sugar and beat to combine. Mix in eggnog, vanilla, a pinch of salt, and nutmeg. Add the remaining powdered sugar and beat until the frosting is smooth and pipeable. If the frosting is too thick, add a teaspoon of eggnog at a time; if too thin, add more powdered sugar.

When cupcakes are completely cool, frost with a piping bag or a knife. Finish with a light dusting of nutmeg, festive sprinkles, or other holiday decorations.

Make-Ahead, Storing and Freezing

Store: Keep frosted cupcakes in an airtight container in the refrigerator for up to 3 days. Bring to room temperature before serving for the best texture and flavor.

Freeze: These freeze very well. Freeze unfrosted or flash-freeze frosted cupcakes on a baking sheet for about an hour, then wrap individually and place in an airtight container for up to 3 months. Thaw at room temperature before serving.

Make-Ahead: Bake the cupcakes ahead of time and store unfrosted at room temperature for a day or two. Keep the frosting refrigerated and bring it to room temperature before whipping and using.

Substitutions and Variations

• Chocolate version: Stir 1/4 cup cocoa powder into the dry ingredients for a chocolate eggnog cupcake.
• Rum extract: Substitute half the vanilla with rum extract for a classic eggnog note.
• Mini cupcakes: Use a mini muffin tin and reduce bake time to 10–12 minutes.
• No frosting: Dust the cooled cupcakes with powdered sugar and nutmeg for a lighter option.

Troubleshooting

Dense cupcakes: Overmixing the batter can make cupcakes dense. Mix just until combined. Also check that your baking powder is fresh.

No nutmeg? Nutmeg is characteristic for eggnog flavor, but cinnamon or pumpkin pie spice can be substituted if needed.

Grainy frosting: This usually means the butter wasn’t soft enough. Let butter reach room temperature before mixing. If the frosting is already made, warm the mixing bowl slightly while beating to smooth it out.

Recipe Tips

• Use room-temperature butter and eggs for a smoother batter and lighter crumb.
• Fill liners just over halfway so cupcakes rise without spilling over.
• Decorate with festive sprinkles or crushed candy canes for a holiday touch.
• Ensure cupcakes are completely cool before frosting to prevent the buttercream from melting.
• Full-fat eggnog gives the best flavor and texture in both cake and frosting.

These eggnog cupcakes capture cozy Christmas flavors in a soft, sweet package. They’re simple to make and perfect for spreading holiday cheer at parties, family gatherings, or whenever you crave classic eggnog in dessert form.
