Eggnog Mug Cake is a light and fluffy Christmas mug cake, comes together in a few minutes and is SIX ingredients! It's the perfect snack for the holidays!
Sometimes it's hard to drink ALL the eggnog, as much as I love it. So I make desserts like Eggnog Rice Pudding and mug cake.

Eggnog mug cake is one of many decent lazy snacks I make. Any mug cake in general really because it takes 60- 90 seconds in the microwave. This is Christmas cake in a mug, super festive just like my Caramel Stuffed Pumpkin Mug Cake.

What To Expect
- Taste: It's a sweet, soft eggnog cake with vanilla and eggnog as the flavoring. It's simple but effective.
- Ease: This is a beginner-level recipe with 6 ingredients and whatever toppings you'd like.
- Time: It takes less than 5 minutes to whip up the mug cake. I like to make 3 or 4 at a time for our family.
🛒 Key Ingredients

- Sugar - even though eggnog is sweet, it needed a little more sugar (white granulated) to make it taste like cake. You can always use a little less if that's what you like!
- Eggnog - I use whatever store brand I can find. If you want to use one that has more cinnamon spice in it, go for it!
- Toppings - optional toppings are chocolate chips, whipped cream, strawberries, Christmas sprinkles, etc.
See the recipe card below for full information on ingredients and quantities.
✏️ Substitutions & Variations
- Sugar - white granulated sugar can be swapped out with brown sugar for more flavor or coconut sugar.
- Vanilla Extract - swap out with rum extract for even more eggnog flavor.
🧑🍳 Instructions

- Step 1. In an 8 or 12 oz. microwave safe mug, or bowl, combine eggnog, vanilla, and sugar.

- Step 2. On top of wet ingredients, combine flour, baking powder, and a pinch of salt. Mix until combined and no flour pockets left. Don't over mix.

- Step 3. Microwave for one minute and 15 seconds, more if needed.

- Step 4. Top with fun toppings: whipped cream, cinnamon, chocolate chips, strawberries, whatever you'd like!
📌 Top Tips & Hacks
- Don't overcook - usually 1 minute and 15-20 seconds is perfect for us, sometimes smaller microwaves require a little longer.
- Make sure to mix the wet ingredients first and then add the dry ingredients, it makes it easier to avoid flour pockets in your cake.
- Use at least an 8 oz mug or bowl, any smaller and it will overflow in the microwave. Been there done that.

❓Frequently Asked Questions
Either the baking powder was overmixed, or the cake was cooked too long.
There are no eggs in this recipe, so you can take a risk and eat it if you are comfortable with it.
If an inserted toothpick comes out clean, the mug cake is done.
When you're finished eating it, you can fill the mug with water and let it soak for a few hours. It should be much easier to clean after soaking.

This recipe makes delicious mug cakes! I did as some other commenters mentioned - drizzled more egnog over the cake with that generous sprinkle of nutmeg. Hate we are out of eggnog til next November.

Trying this out before a party I'm hosting and oh boy. This mug cake is absolutely incredible! I'm so excited to share this with friends.
We poured some eggnog on top after we topped it off with cinnamon, mini chocolate chips, and whipped cream. It made it so moist and extra eggnoggy, the way we like it!
