Sweeten up your Christmas morning with a slice of delicious eggnog oatmeal breakfast cake! It’s got eggnog, hearty oats, and loads of cinnamon sugar in every bite. This is a classic recipe for the season that I just adore!
Around Christmas time I love to use eggnog to bake - it is such a treat.
Baking with eggnog makes your sweets extra moist. This breakfast cake can be eaten for breakfast (duh), as a snack, or after dinner for a little sweet treat.
It's got soft spices paired with the creamy flavour of eggnog all in one. The oats add an incredible texture, and it's sprinkled with some cinnamon sugar on top for a little extra yum.

Step by step instructions
Here is how to make and bake this eggnog breakfast oatmeal cake. You will need a 9×9 baking pan lined with parchment paper, 2 mixing bowls, a spatula, and an electric handheld mixer.
Step 1 – Prep. Grease the pan. For easy removal of the cake, place parchment paper on the bottom and overhanging from 2 sides of the pan. Then gently grease the other two sides and then set aside.
Step 2 – Mix dry ingredients. In a medium sized bowl, add in the dry ingredients. Stir to combine and set aside.
Step 3 – Cream the butter and sugar. In a large bowl, add the butter and white sugar. With an electric mixer, mix for 2-3 minutes on medium speed. Make sure to scrap the sides of the bowl when needed, the mixture will be light and fluffy.
Step 4 – Add in wet ingredients. Add in the wet ingredients. Continue to mix for another 2-3 minutes on medium speed. It’s okay if the mixture curdles.
Step 5 – Add in dry ingredients. With a spatula, gently fold the ingredients together until a batter forms. Do not over-mix!
Step 6 – Bake. Spread the batter into the prepared pan. In a small cup, mix together sugar, nutmeg, and cinnamon. Sprinkle evenly on top.
Bake the cake for 35-45 minutes. It really depends on your oven, but after 30 minutes I would insert a toothpick in the middle to see if it’s ready! A toothpick should come out clean. If it has wet batter, it is not ready.
Allow to cool, slice, and enjoy! This eggnog oatmeal breakfast cake is so good! It stays good on the counter for a day in an airtight container, and in the refrigerator for 5 days!
Expert Baking Tips
Here are a few expert baking tips from my kitchen to yours
- Use a gram scale. You can toggle between cups and grams in the recipe card. This is one of my favourites.
- Do not over-mix! A big reason cakes work is because the batter gets over-mixed. Once you see no flour streaks, stop mixing.
- To make ahead of time: Bake, cool, slice, and store in an airtight container or wrap in foil/saran wrap.
