Eggnog Oatmeal Breakfast Cake

Sweeten up your mornings this holiday season 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.

Eggnog - Adds creaminess to the cake, make sure it's at room temperature before beginning.

Flour – All-purpose flour is used in this recipe.

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 2 sides of the pan. Gently grease the other two sides and then set aside.

Step 2 – Mix dry ingredients. In a medium sized bowl, add in flour, oats, cinnamon, nutmeg, cornstarch, baking soda, baking powder, and salt. Stir to combine and set aside.

Step 3 – Cream the butter and sugar. In a large bowl, add softened butter and white sugar. Beat on medium speed for 2-3 minutes until it’s light and fluffy. Make sure to scrap the sides of the bowl.

Step 4 – Add in wet ingredients. Add in the eggs, vanilla, eggnog, sour cream, and rum extract (optional). Continue mixing on medium speed. It’s okay if it is clumpy.

Step 5 – Add in dry ingredients. Mix in the dry ingredients and using a spatula, gently fold until a batter forms. Do not overmix! 

Step 6 – Bake. Spread the batter into the prepared pan evenly. In a small cup, mix together sugar, nutmeg, and cinnamon. Sprinkle that on top. This will give you a sweet crunchy top. 

Bake for 35-45 minutes. It really depends on your oven, but after 30 minutes I would start checking with a toothpick to see if it’s ready! A toothpick should come out clean.

Allow to cool, slice, and enjoy! This eggnog oatmeal breakfast cake is soo 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. I cannot emphasize this enough! It is the most accurate way of measuring your ingredients in the kitchen. This is one of my favourites.
• Do not over-mix! A big reason cakes don’t rise or turn out tough is because the batter is 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.
