How to Make Birthday Cake Overnight Oats Recipe
Step 1: Combine the Base Ingredients
Start by grabbing a mason jar or any airtight container. Add the rolled oats, almond milk, and plain Greek yogurt. These three ingredients form the creamy foundation that will soak up all the delicious flavors overnight, making every bite smooth and rich.
Step 2: Add the Flavor Boosters
Mix in the chia seeds, vanilla extract, maple syrup or honey, almond extract if you’re using it, and a pinch of salt. This combination is what makes the oats taste just like birthday cake in your mouth — sweet, nutty, and wonderfully aromatic.
Step 3: Mix Well and Refrigerate
Stir everything thoroughly until all the ingredients are evenly distributed. Seal your jar or container tightly to prevent any fridge odors from sneaking in. Then, pop it into the fridge and let it work its magic overnight. The oats will soften perfectly, and the chia seeds will help thicken the mixture to just the right consistency.
Step 4: Top with Sprinkles and Enjoy
The moment you’ve been waiting for — in the morning, give your oats a good stir to refresh the texture. Sprinkle the rainbow sprinkles on top to bring that colorful, festive look and a bit of joyful crunch that truly makes this a Birthday Cake Overnight Oats Recipe worth celebrating.
How to Serve Birthday Cake Overnight Oats Recipe

Garnishes
While the rainbow sprinkles are the star garnish, you can also add fresh berries, a dollop of whipped cream, or even a few chopped nuts if you like a little crunch. These additions enhance both texture and flavor, making every spoonful more exciting.
Side Dishes
This Breakfast Cake Overnight Oats Recipe pairs beautifully with a side of fresh fruit salad or a warm cup of herbal tea. Both balance the sweet richness of the oats and round out your morning with natural freshness.
Creative Ways to Present
Serve your oats in a clear glass jar to showcase the layers of creamy oats and colorful sprinkles. You can also layer it with crushed graham crackers or sprinkle edible glitter on top for an extra festive vibe. For a grab-and-go option, keep it sealed in a mason jar with a cute ribbon around it—it’s perfect for gifting or prepping ahead for busy mornings.
Make Ahead and Storage
Storing Leftovers
If you happen to make a double batch, leftovers can be stored in the refrigerator in an airtight container for up to 3 days. The texture deepens over time, so give it a quick stir before serving to bring back that creamy consistency.
Freezing
Freezing overnight oats is not usually recommended because the texture can change, with oats becoming a bit mushy upon thawing. However, if you want to try it, freeze in a sealed container for up to a month and thaw overnight in the fridge before eating.
Reheating
Because the magic of this Birthday Cake Overnight Oats Recipe happens in the cold soak, it’s best enjoyed chilled. But if you prefer it warm, heat gently in the microwave for 30 to 45 seconds, stirring halfway through, so it warms evenly without losing that creamy texture.
FAQs
Can I use regular milk instead of almond milk?
Absolutely! You can substitute any milk you prefer, such as cow’s milk, oat milk, or soy milk. The oats will still soak up the flavors beautifully, but almond milk adds a subtle nuttiness that complements the birthday cake vibe.
Are the rainbow sprinkles necessary?
While not essential for taste, rainbow sprinkles are what give this recipe its festive birthday cake flair. You can substitute with chopped nuts or colorful fruit if you want a healthier option, but the sprinkles add that classic playful touch.
Can I make this recipe vegan?
Yes! Simply swap the Greek yogurt for a plant-based yogurt and use maple syrup instead of honey. The texture and taste will remain just as delightful, keeping it a delicious and inclusive Birthday Cake Overnight Oats Recipe.
How long does it take to prepare?
The prep time is only about five minutes! The real magic happens overnight, so you wake up to a ready-made birthday-inspired breakfast that feels indulgent but requires minimal effort.
Can I add protein powder?
Definitely! Adding a scoop of vanilla or unflavored protein powder can boost the protein content. Just mix it in along with the oats and other ingredients to keep the creamy texture intact.
