How to Make Birthday Cake Overnight Oats Recipe
Step 1: Mix Your Base
Start by gathering all your ingredients into a mason jar or any airtight container. Combine the rolled oats, almond milk, Greek yogurt, chia seeds, vanilla extract, sweetener, almond extract if using, and a pinch of salt. This mixture forms the creamy, flavorful foundation of your Birthday Cake Overnight Oats Recipe.
Step 2: Stir Well
Give everything a good stir until the oats and seeds are evenly coated and all the flavors are blended. This step ensures each spoonful will be as delicious as the last without any clumps or dry spots.
Step 3: Refrigerate Overnight
Seal your container tightly and let it rest in the fridge overnight. This slow soak is what turns those raw oats into a luscious, ready-to-eat breakfast that’s soft, thick, and subtly sweet.
Step 4: Add the Sprinkles
The morning of your breakfast celebration, stir your oats once more, then sprinkle on a generous handful of rainbow sprinkles. This final touch brings the playful birthday cake vibe to life with color and crunch.
Step 5: Enjoy!
Dig right in straight from the jar for convenience or transfer your oats to a bowl if you prefer a more traditional breakfast feel. Either way, you’re in for a treat that tastes just as good as it looks.
How to Serve Birthday Cake Overnight Oats Recipe

Garnishes
Beyond the rainbow sprinkles, try topping your oats with fresh berries, chopped nuts, or even a drizzle of melted white chocolate for extra indulgence. These add texture, natural sweetness, and an elegant twist that keeps your morning exciting.
Side Dishes
This oats dish pairs wonderfully with a side of sliced fruit or a small glass of freshly squeezed orange juice. The bright, juicy fruits provide a refreshing contrast to the creamy oats while keeping the meal balanced and satisfying.
Creative Ways to Present
Think beyond the jar by layering your Birthday Cake Overnight Oats Recipe with fruit compotes or whipped coconut cream in a pretty parfait glass. For an on-the-go option, add a festive reusable spoon and tuck the oats into a colorful lunch bag to brighten up your work or school mornings.
Make Ahead and Storage
Storing Leftovers
If you whip up a double batch, just keep your leftover oats refrigerated in a sealed container. They’ll stay fresh and tasty for about 2 to 3 days, so you can enjoy this birthday-inspired breakfast anytime.
Freezing
Overnight oats tend to lose their perfect texture when frozen and thawed, so it’s best to avoid freezing this recipe. You’ll get the most delicious experience fresh from the fridge.
Reheating
While the oats are best enjoyed cold or at room temperature, if you prefer warmth, gently reheat them in the microwave for about 30 seconds. Add a splash of milk if needed to loosen the texture before stirring and sprinkling on your sprinkles.
FAQs
Can I use regular milk instead of almond milk?
Absolutely! Feel free to swap in any milk you like, including cow’s milk or oat milk—the recipe is very adaptable and each choice adds its own character.
Are rainbow sprinkles necessary?
While they’re the fun, signature touch that makes this recipe feel like a birthday celebration, you can skip or substitute them with chopped nuts or coconut flakes if you want a healthier option.
Can I prepare this without Greek yogurt?
You can! Using Greek yogurt adds creaminess and protein, but if you prefer dairy-free or less tangy, simply replace it with more milk or a plant-based yogurt alternative.
How long can I store overnight oats in the fridge?
Overnight oats keep well for up to 3 days in the refrigerator when stored in an airtight container, making them perfect for meal prep.
Is this recipe suitable for weight watchers?
This recipe can fit into most healthy eating plans with its controlled portions and wholesome ingredients, but keep an eye on the sweetener and sprinkles if you want to reduce sugar intake.
