Ingredients You’ll Need
-
Oats Mixture:
- 1/2 cup old-fashioned oats
- 1/2 cup milk (any kind)
- 1/4 cup plain or vanilla Greek yogurt
- 1 tablespoon chia seeds
- 1 tablespoon maple syrup or honey
- 1/2 teaspoon vanilla extract
- 1/4 teaspoon almond extract
- 1 tablespoon vanilla or birthday cake protein powder (optional)
- 1 teaspoon rainbow sprinkles (plus more for topping)
How to Make Birthday Cake Overnight Oats
Step 1: Combine the Base Ingredients
In a mason jar or airtight container, add the old-fashioned oats, milk of your choice, Greek yogurt, chia seeds, maple syrup (or honey), vanilla extract, almond extract, and protein powder if you’re using it. This order helps keep things tidy and makes stirring a breeze.
Step 2: Mix Everything Together
Give all the ingredients a good stir, making sure the chia seeds are well distributed and the powder (if using) is fully dissolved. You want the oats fully coated and everything evenly combined so you get a consistent flavor in every spoonful of your Birthday Cake Overnight Oats.
Step 3: Gently Fold in the Sprinkles
Carefully fold in one teaspoon of rainbow sprinkles. Be gentle! This keeps the colors from bleeding too much, ensuring you get those picture-perfect confetti dots when you open your jar in the morning.
Step 4: Refrigerate Overnight
Seal your container and move it to the fridge. Let the mixture chill for at least four hours, but overnight is best. This allows the oats and chia seeds to absorb the liquid, plump up, and take on that dreamy, pudding-like consistency we all crave in overnight oats.
Step 5: Stir and Top Before Serving
In the morning, give your Birthday Cake Overnight Oats a quick stir to remix the sprinkles and creamy oats, then add an extra pinch of sprinkles on top. Enjoy your oats chilled, or let them warm up at room temperature for 10-15 minutes if you prefer. Every bite is like a sweet celebration to start your day!
How to Serve Birthday Cake Overnight Oats

Garnishes
To really nail the cake-for-breakfast experience, top your oats with a generous flurry of rainbow sprinkles just before serving. You can also add a dollop of whipped cream, sliced strawberries, or even a few slivers of toasted almonds for an extra-special finish that’ll make your bowl feel straight out of a bakery window.
Side Dishes
Birthday Cake Overnight Oats are lovely on their own, but they also pair well with a side of fresh fruit—think juicy berries or sliced bananas. For a satisfying brunch spread, serve them alongside a cup of coffee, a tall smoothie, or a small bowl of mixed nuts to enhance the nourishment and flavor variety.
Creative Ways to Present
If you’re making these oats for a crowd or a special birthday morning, try layering them in clear parfait glasses with extra yogurt and fruit, or serve them in mini mason jars with matching festive spoons. For a true party touch, tie a colorful ribbon around the jar or add a playful cupcake topper to each serving. Every little detail turns your Birthday Cake Overnight Oats into a memory-making breakfast.
Make Ahead and Storage
Storing Leftovers
Any leftover Birthday Cake Overnight Oats can be kept in the fridge for up to three days. Just be sure they’re in a sealed jar or container. The oats will continue to soften, and the flavors meld even more the longer they sit—just stir well before serving for the best texture.
Freezing
While these oats are technically freezer-friendly, freezing can affect their creamy texture and the look of your sprinkles. If you need to freeze them, use a freezer-safe jar, leave a little space at the top, and thaw overnight in the fridge. Give everything a nice stir before eating, and add fresh sprinkles just before serving to brighten them up.
Reheating
Birthday Cake Overnight Oats are designed to be enjoyed cold or at room temperature, but if you crave a warmer start, simply microwave them in a microwave-safe bowl in 20-second bursts until they reach your preferred temperature. Add a splash of milk to loosen them, and don’t forget your party-perfect sprinkle topping afterward!
FAQs
Can I use steel-cut oats instead of old-fashioned oats?
Steel-cut oats have a much firmer texture and won’t soften properly with just an overnight soak, so stick with old-fashioned oats for the creamiest result in your Birthday Cake Overnight Oats.
What non-dairy options work well in this recipe?
Almond, oat, or coconut milk all work beautifully, as do plant-based yogurts like coconut or almond. Choose your favorites—this recipe is super adaptable whether you’re dairy-free or just mixing it up.
Do I have to use protein powder?
Not at all! The protein powder is totally optional. Leave it out if you prefer, and your oats will still be packed with flavor and plenty satisfying thanks to the Greek yogurt and chia seeds.
Will the sprinkles dissolve or bleed?
Some bleeding can happen, but folding in the sprinkles gently and topping with fresh ones before serving helps maintain their festive rainbow look. For the most vibrant finish, use high-quality rainbow sprinkles.
Can I double or triple the recipe for meal prep?
Absolutely! Scale up the ingredients and mix your Birthday Cake Overnight Oats in a large bowl, then divide into single-serving jars for easy grab-and-go breakfasts all week long. It’s a total time-saver and guarantees a little celebration every morning.
