Ingredients
- 1 cup old-fashioned rolled oats (do not use instant oats, they get too mushy)
- 1 cup milk (any milk works: almond, oat, whole, or 2%)
- 1/2 cup plain Greek yogurt (vanilla yogurt also works and makes it even sweeter)
- 1 tablespoon chia seeds (flaxseeds work as a substitute)
- 2 tablespoons maple syrup or honey (adjust to your taste)
- 1 and 1/2 teaspoons pure vanilla extract (this is key for that birthday cake flavor)
- 1/4 teaspoon almond extract (optional but adds amazing depth)
- 2 tablespoons rainbow sprinkles (use nonpareils or jimmies, whichever you prefer)
- Pinch of salt
- Optional toppings: whipped cream, extra sprinkles, fresh fruit, or a drizzle of white chocolate
How to Make Birthday Cake Overnight Oats
- Grab your jars or containers. Mason jars work perfectly for this recipe. You want something with a lid so the oats stay fresh overnight.
- Combine the oats and chia seeds. Add half a cup of oats and half a tablespoon of chia seeds to each jar. Stir them together so they are evenly mixed.
- Mix the wet ingredients. In a separate small bowl, whisk together the milk, Greek yogurt, maple syrup, vanilla extract, almond extract, and salt. This creates the creamy base that soaks into the oats overnight.
- Pour the wet mixture over the oats. Divide the liquid mixture evenly between your two jars. Give everything a good stir to combine.
- Add the sprinkles. Stir in one tablespoon of sprinkles into each jar. Some of the color will bleed slightly overnight, which is totally normal and still looks beautiful.
- Seal and refrigerate. Put the lids on your jars and place them in the fridge. Let them sit for at least six hours, but overnight works best. The oats will absorb the liquid and become thick and creamy.
- Add your toppings in the morning. When you are ready to eat, give the oats a stir. Add a dollop of whipped cream, a sprinkle of fresh rainbow jimmies, or anything else your heart desires.
- Enjoy cold or slightly warmed. These are traditionally eaten cold, but you can microwave them for 60 to 90 seconds if you prefer a warm breakfast.
Pro Tips for Perfect Birthday Cake Overnight Oats
Always use old-fashioned rolled oats, not quick oats or steel-cut oats. Rolled oats absorb just the right amount of liquid and give you that perfect chewy yet creamy texture.
Do not skip the vanilla extract. It is the star of the show and what makes these oats actually taste like birthday cake. Use pure vanilla extract, not imitation, for the best flavor.
Add toppings right before eating. If you add whipped cream or extra sprinkles the night before, they will melt and get soggy by morning. Keep those toppings fresh by adding them at the last minute.
Taste your oats before refrigerating. Different milk and yogurt brands have varying levels of sweetness. Adjust the maple syrup to your preference so you wake up to a breakfast you truly love.
Give the oats a good stir in the morning before eating. Sometimes the liquid settles at the bottom, and a quick stir brings everything back together beautifully.
Flavor Variations
Strawberry Birthday Cake: Add two tablespoons of strawberry jam to the wet mixture and top with fresh strawberry slices in the morning. It tastes like strawberry shortcake birthday cake.
Chocolate Birthday Cake: Stir in one tablespoon of cocoa powder and top with mini chocolate chips. You can also add a drizzle of chocolate syrup on top for extra indulgence.
Lemon Birthday Cake: Add one teaspoon of fresh lemon zest and swap out the almond extract for lemon extract. Top with lemon curd for an amazing citrus twist.
Protein Birthday Cake: Add one scoop of vanilla protein powder to the wet mixture. Reduce the milk slightly so the oats are not too thin. This version packs around 25 to 30 grams of protein per serving.
Vegan Birthday Cake: Use oat milk or almond milk, swap the Greek yogurt for coconut yogurt, and use maple syrup instead of honey. Check that your sprinkles are vegan-friendly as well.
Storage Tips
These overnight oats stay fresh in the refrigerator for up to five days. That makes them ideal for Sunday meal prep so you have breakfast ready Monday through Friday.
Always store them with the lid tightly sealed. If the oats look a little thick after a couple of days, just add a splash of milk and stir to loosen them up.
Do not freeze overnight oats. The texture changes significantly when thawed and becomes watery and unpleasant. They are best enjoyed cold from the fridge.

Frequently Asked Questions
What are birthday cake overnight oats?
Birthday cake overnight oats are a no-cook breakfast made with rolled oats, milk, Greek yogurt, vanilla extract, and rainbow sprinkles. They are mixed together the night before and refrigerated so the oats soften into a thick, creamy, cake-flavored breakfast by morning.
How long do overnight oats need to sit before eating?
Overnight oats need to sit for at least six hours in the fridge. Most people prepare them before bed and eat them in the morning, which is usually eight to ten hours. The longer they sit, the creamier they become.
Can I make overnight oats without yogurt?
Yes, you can make overnight oats without yogurt. Simply increase the milk to 1 and 1/4 cups per serving. The oats will be slightly less thick and creamy but will still taste delicious. Coconut cream is another great substitute for yogurt if you want extra richness.
Are overnight oats healthy?
Yes, overnight oats are very healthy. They are high in fiber, which supports digestion and keeps you feeling full. They also provide a good source of protein, especially when made with Greek yogurt. Oats contain beta-glucan, a type of fiber that is known to support heart health.
Can I use quick oats instead of rolled oats?
You can use quick oats in a pinch, but the texture will be mushier and less satisfying than rolled oats. Old-fashioned rolled oats are strongly recommended for the best consistency. Steel-cut oats can also work but require a longer soaking time of at least 12 hours.
