My birthday cake overnight oats are like eating dessert for breakfast. With rainbow sprinkles and vanilla notes, it makes every morning worth celebrating!

Welcome back to another episode of Dessert for Breakfast! So far we've covered brownies, sugar cookies, and so many more. Since my own birthday is coming up, I wanted to combine two of my favourite things- vanilla cake and oatmeal- for the ultimate breakfast: birthday cake overnight oats.
These oats are creamy, filling, and just sweet enough for breakfast. Thanks to the almond extract, it has that signature birthday cake flavour that we all know and love. Truly the best way to start off my birthday!
P.S. It doesn't have to be your birthday to enjoy this recipe. Birthday cake overnight oats are a fun way to celebrate any morning 😉
Why This Dietitian Loves This Recipe
Let me tell you why you NEED these birthday cake overnight oats all year round!
- Easy meal prep. Overnight oats are a staple meal prep breakfast in my house. So easy for busy mornings.
- Super filling. Thanks to a whopping 8g of fibre and 35g of protein, these oats will keep you full and satiated until lunch.
- Fun for kids. I know a lot of kids have a hard time enjoying oatmeal, but these oats are so flavorful and have the perfect amount of sweetness for them. Plus, a little sprinkle action makes any breakfast more exciting!
Ingredients
- Oats
- Chia seeds
- Vanilla protein powder
- Vanilla Greek yogurt
- Milk
- Almond extract
- Vanilla extract
- Honey
- Sprinkles
Instructions
In a mason jar or container add oats, chia seeds, and vanilla protein powder (if using).
Add in Greek yogurt, milk, almond extract, vanilla extract and honey (if using) and stir to combine. Mix in sprinkles.
Add the lid to the jar and place in the fridge for at least 2 hours or overnight. In the morning, top with additional yogurt (or whipped cream) if desired and enjoy!
Substitutions and Variations
To make gluten-free: Use certified gluten-free oats and sprinkles.
To make dairy-free: Use dairy-free vanilla yogurt and milk. Note that the final product will likely be lower in protein without Greek yogurt.
To make vegan: Use dairy-free vanilla yogurt and milk. Swap the honey for maple syrup.
To make nut-free: If you are sensitive to almond extract, you can omit it. It won't have as strong of a "birthday cake" flavour, but will still be delicious!
Missing an ingredient? Try these:
- Vanilla Greek yogurt: Use plain Greek yogurt and mix in ½ teaspoon honey
- Protein powder: Feel free to omit if you don't have any. It won't change the texture very much.
- Sprinkles: These are just here for colour and fun! Leave them out if you like.
For an extra boost of nutrition, top with berries and hemp hearts!
Equipment
- Mason jar
Storage
These birthday cake overnight oats can be stored in an airtight container or jar for up to 5 days in the fridge. The longer they sit the thicker they get, so feel free to add extra milk and give it a stir until they reach your desired consistency.
Top Tip
When mixed with liquid for long periods of time, the colours of sprinkles tend to run. This will not affect the taste at all- however, if you wish to avoid it, simply add the sprinkles in the morning before eating.
I also strongly recommend not skipping the almond extract. It seems like a small amount, but it's key for the classic "birthday cake" flavour.
Frequently Asked Questions
The flavour of ‘birthday cake’ is pretty broad and general, however I tried to go for a classic confetti cake. I find the mix of the vanilla Greek yogurt, vanilla extract and almond extract create a taste similar to the classic cake flavour. Although these might not taste EXACTLY like a slice of birthday cake they taste pretty similar to cake batter in my opinion!
Yes! The beauty of overnight oats is they require NO hands on prep time in the morning, simply make them the night before, store in the fridge and they are ready to be eaten as is in the morning.
My personal favourites recently are Sweetapolita- they have so many different colours and options!
I love using the Smooth Vanilla protein from Nuzest in these oats. You can try it out with my code NOURISHEDBYNIC!
