    jar of oats with text overlay "birthday cake overnight oats".

    If you want to feel like you're eating dessert for breakfast, then you need to try these Birthday Cake Overnight Oats! These cake batter oats are packed with healthy ingredients like chia seeds & plant-based yogurt, but taste just like your favorite funfetti cake.

    two jars with rainbow sprinkle oats topped with whipped cream and more sprinkles.

    If there is one thing I am, it is a girl who loves funfetti everything. Take my Vegan Funfetti Cupcakes, Funfetti Sugar Cookies, and Vegan Lofthouse cookies as just a few examples that rainbow sprinkles truly make everything better!

    These birthday cake overnight oats are a healthier treat made with rainbow sprinkles and can even be enjoyed as a quick weekday breakfast!

    Ingredients:

    labeled overnight oat ingredients like oats, sprinkles, yogurt, soy milk, vanilla, almond extract, maple syrup, and chia seeds.

    Ingredient & substitution ideas:

    • Sprinkles: Not all sprinkles are vegan, so just make sure to choose ones that are if you can!
    • Yogurt: To keep these funfetti overnight oats vegan & dairy-free I used unsweetened vegan yogurt in this recipe, but using greek yogurt is another great option if you are okay with dairy.
    • Almond Extract: This is totally optional and gives these oats more of a "sugar cookie" flavor. However, they taste just as good without it!
    • Soy milk: Can be substituted 1:1 for any other plant-based milk like oat or almond milk.
    • Chia seeds: Can be substituted 1:1 for ground flaxseed.

    How to make birthday cake overnight oats

    Mix all the ingredients in one bowl

    Add the rolled oats, soy milk, vegan yogurt, chia seeds, maple syrup, vanilla bean paste, and almond extract to a bowl and mix them together.

    Then, add in the rainbow sprinkles and gently mix them in. Make sure not to overmix here or the color from the colors of the sprinkles may bleed into the batter and turn it a blue/green color.

    Add to jars & store overnight

    Add the cake batter oats to two jars and cover with a lid. I love using these weck jars, but really any container will work.

    Then, store in the fridge overnight or for at least 4 hours until the oats soften and the chia seeds absorb the liquid.

    Add toppings & enjoy!

    To top these I used vegan whipped cream and more rainbow sprinkles.

    However, you could also add almond butter as a topping as I did with my Banana Bread Overnight Oats, or more vegan yogurt as I did with my Pumpkin Pie Overnight Oats.

    How to store cake batter overnight oats:

    Overnight oats can be stored in the fridge for 3-4 days and are truly best the day after they are made.

    They do not freeze well so I recommend enjoying them within this time frame.

    I can't wait for you to try these easy & delicious Vegan Birthday Cake Overnight Oats as a fun snack or breakfast option. Enjoy!

      This recipe sounds yummy! I'll definitely have to try it! I noticed in the instructions you mentioned maple syrup but I didn't see it listed in the ingredients. How much do we need to use? Thank you!
