Ingredients for Cake Batter Overnight Oats
- Rolled Oats: The foundation of our recipe. Use old fashioned rolled oats for the best chewy and creamy texture.
- Milk: I use regular dairy milk, but any kind works! Almond, soy, or oat milk are great for a dairy free version.
- Greek Yogurt: This is my secret for an ultra creamy texture and a great protein boost. Vanilla or plain both work well.
- Yellow Cake Mix: Just a couple of tablespoons of dry cake mix add that authentic funfetti cake batter flavor. Ensure it’s safe for raw consumption or heat treat it first (see notes).
- Maple Syrup: For a touch of natural sweetness. You can adjust the amount to your liking or substitute with honey or agave.
- Vanilla Extract: This enhances the cake flavor, giving it that classic vanilla warmth.
- Butter or Almond Extract: A tiny drop of one of these is optional but highly recommended to get that rich, buttery cake taste.
- Sprinkles: It’s not birthday cake without them!Rainbow jimmies work best as they don’t bleed their color as much as nonpareils.
- Chia Seeds (Optional): For an extra boost of fiber and omega 3s, and to help thicken the oats.
Substitutions: For a gluten free option, simply use certified gluten free rolled oats and a gluten free yellow cake mix. For a vegan version, use plant based milk, a dairy free yogurt, and maple syrup.

How to Make Cake Batter Overnight Oats
One of the first things I learned from my grandmother was that the best recipes are often the simplest. She believed that cooking should be about joy, not stress, and this recipe is a perfect testament to that philosophy. It’s a mix and chill recipe, which means it’s practically foolproof and perfect for getting the kids involved in the kitchen. There’s no heat, no complicated steps, just the simple joy of mixing ingredients and anticipating the delicious breakfast to come. It’s these kinds of recipes, the ones that simplify life while adding a touch of something special, that I love sharing the most. They become the fabric of our family memories, the tastes we associate with comfort, love, and home. This is more than a no bake recipe; it’s a gateway to easy, joyful mornings.
Step-by-Step Instructions
- First, grab a medium sized bowl or a large jar with a lid. Combine your wet ingredients: the milk, Greek yogurt, maple syrup, vanilla extract, and the optional butter or almond extract. Whisk them together until they are smooth and completely combined. Making sure the yogurt is fully mixed in is key to getting that consistently creamy texture in every bite.
- Next, it’s time for the dry ingredients. Add the rolled oats, the dry cake mix, and the optional chia seeds directly into the bowl with the wet mixture. Stir everything together until just combined. You don’t want to overmix, just ensure that all the oats are coated and beginning to absorb the liquid.
- Now for the most important part: the fun! Gently fold in the sprinkles. Be gentle here! If you stir too aggressively, the colors can bleed into the oat mixture. I like to do this right at the end to keep the colors as bright and distinct as possible, which makes it look so much more appealing in the morning.
- Once everything is mixed, transfer the mixture into airtight containers or jars. I love using single serving mason jars because they are perfect for a grab and go breakfast and they look so cheerful lined up in the fridge. Seal the jars tightly.
- Finally, place the jars in the refrigerator for at least 4 hours, but for the best results, leave them overnight. This time allows the oats to soften and absorb all those delicious cake batter flavors, resulting in a thick, creamy, and dreamy breakfast. The waiting is the hardest part, but it’s so worth it!
Pro Tips & Variations
Over the years, my family and I have made this Cake Batter Overnight Oats recipe countless times, and we’ve picked up a few tricks along the way to make it absolutely perfect. Part of the fun of being a home cook is experimenting and finding what works best for you and your family. These little adjustments can elevate a good recipe to a great one. Whether you’re looking for a richer flavor, a different texture, or ways to adapt it to your dietary needs, these tips and variations will help you master this delightful breakfast. For more inspiration on overnight oats, I love the creativity shown over at Pumpkin ‘N Spice. It’s always fun to see how other food lovers approach a recipe.
- Heat Treat Your Flour/Cake Mix: Since we aren’t cooking this, if you’re using cake mix or flour, it’s a good practice to heat treat it to eliminate any potential bacteria. Simply spread the dry mix on a baking sheet and bake at 350°F (175°C) for about 5 minutes. Let it cool completely before using.
- Wait to Add Sprinkles: If you want your sprinkles to stay vibrant and crunchy, stir them in right before serving. While mixing them in beforehand is fine, they will soften and their colors can bleed into the oats overnight. For that picture perfect look, a fresh sprinkle on top is the way to go.
- Achieve the Perfect Consistency: The ideal thickness of overnight oats can be a personal preference. If you wake up and find your oats are thicker than you’d like, simply stir in an extra splash of milk until you reach your desired consistency. If they seem too thin, you can add a tablespoon of chia seeds or more oats and let it sit for another 30 minutes.
Variations:
- Chocolate Cake Batter: For the chocolate lovers in your life, swap the yellow cake mix for a chocolate cake mix and add a tablespoon of cocoa powder. It turns into a rich, decadent breakfast that tastes like chocolate cake.
- Strawberry Cake Batter: Use a strawberry cake mix and top with fresh, sliced strawberries for a fruity twist. It reminds me of our popular Strawberries & Cream Overnight Oats but with a cakey flavor.
- Vegan Funfetti: This recipe is easily made vegan! Use your favorite plant based milk (almond or oat milk works wonderfully), a dairy free vanilla yogurt, and check that your cake mix and sprinkles are vegan. The result is just as creamy and delicious.
Serving Suggestions
One of my favorite things about cooking is the final step: serving the dish and seeing the smiles it brings. Presentation can turn a simple meal into a special occasion, and these Cake Batter Overnight Oats are so fun to dress up. In our house, we treat our overnight oats jars like little breakfast sundaes. Setting up a small ‘toppings bar’ on the weekend is a fantastic way to get everyone involved and lets each person customize their breakfast just the way they like it. This is where you can get really creative and add different textures and flavors that complement the creamy, sweet oats. Think about what you’d put on a slice of birthday cake and bring those ideas to your breakfast bowl! It’s another chance to create a small moment of joy and connection before the day officially begins. Whether you’re enjoying a quiet morning alone or feeding a bustling family, these serving ideas will make your breakfast even more memorable.
- Fresh Berries: The slight tartness of fresh raspberries, strawberries, or blueberries beautifully cuts through the sweetness of the cake batter flavor. They also add a wonderful pop of natural color.
- A Dollop of Cream: For an extra decadent treat, top your oats with a spoonful of whipped cream, a dollop of cool whip, or even some extra vanilla Greek yogurt. It enhances the creamy texture and makes it feel even more like a dessert.
- A Sprinkle of Crunch: Texture is so important! Add a sprinkle of chopped nuts like pecans or almonds, some granola, or even some crushed animal crackers or golden Oreos right before serving for a delightful crunch.
- More Sprinkles: Can you ever have too many sprinkles? I don’t think so! Add an extra dash of colorful sprinkles on top right before you dig in for that perfect funfetti look and feel.
- Creative Drizzles: A light drizzle of melted white chocolate or a touch of caramel sauce can elevate this breakfast into a true masterpiece. For a similar vibe with a different flavor, check out our S’mores Overnight Oats recipe.
Storage & Reheating for Cake Batter Overnight Oats
One of the absolute best features of this recipe is that it’s designed for your convenience. As a dad and husband, I know that anything I can do to get ahead of the morning rush is a huge win. These Cake Batter Overnight Oats are the star of my meal prep strategy. I typically make a batch on Sunday evening, and just like that, breakfast for the busiest days of the week is sorted. Storing them correctly is key to making sure that the last jar of the week is just as delicious as the first.
For storage, simply keep the oats in airtight containers in the refrigerator. Individual glass jars with lids are perfect for this. They will stay fresh, creamy, and delicious for up to 4 to 5 days. The flavor actually gets even better as the oats have more time to soak everything in. I do not recommend freezing these oats, as the freezing and thawing process can negatively affect the texture of the oats and the yogurt, making them watery and less creamy. Since this is a cold breakfast, there’s no reheating required. They are meant to be enjoyed chilled, straight from the refrigerator, making them the ultimate effortless and delicious start to your day.
FAQ about Cake Batter Overnight Oats
Can I use a different type of oats for this recipe?
I highly recommend using old fashioned rolled oats. They provide the perfect creamy yet chewy texture. Steel cut oats will not soften enough overnight and will result in a very tough, chewy breakfast. Quick or instant oats will become too soft and mushy.
Is this cake batter oats recipe actually healthy?
Yes, absolutely! While it tastes like an indulgent treat, it’s built on a foundation of wholesome ingredients. You get fiber from the oats and chia seeds, and a great amount of protein from the Greek yogurt, which keeps you full. You also have complete control over the amount of sweetener you add, making it a much healthier choice than store bought cereals or actual cake.
How can I make this without using a boxed cake mix?
That’s a great question! If you prefer to avoid boxed cake mix, you can create a similar flavor profile from scratch. Instead of the 2 tablespoons of cake mix, use 2 tablespoons of oat flour (or all purpose flour, heat treated), and add about 1/4 teaspoon of almond extract or butter extract along with the vanilla. This will mimic that classic, buttery cake batter flavor.
My oats seem very thick/thin. How can I fix it?
The consistency of your oats can vary depending on the type of yogurt or protein powder you use. If you open the jar and find it’s too thick for your liking, just stir in a splash of milk until it’s perfect. If it seems a bit thin, you can add another teaspoon of chia seeds and let it sit for about 20-30 minutes to thicken up.
