Single Serve Birthday Cake Baked Oats 35g Protein

These birthday cake baked oats taste like soft funfetti cake batter, but they are made for breakfast. This single-serving baked oats recipe has 35 grams of protein and bakes into a fluffy, cake-like bowl in about 30 to 40 minutes.

Birthday cake baked oats are a high-protein breakfast made by blending oats into a smooth batter, baking them until fluffy, and finishing them with creamy Greek yogurt icing and colorful sprinkles. The texture is closer to cake than regular oatmeal, which is exactly why this recipe became so popular.

This version keeps the funfetti flavor front and center while still being filling enough for a real breakfast. Almond extract gives the oats that classic birthday cake taste, protein powder boosts the nutrition, and a ripe banana adds natural sweetness and moisture. The result is warm, soft, sweet, and satisfying without feeling like a heavy dessert first thing in the morning.

Why You’ll Love These Birthday Cake Baked Oats

Ingredients You’ll Need

Exact measurements are included in the recipe card below. These notes explain what each ingredient does and how to make the best birthday cake baked oats.

For the baked oats:

• Gluten-free rolled oats — rolled oats or quick oats both work well because they blend into a smooth flour. Avoid steel-cut oats, which will not create the same cake-like texture.
• Ripe banana — adds moisture and natural sweetness. A banana with brown spots will give the best flavor.
• Egg — helps the oats rise and gives structure. For a vegan option, use a flax egg made with 1 tablespoon ground flaxseed and 3 tablespoons water.
• Baking powder — helps the baked oats become light and fluffy instead of dense.
• Cashew butter — adds richness and a creamy cake-batter flavor. Almond butter or peanut butter can be used, but they will slightly change the taste.
• Almond extract — the key ingredient for birthday cake flavor. Vanilla extract can be used, but almond extract gives the oats a more classic funfetti taste.
• Almond milk — keeps the batter smooth. Any milk you enjoy can be used.
• Vanilla or cake-flavored protein powder — adds sweetness, flavor, and most of the protein in this recipe.
• Rainbow sprinkles — folded in at the end for the funfetti look and birthday cake feel.

For the icing:

• Plain Greek yogurt — creates a creamy topping and adds extra protein.
• Sweetener of choice — powdered sugar gives a thicker icing texture, while honey or maple syrup makes a thinner drizzle.
• More sprinkles — for a colorful finish.

How to Make Birthday Cake Baked Oats

1. Preheat the oven. Set the oven to 350°F (175°C) and lightly grease one 8-ounce ramekin or small oven-safe dish.
2. Blend the oats. Add the oats to a blender and blend until they become a fine flour.
3. Add the remaining batter ingredients. Add the banana, egg, baking powder, cashew butter, almond extract, almond milk, and protein powder. Blend until the batter is smooth.
4. Fold in the sprinkles. Stir the sprinkles in by hand. Do not blend them, or they may dissolve and discolor the batter.
5. Bake. Pour the batter into the prepared ramekin and bake for 25 to 30 minutes, or until the top is set and a toothpick inserted slightly off-center comes out mostly clean.
6. Prepare the icing. While the oats bake, stir together Greek yogurt and your sweetener of choice until smooth.
7. Cool and top. Let the baked oats cool for about 5 minutes, then spoon the icing over the top and finish with more sprinkles.

Tips for the Best Birthday Cake Baked Oats

• Use almond extract for the best flavor. It gives the oats that unmistakable cake-batter taste.
• Do not overbake. Baked oats continue to firm up slightly as they cool, so remove them once the top is set.
• Use a ripe banana. A sweeter banana improves both flavor and texture.
• Fold the sprinkles in gently. Blending them can cause the colors to bleed into the batter.
• Test slightly off-center. The middle may stay a little moist because of the banana, so test near the center rather than directly in the wettest spot.
• Let the oats cool before icing. If the oats are too hot, the yogurt topping will melt quickly.
• Adjust for your oven. If your baked oats turn out dry, try lowering the oven temperature to 340°F and baking a little longer, or check them earlier at 350°F.

Storage and Reheating

Birthday cake baked oats can be stored in an airtight container in the refrigerator for 3 to 4 days. If you are making them ahead, store the Greek yogurt icing separately and add it after reheating.

To reheat: Microwave for 30 to 45 seconds with a small splash of milk, or warm in a 350°F oven for 10 to 15 minutes covered with foil.

To freeze: Let the baked oats cool completely, wrap them individually, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.

FAQs

Why use almond extract instead of vanilla? Almond extract gives birthday cake baked oats their signature funfetti flavor. Vanilla still works, but the final taste will be more like vanilla baked oatmeal than birthday cake batter.

How much protein is in birthday cake baked oats? This recipe contains 35 grams of protein per serving. The protein comes from the protein powder, egg, Greek yogurt icing, and oats.

Can I make birthday cake baked oats without protein powder? Yes, but the protein content will be much lower and the texture may change. Add 2 extra tablespoons of oats and use a full banana to help maintain the consistency.

Why are my baked oats dry? They may have baked too long, or your oven may run hot. Try reducing the baking time or lowering the temperature slightly.

Can I make this recipe in the microwave? Yes. Pour the blended batter into a wide microwave-safe bowl and cook in 1-minute intervals until set, usually 2 to 3 minutes total.
