Ingredients in birthday cake overnight oats

  • Oats: Rolled oats are the best for overnight oatmeal. They are perfect for soaking because they have been steamed and flattened. Do not use instant, quick, or steel cut oats.
  • Milk: Use your favorite type of milk. It can be non-dairy milk or regular milk. I suggest unsweetened vanilla almond milk or oat milk for the best flavor.
  • Vanilla yogurt: Although this ingredient is optional, it creates the best oatmeal consistency. Use non-dairy vanilla yogurt or regular yogurt.
  • Cashew butter: This is the best nut butter because it has a naturally sweet flavor. If you don’t have any, you can use almond butter instead.
  • Maple syrup: Add real maple syrup in order to keep the oats refined sugar-free. Honey and agave nectar also work well. If you don’t mind added sugar, regular cane sugar can be used.
  • Chia seeds: Chia seeds expand while soaking in milk, which creates a super creamy texture. Additionally, they are a good source of omega-3 fatty acids and fiber.
  • Vanilla extract: A dash of vanilla is required to create an authentic birthday cake flavor.
  • Almond extract: This extract is extremely sweet. It’s a secret ingredient for all funfetti recipes! Only a tiny dash is needed.
  • Sprinkles: Don’t forget rainbow sprinkles to create a funfetti appearance.
  • Salt: Add a pinch of salt to balance the sweet ingredients.

Frequently asked questions (FAQ)

Are overnight oats good for weight loss?

Yes, they can be. This recipe contains 7 grams of fiber and 10 grams of protein per serving. Therefore, it may keep you full and satisfied for hours. Additionally, since oats are a slow-digesting carbohydrate, it’s often a better choice than fast-digesting carbs (like toast or cereal).

Is overnight oats a healthy snack?

Definitely! Given the recipe’s ingredients are healthy, you can consider this a nutritious snack idea.

Why can’t you use water with oats overnight?

No, 24 hours is perfectly fine. Personally, I recommend enjoying the oatmeal within 24 hours. However, you can meal prep these oats and let them sit for 2-3 days.

Is overnight oats healthier than oatmeal?

Typically, they are equally healthy. The answer depends on the recipe’s ingredients.
