Are Oats Healthy?
First things first, are overnight oats healthy? Yes, absolutely. Oats are packed with nutrients, especially fiber, making them a nourishing and satisfying choice for breakfast. Thanks to their complex carbs, they provide long-lasting energy and are easy to customize with toppings that boost your nutrient intake even more. When you pair them with healthy fats and some protein, you’ve got a balanced breakfast that helps keep you full and satisfied for hours.
Oats are also rich in beta-glucans, a type of soluble fiber that supports gut health and can help lower cholesterol levels. Regular consumption of whole grains, including oats, is linked to a lower risk of chronic disease and a reduced risk of early death.
They’re also one of the few grains that contain avenanthramides, antioxidants that may help reduce blood pressure and have anti-inflammatory effects. Oats are budget-friendly, easy to prep ahead, and perfect to keep in the fridge for busy mornings.

Ingredient Notes
- Medjool Dates: A natural sweetener rich in fiber.
- Peanut Butter: Adds creaminess, healthy fats, and protein. Almond butter can be a great alternative.
- Dark Chocolate: A source of antioxidants and magnesium. Choose some high-quality dairy-free chocolate chips for the best flavor. If you cannot get dark chocolate chips, use a regular dark chocolate block, chopped up into small pieces, to help it melt quicker.
- Soy Milk: Rich in protein; try to choose a fortified calcium option. Any non-dairy milk, such as almond milk, can be used in its place, but it will lower the protein content.
- Chia Seeds: Loaded with nutrients, including omega-3s, they help thicken the oats.
- Protein Powder: Get a good quality plant-based protein powder (we ideally want to look for a powder with two different plant sources of protein to optimize the amino acid profile, a minimum of 20 g of protein per serving, and 2 g of leucine per serving)
Step-By-Step Instructions
Combine the oats, chia seeds, vanilla protein powder, and 1.5 cups of soy milk in two jars (or a meal prep container). Stir well and let it sit in the fridge for at least 4 hours (or overnight).

Blend the Medjool dates, peanut butter, and 1/4 cup of soy milk to create the peanut date caramel and spread across the top of the oats.

Melt the chocolate by heating it in the microwave at 20-second intervals, stirring each time. Top with chopped peanuts and a sprinkle of sea salt. Let it sit in the fridge for another 30 minutes to let it set before enjoying. View the full recipe below for all the details.

Variations and Tips
- For a fruity twist, try topping with fresh raspberries.
- Make it a nut-free version: swap peanuts and peanut butter with seeds and tahini.
- Skip the protein powder: add extra chia seeds and a bit of vanilla extract instead.
- No blender? No worries, swap the dates for a bit of maple syrup and whisk it all together with peanut butter and milk.
- Chocolate version: Add some cocoa powder to the oat mix, or swap the vanilla protein powder for a chocolate protein powder.
