Easy Oreo Overnight Oats

Oreos for breakfast? Yes, please! If you're a die-hard Oreo fan like me, you will love this overnight oats recipe!

Oreo overnight oats taste like a smooth, chocolatey dessert that's disguised as breakfast. You have the sweet flavor of crushed Oreo cookies blended into smooth oats and milk, with a hint of vanilla. It's like having the best flavors of cookies and cream but in a hearty way.

If you're looking for a new breakfast meal, you should try these cookies and cream overnight oats. It’s a great option for those busy mornings when you’re craving something sweet but still want to keep the sugar in check.

What you need to make this recipe

Ingredients for Oreo overnight oats

• Oats: I always use old fashioned rolled oats. They provide a creamy texture that holds up overnight.
• Milk: I love using unsweetened almond milk, but you can add your favorite milk. Regular, dairy milk creates a rich and creamy base, but plant-based milk works fine, too.
• Oreo cookies: Of course, these are the star ingredients!
• Vanilla extract: I use pure vanilla extract for a touch of sweetness and added flavor.
• Honey: It adds natural sweetness, but you could also use maple syrup, instead.
• Pinch of salt: It really enhances all the other flavors and adds balance.

How to make Oreo Overnight Oats

Step-by-step Instructions

1. Add all the ingredients to a mason jar.

2. Stir until well combined.

Then seal the jar (or container) and refrigerate overnight. The next morning, give the oats a stir and top with your favorite toppings, like additional crushed Oreos.

Storage Tips & Freezing Instructions

• Refrigeration: Store overnight oats in an airtight container in the refrigerator for up to 4 days.
• Freezing: After the oats have been in the refrigerator overnight, you can portion them into freezer-safe containers and freeze for up to 3 months. Thaw in the refrigerator overnight before eating.

Variations 

• Gluten free: To make this recipe gluten free, use gluten free old fashioned rolled oats and Oreo cookies.
• Make Vegan Oreo Overnight Oats: Just use plant-based milk and replace the honey with maple syrup.
• Protein Overnight Oats: Add a scoop of vanilla or chocolate protein powder for extra protein.
• Peanut Butter Oreo Oats: Stir in a tablespoon of peanut butter for added richness and a nutty flavor.
• Tiramisu Overnight Oats: Coffee is amazing with these oats. Just add a splash of coffee and a dusting of unsweetened cocoa powder for a tiramisu-inspired flavor.
• Easy Overnight Oats with Yogurt: Add plain Greek yogurt instead of milk for a tangier flavor. I love Fage 2%.
• Berry Oreo Oats: Mix in fresh or frozen berries for a fruity contrast. I like strawberries and blueberries with these oats.
• Biscoff Overnight Oats: Add about 2 tablespoons Biscoff cookie butter to the filling. Then top with some more melted Biscoff spread and crushed Biscoff cookies.
