Why You’ll Love This Oreo Overnight Oats Recipe

This recipe is a game-changer for busy mornings. It requires zero cooking, is completely customizable, and combines the childhood nostalgia of Oreos with the nutrition of oats. You get the creamy texture of soaked oats, the crunch of cookie crumbles, and a balanced sweetness that makes it feel like a treat. Plus, it’s great for meal prep!

What Kind of Oats Should I Use?

For overnight oats, old-fashioned rolled oats work best. They absorb the liquid well, becoming soft and creamy without turning mushy. Quick oats tend to break down too much overnight, while steel-cut oats won’t soften enough. Stick to rolled oats for the perfect texture.

Options for Substitutions

• Milk: Use any milk you like—dairy, almond, oat, soy, or coconut. Each gives a slightly different flavor profile.
• Yogurt: For extra creaminess, add a scoop of Greek yogurt or any plant-based alternative.
• Sweetener: Honey, maple syrup, agave, or even a mashed banana can be used to adjust sweetness to your liking.
• Oreos: Any sandwich cookie works! Try golden Oreos, gluten-free varieties, or even chocolate mint for a twist.
• Protein Boost: Add a scoop of vanilla protein powder or chia seeds to turn it into a high-protein breakfast.

Ingredients for This Oreo Overnight Oats Recipe

• Old-Fashioned Rolled Oats: These are the backbone of the recipe. They soak up the liquid and soften overnight without losing their texture.
• Milk of Choice: This adds moisture and creaminess. Whether you prefer dairy or plant-based, it ties everything together.
• Greek Yogurt (optional but recommended): Provides added protein and a creamy, tangy contrast to the sweet Oreos.
• Chia Seeds: Help thicken the oats naturally and offer fiber, omega-3s, and a slight crunch.
• Maple Syrup or Sweetener: Balances the cocoa bitterness from the Oreos and adds depth to the flavor.
• Vanilla Extract: Enhances the cookie-and-cream flavor profile subtly but effectively.
• Crushed Oreos: The star of the recipe—adds sweetness, texture, and that classic cookies & cream taste.
• A Pinch of Salt: Amplifies all the flavors, making them more pronounced and well-rounded.

Step 1: Prepare the Base Mixture

In a mason jar or any airtight container, add 1/2 cup of rolled oats, 1 tablespoon of chia seeds, and a pinch of salt. These dry ingredients are the foundation of your oats.

Step 2: Add the Creamy Elements

Pour in 1/2 cup of your preferred milk and 1/4 cup of Greek yogurt. Stir to ensure all the dry ingredients are moistened and well incorporated.

Step 3: Sweeten and Flavor

Add 1 teaspoon of maple syrup (or adjust to taste) and 1/2 teaspoon of vanilla extract. Mix again until everything is evenly blended.

Step 4: Fold in the Oreos

Crush 2–3 Oreo cookies and gently fold them into the mixture. You can leave some bigger chunks for texture or crush them finely for a more blended flavor.

Step 5: Chill Overnight

Seal the container and place it in the fridge for at least 4 hours, preferably overnight. This allows the oats and chia seeds to soak and thicken.

Step 6: Serve and Garnish

The next morning, give the oats a good stir. If the mixture is too thick, add a splash of milk. Top with extra crushed Oreos or a whole cookie for visual appeal and added crunch.

How Long to Prepare the Oreo Overnight Oats Recipe

Active Time: The hands-on time for preparing Oreo Overnight Oats is about 5 to 7 minutes. That includes measuring, mixing, and crushing Oreos—quick and simple enough to do even on a busy evening.

Chilling Time: For the best texture, let it chill in the fridge for at least 4 hours, though overnight (8 hours) is ideal. This gives the oats and chia seeds time to fully absorb the liquid and soften to a creamy consistency.

Tips for Perfect Oreo Overnight Oats

• Use rolled oats for the best texture; they hold up overnight without becoming mushy.
• Crush Oreos coarsely if you want texture, or finely for a uniform creamy flavor.
• Adjust the sweetness to your preference—Oreos are sweet, so you might not need much maple syrup.
• Stir thoroughly before refrigerating to evenly distribute the chia seeds and Oreo bits.
• Add a splash of milk in the morning if it’s too thick after chilling.

Watch Out for These Mistakes While Cooking

• Using instant oats: They turn mushy and don’t hold up well overnight.
• Adding too many Oreos: While tempting, too many can make the oats overly sweet and soggy.
• Forgetting to stir: Ingredients may clump or settle unevenly, especially chia seeds.
• Skipping the salt: Just a pinch enhances flavor and makes everything taste more balanced.
• Not sealing the container: This can dry out the oats or cause off flavors in the fridge.

3. Peanut Butter Drizzle

Storage Instructions

Refrigeration: Store your Oreo Overnight Oats in an airtight container in the fridge for up to 3–4 days. The texture will remain creamy, though the Oreos may soften more over time.

Meal Prep Friendly: You can make multiple jars at once for the week. Just layer the ingredients or mix in one bowl and portion them into containers.

Avoid Freezing: Freezing is not recommended. The texture of the oats and Oreos changes too much once thawed, resulting in a mushy and less enjoyable consistency.
