How to Make Sugar Cookie Overnight Oats

Making overnight oats couldn’t be easier! Here’s how to prepare them in just a few simple steps.

Step 1: Combine the Ingredients

Add the rolled oats, milk, vanilla protein powder, vanilla extract, almond extract, maple syrup, and salt to a mason jar or airtight container.

Step 2: Mix Everything Together

Stir thoroughly until the protein powder is completely incorporated and all the oats are coated in the liquid. If the mixture seems too thick, add a small splash of milk.

Step 3: Refrigerate Overnight

Place the lid on the jar and refrigerate overnight, or for at least 4 hours, to allow the oats to soften and absorb the liquid.

Step 4: Add Your Favorite Toppings

When you’re ready to eat, give the oats a good stir. Top with vanilla Greek yogurt and sprinkles for the ultimate sugar cookie flavor.

Step 5: Enjoy!

Enjoy your sugar cookie overnight oats straight from the jar for a quick and delicious breakfast!

Tips for the Best Overnight Oats

Use old-fashioned rolled oats. Rolled oats create the best creamy texture. Quick oats can become overly soft, while steel-cut oats generally need a different preparation method.

Don’t skip the almond extract. This is what really gives these overnight oats their sugar cookie flavor! A little goes a long way, so feel free to adjust it to your preference.

Choose a protein powder you enjoy. Since protein powder contributes a lot of flavor, use a vanilla protein powder you already like. Different brands absorb liquid differently, so you may need to adjust the amount of milk.

Add Greek yogurt for extra creaminess. Vanilla Greek yogurt makes these oats taste even more like dessert while adding protein.

Save the sprinkles for serving. If you want the sprinkles to stay colorful and prevent their colors from bleeding into the oats, add them right before eating.

How to Meal Prep Overnight Oats for the Week

One of my favorite things about this recipe is how easy it makes breakfast during a busy week!

Simply prepare several jars at once, adding the ingredients to each jar and stirring until combined. Seal the jars and store them in the refrigerator.

For the best freshness and texture, enjoy refrigerated overnight oats within 4–5 days. Make sure to keep them properly chilled in airtight containers.

I love using individual overnight oats jars because they’re easy to grab in the morning and make portioning breakfast so simple.
