My daughter is a huge fan of chocolate and peppermint. Her favorite ice cream? Mint chocolate chip. Her favorite Girl Scout cookie? Thin Mints. So when she asked me a while back to make her Chocolate Peppermint Overnight Oats, I knew we’d have a hit on our hands. And boy, did we ever!

My girl has been a fan of Mama’s overnight oats since soon after she started eating solids (Chocolate Peanut Butter Overnight Oats was her original favorite flavor), but this Chocolate Peppermint version takes her love of overnight oatmeal to the next level! She requests it every single time I head to the kitchen to meal prep.

I love it because it’s stupendously easy to make, and it’s an easy grab-and-go healthy breakfast for hectic school day mornings. The oats fill her up so she has plenty of energy for school, and I don’t have to lift a finger in the morning. It’s a parenting win!

While all of our overnight oats recipes are amazing, the chocolate ones really are magic because of a chemical reaction between the cocoa powder and the acid in the yogurt that makes them supremely fluffy and creamy. It’s a must-try for any chocolate-lover! It happens with these oats, but also our Chocolate Peanut Butter, Chocolate Coconut, and Mocha Overnight Oats—try them all!

What are overnight oats?

Overnight oats are a no-cook oatmeal that you stir together and let rest overnight in the fridge. In the morning, you have a dreamy pudding-like porridge that you can eat cold (my preferred method), or warm up.

Do you eat overnight oats cold or heated up?

Most folks choose to keep overnight oats as a grab-and-go breakfast, and eat them cold (and hello, it’s like eating pudding for breakfast!). But if you’d rather have them hot, just heat them in a small saucepan on the stove, or warm them in the microwave for 30-60 seconds, stirring frequently.

  1. Mint chocolate chip is one of my favorite flavors but mint can be tricky and overbearing so I hesitated for a long time before trying it in overnight oats form. But your recipe nailed the ratio! It was so good and I can’t wait to have it again!
