Mint Chocolate Overnight Oats (Thin Mint + Chocolate Shell)

These mint chocolate overnight oats taste like a Thin Mint cookie, made with chocolate protein powder and finished with a dark chocolate shell you crack with your spoon.

Mint chocolate overnight oats are oats soaked overnight with almond milk, chia seeds, cocoa powder, chocolate protein powder, and a few drops of peppermint extract. This version gets a layer of melted dark chocolate and coconut oil on top, then 10 minutes in the freezer so it sets into a crackable shell.

It’s the same freeze-and-crack shell as my Snickers Overnight Oats, just mint chocolate. Ready and waiting when you wake up, which is the whole point on a busy morning, and fun enough for Christmas morning too.

Ingredients for Mint Chocolate Overnight Oats

For the oats

• Certified gluten-free oats: quick or old-fashioned both work. Skip steel-cut, they stay chewy.
• Unsweetened almond milk: I like it because the flavor stays neutral, but cashew, coconut, oat, soy, or regular milk all work.
• Chia seeds: soak up the liquid so the oats set thick, plus healthy fats.
• Chocolate protein powder: I use PEScience Chocolate Mint Cookie (code BAILEY saves you money). It tastes like fresh mint chocolate, so it does half the flavor work. They have vegan options too.
• Unsweetened cocoa or cacao powder: for deep chocolate flavor.
• Pure peppermint extract: just a few drops. It’s strong, so don’t overdo it.

For the chocolate shell

• Dark chocolate chips and coconut oil: melted together and poured over the chilled oats. The coconut oil is what makes it set into a thin, snappy shell. Milk chocolate or a vegan brand works too.
• To finish: crushed Thin Mints or Oreo pieces and a fresh mint leaf.

Optional add-ins: maple syrup, flax or hemp seeds, cacao nibs, vanilla extract, a spoonful of plain Greek yogurt, or an extra scoop of protein.

How to Make Mint Chocolate Overnight Oats

1. Add the oats, almond milk, chia seeds, protein powder, cocoa powder, and peppermint extract to a jar or bowl and stir well.
2. Cover and refrigerate for at least 4 hours or overnight.
3. Microwave the chocolate chips and coconut oil until melted.
4. Pour the melted chocolate over the chilled oats and spread it to cover the top.
5. Sprinkle with crushed cookies.
6. Freeze for about 10 minutes, until the chocolate sets.
7. Crack it open with your spoon.

How to Store Mint Chocolate Overnight Oats

Keep leftovers in an airtight glass jar or container in the fridge for 3 to 4 days, and label it with the date you made it. A wide-mouth mason jar is the easiest for one serving. For batch prep, meal-prep containers work best, or use a bowl if you like to warm your oats up in the morning.
