Chocolate Peppermint Protein Oat Bake
This chocolate peppermint protein oat bake tastes like peppermint hot chocolate—but healthy! High-protein, gluten-free, and perfect for meal prep all December long.
Creator: Leslie Stokes
If you’re anything like me, December hits and suddenly breakfast becomes whatever your kids didn’t finish… plus coffee. And then January shows up and we all swear we’re “totally getting back into routine.”
This oat bake is my little gift to that in-between season. It tastes like a peppermint hot chocolate, but it’s secretly packed with protein, gluten-free, and the easiest breakfast to grab all week. My kids think it’s a treat, I get 17g of protein before 9am — everybody wins.
You whisk everything in one bowl, bake it, slice it, and boom: breakfast for the next several days. And because it uses chocolate protein shake + cottage cheese, it stays soft and fluffy instead of dry like some baked oat recipes.
This is one of those meal prep recipes that makes you feel like you have your life together… even if the rest of December is chaos.
Make it for breakfast meal prep, make it for a healthy holiday treat, make it because peppermint season deserves its moment — it’s cozy, festive, and just feels fun.
Meal Prep + Storage Tips
To store (fridge):
Store slices in airtight containers for 4–5 days.
Drizzle with a little chocolate protein shake before reheating to keep it soft.
To freeze:
Wrap each square tightly in parchment + foil or place in a freezer-safe container.
Freeze for up to 3 months.
To reheat:
Microwave 20–30 seconds.
For a “fresh-baked” feel, air fry at 350°F for 2–3 minutes.
Meal prep add-ons:
Serve with Greek yogurt for an extra 10–15g protein.
Add crushed candy cane on top for a fun December breakfast moment.
