Indulge in these luscious chocolate hazelnut overnight oats that capture the essence of Ferrero Rocher. Creamy Greek yogurt and protein powder create a rich, satisfying base, while roasted hazelnuts and dark chocolate add that signature crunch. Simply mix the night before and wake up to a luxurious, protein-packed breakfast that feels decadent yet fuels your morning with wholesome ingredients.
My roommate walked into the kitchen at midnight while I was aggressively stirring cocoa powder into yogurt, looking mildly concerned. She asked if I was having a chocolate crisis, and I explained that I just really wanted dessert for breakfast but needed it to pass as healthy. After three attempts that either tasted like chalky protein shakes or sad chocolate pudding, this version finally clicked.
I made these for a hiking trip last summer and my friends accused me of withholding dessert until morning. They were genuinely confused when I explained it was just oats with protein powder and hazelnut butter. Now it is requested for every group breakfast, even the ones where we are not waking up at dawn to climb mountains.
Ingredients
- 1 cup rolled oats: Use old-fashioned oats for the best texture, instant oats turn into mush
- 1 cup unsweetened almond milk: Any milk works but almond keeps it light and lets the chocolate shine through
- 1/2 cup plain Greek yogurt: This is what makes it taste like dessert, trust me on this one
- 2 tbsp chocolate protein powder: I use a chocolate whey but any chocolate protein works
- 1 tbsp unsweetened cocoa powder: Do not skip this, it is what gives it that deep chocolate flavor
- 2 tbsp hazelnut butter: The secret ingredient that makes it taste like a Ferrero Rocher
- 1 tbsp maple syrup or honey: Adjust based on how sweet you like your breakfast
- 1/2 tsp vanilla extract: Pure vanilla makes all the difference here
- Pinch of salt: Just a tiny pinch brings out all the chocolate flavors
Instructions
- Make the chocolate hazelnut base:
- Dump everything into a bowl and mix it really well, making sure to break up any clumps of cocoa powder or protein powder. It should look like chocolate pudding but slightly thicker.
- Divide into jars:
- Scoop the mixture into two containers, leaving some room at the top for toppings tomorrow.
- Let it work its magic:
- Pop those jars in the fridge for at least 4 hours but overnight is better. The oats need time to soften and all the flavors need time to become best friends.
- Add the fancy toppings:
- Right before you eat, give it a good stir and pile on the chopped hazelnuts and dark chocolate pieces.
- Go wild with the garnish:
- Drizzle extra hazelnut butter on top and maybe half a Ferrero Rocher if you are feeling extra indulgent today.
My sister now keeps a batch in her fridge at all times and says it has saved her from buying overpriced café breakfasts more times than she can count. She texts me photos of her morning jars like she is showing off a new pet.
Making It Vegan
Swap the Greek yogurt for coconut yogurt or a plant-based alternative, and make sure your protein powder is vegan friendly. The texture stays just as creamy and nobody will notice the difference.
Nut Butter Swaps
Hazelnut butter is ideal but I have used almond butter in a pinch and it still tastes like a chocolate almond joy. Peanut butter works too if you want it to taste more like a Reese cup situation.
Texture Hacks
For extra crunch, try adding crushed waffle cones or cacao nibs to the topping mix. My friend adds a teaspoon of chia seeds to the base for those little tapioca-like pearls.
- If it is too thick in the morning, splash in a little more milk
- Make a double batch and you are set for half the week
- These keep for up to 3 days in the fridge
Wake up tomorrow morning knowing you have dessert waiting for you in the fridge. Breakfast this good should not feel this healthy.
Recipe Questions & Answers
- → How long do these oats stay fresh?
-
These overnight oats stay fresh in the refrigerator for up to 3-4 days when stored in airtight containers. The flavors actually develop and intensify over time, making them perfect for meal prep.
- → Can I use different protein powder flavors?
-
Absolutely! While chocolate or chocolate hazelnut protein powder works best to complement the cocoa, vanilla protein powder also tastes delicious. Adjust the cocoa quantity slightly if using unflavored varieties.
- → What milk alternatives work best?
-
Unsweetened almond milk provides a neutral base that lets the chocolate hazelnut flavors shine. However, oat milk, cashew milk, or regular dairy milk all work wonderfully. Choose based on your preference and dietary needs.
- → How can I increase the protein content?
-
Bump up the protein by adding an extra tablespoon of protein powder, stirring in Greek yogurt, or incorporating a scoop of collagen peptides. Chia seeds also add a slight protein boost along with omega-3s.
- → Can I make these nut-free?
-
For a nut-free version, substitute hazelnut butter with sunflower seed butter and omit the hazelnuts. Add extra crushed dark chocolate or cacao nibs to maintain the crunch and chocolate intensity.
