As a busy baby momma, mornings can feel like a chaotic blur— breakfast needs to be quick, delicious, and fuss-free. Enter chocolate peanut butter overnight oats (aka peanut butter cup overnight oats). With just 10 minutes of prep (no cooking!), I can make a week’s worth of meal-prep breakfasts- it’s creamy, rich, protein-packed, and a Reese Cup lover’s breakfast dream (along with peanut butter granola cups!) while boosting energy and keeping me feeling fueled and satisfied until lunch!

You might enjoy my easy, wholesome, and satisfying healthy chocolate oatmeal bars, banana baked oatmeal, or homemade granola bars.

The Ingredients and Substitutes

The Banana Overnight Oats

• Rolled oats: Old-fashioned oats/rolled oats are best. Use certified gluten-free oats if necessary.
• Chia seeds: Overnight oats with chia seeds are heartier, thicker, and have added protein, fiber, and omega-3s. Omit if preferred.
• Mashed banana: Use an overripe banana with plenty of black spots for natural sweetness.
• Plant-based milk: Use your favorite dairy-free milk (almond milk, soy, cashew, coconut, rice, etc.). For a lighter option, use water, but it won’t be as creamy or flavorful. For creamier chocolate PB overnight oats, use 50/50 milk and vegan Greek yogurt.

Healthy Peanut Butter Chocolate Ganache

• Peanut butter: I use creamy peanut butter without added oils or sugar. If preferred, use other seed/ nut butter like almond butter, hazelnut, cashew, or sunflower seed butter.
• Coconut milk: Use full-fat canned coconut milk for the creamiest results.
• Chocolate: Use semisweet/bittersweet chocolate or even sugar-free/keto chocolate.
• Vanilla extract: Natural, pure vanilla will have the best flavor.
• Salt: Just a pinch enhances the flavors in the chocolate peanut butter overnight oats.
• Sweetener: (optional) Add a few drops of stevia or liquid sweetener (maple syrup, agave, brown rice syrup, date syrup, etc.).

Recipe Variations

• Cocoa powder: Add 1 tbsp unsweetened cocoa powder to the oats for an extra chocolatey twist.
• Protein powder: Add ½ a scoop of your favorite unflavored, vanilla, banana, chocolate, or peanut butter flavored protein powder. Add extra milk as needed.
• Cinnamon: Just a pinch for warm depth.
• Coconut: Add 1 tbsp unsweetened shredded coconut to the oats for texture.
• Toppings: Chocolate banana peanut butter overnight oats pair with several things, like
  • Fresh fruits/berries (strawberries, raspberries, blueberries, sliced banana, etc.)
  • Chopped peanuts
  • Flaky sea salt
  • Cacao nibs/ chocolate chips
  • A drizzle of peanut butter

How to Make Chocolate Peanut Butter Overnight Oats

• First, mash the banana in a medium bowl with a fork (or small food processor/bender).
• Transfer the banana to a mason jar (or drinking glass) and stir in the chia seeds, oats, and plant-based milk. Transfer it to the fridge.

• To prepare the topping, add the peanut butter, coconut milk, and dairy-free chocolate to a small heat-proof bowl. Microwave for 30 seconds OR use a double-boiler to melt the ingredients, stirring well to combine.
• Stir in the vanilla and salt.
• Pour the ganache over the chia oat mixture and chill the chocolate PB overnight oats for at least 2 hours or overnight. Optionally add toppings and enjoy!

Storage Instructions

Freeze: You can freeze base overnight oats in an airtight container for up to 3 months. Thaw in the refrigerator overnight before adding toppings and serving.

FAQs

Can I eat overnight oats warm?

Overnight oats are best enjoyed chilled. However, you could microwave them (for 40-80 seconds) if you’d prefer.

Can I use quick oats?

Quick oats work perfectly, I used them myself for this recipe!

Could I use steel-cut oats?

I don’t recommend them, as they remain harder and chewier than rolled oats even after 10 hours of soaking.

Are overnight oats healthy?

Yes, overnight oats are healthy! My base recipe combines oats, chia seeds, and (sugar-free) peanut butter—a nutrient-rich mix full of fiber, plant-based protein, vitamins, and minerals. For an even healthier version, you can use sugar-free chocolate!

Top Recipe Tips

1. For firmer overnight oats: Omit or use less chia seeds, soak the overnight oats for less time (2-3 hours should do it) OR use a little less liquid.
2. If it’s too thick: Add an extra splash of milk/water before serving.
3. Sweeten to taste: If the bananas’ sweetness isn’t enough, add liquid sweetener to taste.
4. For more peanut butter flavor: Add a tablespoon of peanut butter (or peanut butter powder) to the banana overnight oats.
5. Optimal soak time: I recommend 2 hours minimum, but overnight oats are best after 7-8 hours.
