Ingredient Notes

You’ll find the full ingredient list in the recipe card below. These notes will help you get the best flavor, texture, and consistency.

• Rolled oats (also called old-fashioned oats) are the best oats to use for overnight oats. Instant oats turn mushy, and steel-cut oats won’t soften enough without cooking.
• Cacao powder and cacao nibs give these oats a deep chocolate flavor while providing fiber, iron, flavonoids, and other nutrients. If you don’t have cacao powder, unsweetened cocoa powder works just fine.
• Chia seeds are my favorite superfood to add to overnight oats. They help create a creamy texture and add fiber, protein, and omega-3s.
• Unsweetened almond milk is what I most often use, but coconut milk or any non-dairy milk works well. You can also use dairy milk if that’s what you have.
• Natural Peanut butter adds richness, flavor, healthy fat, and protein. I recommend using natural peanut butter with peanuts as the only ingredient to avoid added oils and sweeteners.
• Pure maple syrup adds just enough sweetness to balance the chocolate. I like starting with less and adjusting in the morning.

Supplies

You can use any container with a lid, but my go-to is a 16-ounce wide-mouth mason jar. It’s perfect for portion control, easy to transport, and makes overnight oats truly grab-and-go. Plastic mason jar lids are especially convenient for everyday use.

How to Make Chocolate Peanut Butter Overnight Oats {Step-by-Step}

• Step 1: Mix the dry ingredients. Add the rolled oats, cacao powder, and chia seeds to a 16-ounce mason jar. Stir until evenly combined.
• Step 2: Add the wet ingredients. Add the peanut butter, almond milk, vanilla extract, and maple syrup. Stir until everything is well mixed and chocolatey.
• Step 3: Refrigerate overnight. Cover tightly with a lid and refrigerate for 6–8 hours or overnight.
• Step 4: Adjust and enjoy. Remove the lid and give the oats a good stir. Stir in the maple syrup. If the oats are too thick, stir in a splash of milk until creamy.
• Step 5: Finish and serve. Sprinkle with cacao nibs and drizzle with extra peanut butter if desired. Enjoy straight from the jar or in a bowl.

Expert Tips & Variations

• To reduce fat and calories, swap the peanut butter for PB2 or powdered peanut butter. Use about 2 tablespoons of powdered peanut butter in place of regular peanut butter. You can also check out my overnight oats with PB2 recipe for inspiration.
• Peanut butter already adds protein, but if you want more, stir in a 2 tablespoons of Greek yogurt, 1/4 cup cottage cheese, collagen powder, protein powder, hemp hearts, or other high-protein superfoods. You may need to add a little extra milk if the oats seem dry.
• You can also switch up the nut butter and use almond butter, cashew butter, or sunflower butter for a different flavor.

Make-ahead tips

For weekly meal prep: Prepare jars on Sunday and store them in the refrigerator for up to 5 days.

For freezing: You can assemble the dry ingredients in jars or freezer bags and freeze for up to 3 months. When ready to use, add milk and refrigerate overnight. My overnight oats freezer kit tutorial walks through this process step by step.
