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.
