Ingredients

Here is everything you need to make one serving. You can easily double or triple this recipe for meal prep.

• 1/2 cup old-fashioned rolled oats (do not use instant oats, they get too mushy)
• 1/2 cup milk (any milk works, including oat milk, almond milk, or whole milk)
• 1/4 cup plain Greek yogurt (adds creaminess and protein; regular yogurt works too but will be thinner)
• 2 tablespoons peanut butter (creamy or crunchy both work; almond butter is a great substitute)
• 1 tablespoon honey or maple syrup (adjust to your sweetness preference)
• 1/2 teaspoon vanilla extract
• 1 tablespoon cocoa powder or chocolate protein powder (optional, but adds a chocolate boost)
• 1/4 cup Reeses Pieces candy (mini Reeses cups work great too; use dairy-free chocolate for a vegan option)
• A pinch of salt (brings out all the flavors)

How to Make Reeses Pieces Overnight Oats

Follow these simple steps and you will have a delicious breakfast ready by morning. This whole process takes under five minutes.

1. Grab a jar or container. A mason jar works perfectly, but any airtight container with a lid will do the job.
2. Add the wet ingredients. Pour in the milk and Greek yogurt. Stir them together until combined.
3. Add the peanut butter and sweetener. Spoon in the peanut butter, honey or maple syrup, vanilla extract, and salt. Stir well until the peanut butter is fully mixed in.
4. Add the oats. Pour in the rolled oats and stir everything together. If you are using cocoa powder or protein powder, add it now and mix well.
5. Seal and refrigerate. Put the lid on your jar and place it in the refrigerator. Let it sit for at least 6 hours, but overnight (8 hours) gives the best texture.
6. Add the Reeses Pieces in the morning. This is the most important tip. Do not add the candy the night before or it will get soggy. Stir your oats in the morning, then top with Reeses Pieces right before eating.
7. Enjoy! You can eat it cold straight from the fridge or let it sit on the counter for a few minutes if you prefer it less cold.

Pro Tips for Perfect Reeses Pieces Overnight Oats

These little tricks will take your oats from good to absolutely amazing. Keep these in mind every time you make this recipe.

• Always use rolled oats. Quick oats and instant oats break down too much overnight and turn into mush. Old-fashioned rolled oats keep a satisfying chewy texture.
• Add candy just before eating. Reeses Pieces will dissolve and lose their crunch if they sit in liquid all night. Always add them fresh in the morning.
• Stir before adding toppings. Give your oats a good stir in the morning. If they look too thick, splash in a little extra milk and stir until you reach your preferred consistency.
• Warm peanut butter slightly. If your peanut butter is hard or cold, microwave it for 10 seconds before adding it. It will mix in much more smoothly.
• Layer for a beautiful presentation. If you are making this to share or post on social media, layer the oat mixture and toppings in a clear glass jar for a gorgeous look.
• Use a wide-mouth mason jar. It makes stirring and eating so much easier than a narrow jar.

Flavor Variations

Once you master the base recipe, try these fun twists to keep things exciting all week long.

• Double Chocolate Reeses: Add 2 tablespoons of chocolate protein powder or cocoa powder to the base. Drizzle with melted chocolate on top for an extra indulgent treat.
• Banana Peanut Butter: Mash half a ripe banana into the oat mixture before refrigerating. Top with Reeses Pieces and a few banana slices in the morning.
• Strawberry Reeses: Add a tablespoon of strawberry jam or fresh sliced strawberries in the morning alongside the Reeses Pieces for a fun fruity combo.
• Peanut Butter Cup Version: Swap Reeses Pieces for chopped mini Reeses Peanut Butter Cups. The flavor is very similar but the chocolate to peanut butter ratio changes slightly.
• Protein-Packed: Add a scoop of peanut butter or chocolate protein powder to the oat base. This is great for post-workout mornings when you need extra fuel.
• Nut-Free Version: Use sunflower seed butter instead of peanut butter. Look for a nut-free candy topping or use dairy-free chocolate chips in place of Reeses Pieces.

Storage Tips

Proper storage keeps your oats fresh and tasty all week. Here is everything you need to know.

• Refrigerator: Store prepared overnight oats (without the Reeses Pieces topping) in an airtight container in the fridge for up to 5 days.
• Toppings separate: Keep your Reeses Pieces in a small bag or container separate from the oats. Add them right before eating to preserve their crunch.
• Do not freeze: Overnight oats do not freeze and thaw well. The texture becomes grainy and watery after freezing, so stick to refrigerator storage.
• Meal prep batch: You can make up to 5 jars at once on Sunday night. Line them up in the fridge and breakfast is handled for the whole work week.

Frequently Asked Questions

Can I eat reeses pieces overnight oats warm?

Yes, you can absolutely enjoy your reeses pieces overnight oats warm. Simply remove the lid and microwave for 60 to 90 seconds, stirring halfway through. Wait to add the Reeses Pieces until after you heat the oats so the candy does not fully melt.

How long do overnight oats last in the fridge?

Overnight oats last up to 5 days in the refrigerator when stored in a sealed airtight container. For best results, keep any candy or crunchy toppings separate and add them right before eating. The oat base itself stays fresh and creamy for the full five days.

Can I use quick oats instead of rolled oats?

You can use quick oats in a pinch, but the texture will be much softer and mushier compared to old-fashioned rolled oats. Rolled oats hold their shape overnight and give you a satisfying chew. If mushy oats do not bother you, quick oats will still work fine.

Are reeses pieces overnight oats healthy?

Reeses pieces overnight oats can absolutely be part of a healthy, balanced diet. The base of oats, Greek yogurt, and peanut butter provides protein, fiber, and healthy fats that fuel your morning. The Reeses Pieces add some extra sugar, but you can use a smaller amount or swap for a lower-sugar candy alternative if you prefer.

Can I make this recipe dairy-free or vegan?

Yes, this recipe is easy to make dairy-free and vegan with a few simple swaps. Use oat milk or almond milk instead of regular milk, swap Greek yogurt for a dairy-free coconut yogurt, and replace honey with maple syrup. For the topping, look for vegan chocolate candies or use dairy-free chocolate chips instead of Reeses Pieces.

These reeses pieces overnight oats are honestly one of the most fun and satisfying breakfasts you can make. They bring together the nostalgic flavors of peanut butter candy with the wholesome goodness of oats, yogurt, and real ingredients.
