Variations

- Swap Reeseโs Pieces for mini chocolate chips or candy corn for different fall colors
- Add chopped pecans or walnuts for crunch
- Use almond butter instead of peanut butter
- Mix in dried cranberries for tartness
- Make it fully Halloween themed by using orange and black candies instead of Reeseโs Pieces
Leftovers & Storage
Store your fall puppy chow in an airtight container at room temperature for up to 1 week. The key is making sure theyโre completely set before storing so they donโt get sticky. You can also divide them into smaller containers or bags for easy grab and go snacks throughout the week.
Tips & Tricks
- Donโt skip stirring between microwave intervals or your chocolate mixture might get lumpy.
- Make sure to coat every piece of cereal well with the chocolate mixture before adding to the bags.
- Shake the bags really well to get an even coating of powdered sugar on everything.
- Let the muddy buddies set for a full hour so the coating hardens properly and doesnโt get sticky.
- Add the Reeseโs Pieces right before serving.
- If you donโt have two large bags, you can do this in batches with smaller bags.

Recipe FAQs
Can I make this without peanut butter?
Yes! You can substitute with almond butter, sunflower seed butter, or just use extra butter and increase the white chocolate chips slightly for richness.
What if I donโt have pumpkin pie spice?
You can make your own by mixing together cinnamon, nutmeg, ginger, and a pinch of cloves, or just use cinnamon for a simpler version.
Can I use milk chocolate instead of white chocolate?
Absolutely! Milk chocolate or even semi sweet chocolate chips work great, though the flavor will be a bit different from the classic white chocolate base.
How do I know when the mixture is properly melted? It should be smooth and completely combined with no lumps of chocolate or peanut butter. If it looks grainy, keep microwaving in 10 second intervals.
Can I make this ahead of time?
Yes! Puppy chow keeps really well for several days and is perfect for making ahead for parties or gatherings. Itโs great for holiday parties!
What if my coating looks clumpy?
Make sure your chocolate mixture has cooled slightly before coating the cereal and donโt be afraid to break up any clumps with your hands before adding the Reeseโs pieces.
