Ingredient Notes
- Graham cracker crumbs – You can buy them pre-crushed or pulse whole graham crackers in a food processor.
- Sweetened condensed milk – This is the secret to the gooey magic; don’t substitute with evaporated milk.
- Milk chocolate chips – Feel free to swap in semi-sweet or a chopped chocolate bar if you prefer.
- Mini marshmallows – These melt perfectly and give that classic s’mores goo factor.
- Birthday Cake Golden Oreos – Adds a funfetti flavor and a bit of crunch. Crushing them by hand gives a great texture mix.
- Rainbow sprinkles – Jimmies or confetti-style work best so they don’t melt too much in the oven.
Before You Bake
Do I need to crush the Oreos completely?
Nope! A rough chop works best—keep some bigger chunks for crunch and texture in every bite.
Can I use regular Golden Oreos instead of Birthday Cake?
Yes, but the Birthday Cake version adds extra flavor and fun. If you’re using plain, consider adding a touch of vanilla extract or extra sprinkles.
Will the bars set up enough to slice cleanly?
Yes, as long as you let them cool completely. For extra clean cuts, chill them for 20–30 minutes before slicing.

FAQ
Can I double the recipe?
Absolutely. Just use a 9×13-inch pan and extend the bake time by about 5 minutes.
Do Sprinkle S’mores Bars need to be refrigerated?
They can be stored at room temperature for up to 4 days, but refrigerating helps them stay firm and chewy longer.
Can I make these gluten-free?
Yes! Use gluten-free graham cracker crumbs and Oreos. Everything else should be naturally gluten-free—just double-check your labels.
How do I store leftovers?
Keep in an airtight container at room temp or in the fridge. They also freeze well—wrap individually and store for up to 2 months.
