- ¼ cup (25 g) unsweetened cocoa powder
- 1½ cups (180 g) powdered sugar
- ¾ cup (170 g) unsalted butter, melted (or coconut oil for dairy-free)
- 1 can (14 oz / 397 g) sweetened condensed milk

Instructions
- Step 1: Preheat your oven to 350°F (175°C) to ensure even baking.
- Step 2: In a large bowl, whisk together the graham cracker crumbs, cocoa powder, and powdered sugar until well combined and smooth.
- Step 3: Pour in the melted butter and sweetened condensed milk. Stir until the mixture is thick and sticky, ensuring all ingredients are fully blended.
- Step 4: Gently fold in the mini marshmallows, chocolate chips, and chopped nuts if using, taking care not to overmix to keep the marshmallows fluffy.

- Step 6: Remove from oven and let the bars cool completely before cutting into squares. Serve and enjoy!

FAQs
Can I use regular marshmallows instead of mini marshmallows?
Yes, regular marshmallows work fine, but mini marshmallows distribute more evenly throughout the bars for a consistent texture.
