First, let’s preheat that charming oven of yours to a cozy 350 degrees Fahrenheit. Don’t forget to lightly spray a 9 x 13 glass baking dish with non-stick cooking spray to ensure our brownies don’t stick! Now, on to the crust—take your crushed graham crackers and combine them in a bowl with melted butter and half a cup of sugar. Mix them together with your hands or a fork, then press it evenly into the bottom of your baking dish. Set this delightful crust aside!

Next up, let’s make the brownies! In a large bowl, cream together the softened butter and sugar until the mixture is light and fluffy, almost like a cloud! In a separate bowl, whisk together the flour, baking powder, and cocoa. Gradually add this dry mixture to the buttery goodness, stirring well with an electric mixer.

Don’t forget to stir in the milk and vanilla, giving it that lovely flavor. Next, add the eggs one by one, ensuring to mix well after each addition. Now comes the fun part—fold in those little mini peanut butter cups! Pour this beautiful brownie batter over your prepared graham cracker crust, spreading it lovingly to cover every inch. Place it in the oven and bake for 22-25 minutes until it is beautifully set in the middle.

When those brownies come out, switch your oven to broil on low. Top your warm brownies with mini marshmallows, chocolate chips, and peanut butter chips. Pop it back into the oven just until the marshmallows start to brown and everything becomes gooey. Be sure to keep an eye on it to avoid any burnt bits! Once done, let it cool for about 5-10 minutes before you dive in
