- 9×13 inch baking pan – for the perfect brownie size.

Directions: Chocolate Peanut Butter Cup Smores Brownies

Step 1: Prepare the Crust
Start by preheating your oven to 350°F (175°C). In a bowl, combine the melted butter, crushed graham cracker crumbs, sugar, and a pinch of salt. Mix well until all the crumbs are evenly coated. Press this mixture firmly into the bottom of a greased 9×13 inch baking pan to create your crust.
Step 2: Make the Brownie Batter
In a double boiler, melt the 8 tablespoons of unsalted butter and the chopped unsweetened chocolate together, stirring until smooth. Once melted, remove from heat and let cool slightly. In a large bowl, whisk together the light brown sugar, white sugar, vanilla extract, and salt. Add in the melted chocolate mixture and mix until well combined.
Step 3: Add the Eggs and Flour
Add the cold eggs one at a time, mixing well after each addition. Once fully incorporated, gently fold in the all-purpose flour until just combined. Be careful not to overmix; a few lumps are okay!
Step 4: Assemble and Bake
Pour the brownie batter over the prepared graham cracker crust, spreading it evenly. Bake in the preheated oven for about 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
Step 5: Add the Toppings
Remove the brownies from the oven and immediately top them with the mini marshmallows and halved peanut butter cups. Return to the oven and bake for an additional 5-7 minutes, or until the marshmallows are golden and puffed.
Step 6: Drizzle with Peanut Butter
Once the brownies are out of the oven, drizzle the melted peanut butter over the top while they are still warm. Allow the brownies to cool in the pan before cutting into squares.

If you have specific dietary requirements, here are some easy substitutions you can make:

Ask & Learn
Can I use different types of chocolate in the brownies?
Absolutely! You can use semi-sweet or dark chocolate if you prefer a different flavor profile. Just ensure it’s unsweetened if you want to maintain the balance of sweetness in the recipe.
What can I substitute for graham cracker crumbs?
If you don’t have graham crackers, crushed digestive biscuits or vanilla wafers work well as substitutes for the crust.
How can I make these brownies more chocolatey?
For an extra chocolatey kick, consider adding chocolate chips to the brownie batter before baking. They’ll melt into the brownies, enhancing the chocolate flavor.
Is there a way to make these brownies less sweet?
You can reduce the amount of sugar in the brownie batter or opt for dark chocolate, as it tends to be less sweet than milk chocolate. Experimenting with bittersweet chocolate can also help balance the sweetness.
