• Total Time: Chilling Time + 1 hour
• Servings: 24 brownies
• Yield: 24 brownies
• Dietary Type: Not Gluten-Free

Ingredients

• 4 ounces unsweetened chocolate
• 2/3 cup unsalted butter
• 1 1/4 cups semi-sweet chocolate chips, divided
• 1 1/3 cups all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 4 large eggs, at room temperature
• 2 cups granulated sugar
• 2 teaspoons vanilla extract
• 1 (10 1/2 ounce) bag miniature marshmallows
• 1 1/2 cups milk chocolate chips
• 1 cup smooth peanut butter (do not use natural peanut butter)
• 1 tablespoon unsalted butter
• 1 1/2 cups Rice Krispies

Equipment Needed

• 9×13-inch baking pan
• Medium saucepan
• Medium bowl
• Large bowl
• Whisk
• Spatula
• Sifter (optional)

Instructions

1. Preheat your oven to 350 degrees F (175 degrees C). Grease a 9×13-inch pan. Ensure every corner is well-greased to prevent the brownies from sticking.

2. For the brownies: In a medium saucepan, combine the unsweetened chocolate, butter, and ¾ cup of the semi-sweet chocolate chips. Melt over medium heat, stirring occasionally, until smooth. It’s crucial to stir constantly to prevent the chocolate from scorching. Once melted, remove from heat and set aside to cool for 5 minutes. This cooling period is important because you don’t want to cook the eggs when you add them to the chocolate mixture.

3. In a medium bowl, sift together the flour, baking powder, and salt. Sifting the dry ingredients ensures they are evenly distributed, resulting in a lighter and more tender brownie. If you don’t have a sifter, whisk the ingredients thoroughly to achieve the same effect. Set aside.

4. In a large bowl, whisk the eggs thoroughly until they are light and slightly frothy. This incorporates air into the batter, which contributes to the brownie’s texture.

5. Add the sugar and vanilla extract to the eggs and whisk until well blended. The mixture should be smooth and slightly thickened.

6. Stir the melted chocolate mixture into the egg mixture, mixing well until everything is thoroughly combined. Avoid overmixing at this stage; mix just until the ingredients are incorporated.

7. Stir in the dry sifted ingredients, mixing until just combined. Again, be careful not to overmix, as this can lead to tough brownies. Fold in the remaining ½ cup semi-sweet chocolate chips.

8. Pour the batter into the prepared pan, smoothing the surface with a spatula. Ensure the batter is evenly distributed for uniform baking.

9. Bake for 25 to 30 minutes, or until a cake tester inserted into the corner of the pan comes out with moist crumbs. Be careful not to overbake, as this will result in dry brownies. The center should still be slightly soft.

10. Remove the brownies from the oven and immediately sprinkle the miniature marshmallows evenly over the top.

11. Return the pan to the oven for 3 more minutes. This allows the marshmallows to melt and become gooey, creating that signature marshmallow layer. Watch closely to prevent the marshmallows from burning.

12. Meanwhile, prepare the peanut butter crunch topping: Place the milk chocolate chips, peanut butter, and tablespoon of butter in a medium saucepan. Melt over low heat, stirring constantly, until completely melted and smooth. Using low heat is essential to prevent the chocolate from seizing or burning.

13. Remove from heat and add the Rice Krispies, mixing well until the cereal is evenly coated with the peanut butter chocolate mixture.

14. Allow the mixture to cool for 3 minutes. This will help it thicken slightly, making it easier to spread over the marshmallow layer.

15. Spread/Pour the Rice Krispies mixture evenly over the marshmallow layer. Gently press down to ensure it adheres to the marshmallows.

16. Refrigerate the brownies until chilled before cutting. This allows the layers to set, making them easier to slice and serve. The chilling time also enhances the flavors.

Expert Tips & Tricks

• Room temperature eggs: Using room temperature eggs helps them incorporate more easily into the batter, resulting in a smoother and more uniform texture.
• Don’t overmix: Overmixing the batter can lead to tough brownies. Mix just until the ingredients are combined.
• Evenly distributed marshmallows: Ensure the marshmallows are evenly distributed over the brownies to prevent some areas from being overly gooey while others are lacking.
• Perfectly melted chocolate: Low and slow is key when melting chocolate. Use a double boiler or a heatproof bowl set over a simmering pot of water to prevent scorching.
• Adjust baking time: Baking times may vary depending on your oven. Start checking for doneness around 25 minutes and adjust accordingly.

Serving & Storage Suggestions

These brownies are best served chilled, which allows all the layers to set properly and the flavors to meld together. Cut them into squares and serve as is, or with a scoop of vanilla ice cream for an extra decadent treat.

To store leftovers, keep them in an airtight container in the refrigerator for up to 5 days. You can also freeze them for up to 2 months. To thaw, simply place them in the refrigerator overnight. They can be enjoyed straight from the fridge or warmed slightly in the microwave for a gooey treat.

Variations & Substitutions

• Different Cereal: Experiment with different cereals like Cocoa Krispies or Fruity Pebbles for a colorful and flavorful twist.
• Nuts: Add chopped nuts like pecans or walnuts to the peanut butter crunch topping for added texture and flavor.

FAQs (Frequently Asked Questions)

Q: How do I prevent the marshmallows from burning?

A: Keep a close eye on the brownies while they are in the oven with the marshmallows. If they start to brown too quickly, tent the pan with foil.

Q: Why are my brownies dry?

A: Overbaking is the most common cause of dry brownies. Start checking for doneness around 25 minutes and remove them from the oven when a cake tester inserted into the corner comes out with moist crumbs.
