Snickers Brownies (ChocoSmash Bar Copycat): Step-by-Step Guide

Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). This ensures that your brownies will bake evenly.
Step 2: Prepare Your Baking Pan
Grease a 9×13 inch baking pan with 1 tablespoon of vegetable oil or line it with parchment paper for easy removal later.
Step 3: Mix the Brownie Batter
In a large mixing bowl, whisk together the vegetable oil, granulated sugar, and cocoa powder until well combined. Add the eggs, vanilla extract, and water, mixing until smooth. Stir in the salt and flour until just combined; be careful not to overmix.
Step 4: Bake the Brownies
Pour the brownie batter into the prepared baking pan and spread it evenly. Bake for about 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Remove from the oven and let it cool slightly.
Step 5: Layer with Marshmallow Fluff
Once the brownies have cooled slightly, spread the marshmallow fluff evenly over the top while the brownies are still warm. This will help the marshmallow fluff to melt slightly and adhere better.
Step 6: Prepare the Caramel Layer
In a microwave-safe bowl, combine the unwrapped caramels and 3 tablespoons of milk. Microwave in 30-second intervals, stirring in between, until the mixture is smooth and creamy. Pour the caramel over the marshmallow layer, spreading it evenly.
Step 7: Add Peanut Butter and Chocolate
In another microwave-safe bowl, combine the creamy peanut butter and 1 cup of chocolate chips. Microwave in 30-second increments until smooth, stirring after each interval. Drizzle this mixture over the caramel layer, using a spatula to create an even layer.
Step 8: Top with Chocolate Chips and Peanuts
Sprinkle the remaining chocolate chips and chopped peanuts over the top of the peanut butter layer, pressing them in slightly to ensure they stick.
Step 9: Final Bake
Return the brownies to the oven for an additional 10-15 minutes, just until everything is warm and melty. Keep an eye on them to prevent burning.
Step 10: Cool and Slice
Once baked, allow the brownies to cool completely in the pan on a wire rack. Once cooled, lift them out using the parchment paper (if used) and slice them into squares.

Leftovers & Meal Prep
If you have leftovers, store them in an airtight container at room temperature for up to five days. For longer storage, consider freezing the brownies.

Just thaw them at room temperature or warm them slightly in the microwave before serving.
