### Ingredients Breakdown
For the Brownies:
- Unsalted Butter: Use high-quality butter for the richest brownies.
- Dutch Process Cocoa Powder: Adds a deep chocolate flavor—you can substitute with regular cocoa powder if needed.
- All-Purpose Flour: Creates the perfect fudgy-yet-structured brownie.
- Eggs: For a rich, dense texture. Use room temperature eggs for the best results.
- Sugar: A mix of white and brown sugar keeps these brownies moist with a slight caramel note.
- Salt and Vanilla Extract: Enhances the chocolate flavor—don’t skip these!
For the Hot Chocolate Sauce:
- Milk: Regular or whole milk works best for an ultra-creamy sauce.
- Semi-Sweet Chocolate Chips: Go for a good brand; the better the chocolate, the better the sauce!
- Marshmallows: Melt right into the sauce for a kitschy hot cocoa vibe.
- Whipped Cream (Optional): Because more is more.
### Step-by-Step Instructions
Make the Brownies:
- Preheat the oven to 350°F (175°C) and line a 9×9-inch baking pan with parchment paper.
- In a medium saucepan, melt the butter over low heat. Remove from heat and whisk in cocoa powder until smooth.
- Stir in the sugars, followed by the eggs one at a time. Add the vanilla extract and a pinch of salt.
- Sift in the flour and fold gently until combined. Be careful not to overmix!
- Pour the batter into the prepared pan and smooth out the top with a spatula. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. Cool slightly.
Prepare the Hot Chocolate Sauce:
- In a small saucepan, heat the milk over medium heat just until steaming (don’t let it boil).
- Add the chocolate chips and stir until melted. Toss in a few marshmallows and let them melt for extra creaminess.
- Transfer to a serving bowl or pour directly into a small pitcher for drizzling.
Assemble the Sundaes:
- Cut the brownies into squares and place one on a serving plate or bowl.
- Add a scoop (or two!) of your favorite ice cream—vanilla is classic, but anything goes here.
- Drizzle generously with warm hot chocolate sauce, then top with whipped cream, sprinkles, nuts, or more marshmallows.

### Chef’s Tips and Tricks
- Don’t Overbake: The brownies should be slightly underdone for that gooey, fudgy texture.
- Warm the Brownie Before Serving: A quick zap in the microwave will make them extra decadent.
- Pre-Make the Sauce: The hot chocolate sauce can be made ahead of time and reheated gently over low heat.
### Recipe Variations and Serving Suggestions
- Flavor Swap: Try peppermint chocolate sauce for a festive spin or peanut butter sauce for a nutty twist.
- Dairy-Free Option: Use coconut cream instead of milk and vegan chocolate chips for a lactose-free dessert.
- Pair It Up: Serve alongside a rich espresso drink or a tall glass of chilled milk for a perfect pairing.
### FAQs
How Should I Store Leftovers?

Can I Freeze This?
Absolutely! Wrap individual brownies tightly in plastic wrap and freeze for up to three months. Thaw them at room temperature or warm them in the microwave before serving.
