Step 1

Pre-heat the oven to 325°F. Butter a 9 X 9 baking dish, line with parchment paper, and then butter the parchment paper.

Step 2

In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

Step 3

In a medium saucepan over medium heat, melt the butter and whisk in the sugar and water. Cook until the sugar is dissolved. Take care not to brown the butter.

Step 4

Remove the saucepan from the heat and stir in the chocolate chips until melted.

Step 5

Very gradually mix in the eggs, starting with just a little, whisking in completely, and then adding a little more. This lets the eggs temper and not curdle in the warm chocolate. Stir in the vanilla.

Step 6

Mix in the flour mixture.

Step 7

Pour the brownie batter into the prepared baking dish and bake for 30-35 minutes. The brownies will puff up in the oven, but they'll fall some when they cool.

Step 8

Let the brownies cool completely before cutting.

Step 9

To make the sundaes, add a little dab of hot fudge into the bottom of a sundae dish. Top with a scoop of vanilla ice cream, a few tablespoons of hot fudge, whipped cream, nuts, and sprinkles.
