📝 Preparation Steps
1
Day 1
2
Butter and line an 8-inch square (20 cm) baking pan with parchment paper, then set aside.
3
In a large bowl melt 2 ⅓ cups (14 oz/400 g) chocolate and butter gently in the microwave or in the top of a double boiler. Set aside to cool for ⏱️ 10 minutes.
4
To the chocolate, whisk in the eggs, brown sugar and vanilla extract and salt.
(7 oz/200 g) butter14 tablespoonslarge eggs, (at room temperature)6(12 oz/340 g) dark brown sugar2 cups(5 oz/142 g) all-purpose flour1 cup
5
Lastly, fold in the flour until combine and there are no streaks.
6
Transfer the batter into the prepared baking pan and sprinkle the remaining ½ cup (3 oz/85 g) chopped chocolate over the top, pressing in slightly.
7
Cover with foil and refrigerate for 3 full days (⏱️ 72 hours).

9
Place the pan straight into the oven and bake at 350°F (180°C) oven for about ⏱️ 40 minutes, until just set in the middle. A slight jiggle in the middle is what you want.
10
While still hot, cover the brownies with foil and place in the freezer for ⏱️ 30 minutes. This will help trap the moisture in the brownies to help with a fudge center.
11
After ⏱️ 30 minutes remove from the freezer and place in the fridge for ⏱️ 24 hours.

The Next Day

Cut up your brownies and enjoy! I like to serve these slightly warmed with Ice cream on top. Store leftovers in an airtight container at room temperature for up to 3 days. They also freeze really well for up to 4 weeks.
