6oz(170 grams) good-quality dark chocolateat least 60%, chopped
1/3cup(80 grams) white granulated sugar
¼teaspooncoarse kosher salt
1teaspoonpure vanilla extract
2large eggs
½cup(60 grams) all-purpose flour
Instructions
Preheat your oven to 350 degrees F and grease a 8×8 inch square pan. (or 25 cm | 10-inch loose-bottomed tart tin).
In a medium saucepan, melt down the butter and Nutella. Remove from the heat and add the chocolate, letting it sit for a minute or so to melt from the residual heat. Then whisk it all together to make a beautiful glossy mess.
Add in the sugar, salt, and vanilla extract and whisk to combine. Add the eggs one at a time, fully incorporating the first before adding the second. Carefully add the flour and mix just until the flour disappears.
Pour into the prepared pan and bake for 25–30 minutes until the top is nice and glossy and sort of crackled. It won’t look 100% done when you take it out but that means not having a dry hockey puck. Let cool completely before serving and powdered sugaring to ensure the best texture and not dissolving your decoration. Eat warm with no-churn pumpkin ice cream!
