Fat Witch Brownies

14 Tablespoons (1 3/4 sticks) unsalted butter
1/2 cup + 2 Tbsp bittersweet chocolate chips (I used 120 grams of 72% Trader Joe's Dark Chocolate - see my notes)
1 1/4 cups granulated sugar (I used 250 grams sugar)
4 large eggs, room temp
1 tsp pure vanilla extract
1/2 cup + 2 Tbsp unbleached flour (I used 88 g flour)
Pinch of salt

Oven Temp: 350 F. Be sure to preheat.
Pan: 9 x 9 square baking pan

1. Grease and flour the baking pan. I lined it with parchment paper and sprayed it with a bit of Pam with Flour.
2. Chocolate measuring: I did not have bittersweet chips, but I did have a Trader Joe's bar of 72% chocolate. I ended up weighing semi-sweet chips and then cutting enough of the 72% chocolate to match the weight. Oh, how I wish all cookbooks just gave us the weight (especially since the measurement 1/2 cup + 2 T signifies that this was originally a weight measure and you had to convert it to measuring cups). You don't need to have chips because you are melting the chocolate so weights would have been great to have. Hint, Hint to all cookbook publishers!)
3. Melt butter and chocolate in a small saucepan over low heat, stirring frequently.  Set aside to cool. (I melted the butter and chocolate in a double boiler (large bowl over low simmering water that doesn't touch the bowl)). 
4. Cream sugar, eggs and vanilla together. Add cooled chocolate mixture and mix until well-blended.
5. Measure flour and salt and then sift together directly into the chocolate mixture. Mix batter gently until well combined and no trace of the dry ingredients remains. (I used a spatula and folded in the flour mixture).
6. At this point, if desired, stir in any extras like walnuts. (I did not include nuts)
7. Spread batter evenly in the prepared baking pan and bake 33 minutes or until a toothpick inserted in center comes out clean or with only crumbs, not batter, on it. (I baked mine for 33 minutes...probably could have taken them out at 31 or 32 minutes).
8. Remove from oven and cool on rack for 1 hour.
