I have to admit I've never been much of a brownie fan.
They're overly sweet and just not as satisfying as chocolate.
On top of that, I can't think of many other desserts that are as costly as making brownies (maybe tiramisu comes in close, with cheesecake not too far behind)
You know?
Well, maybe you don't know....
Also, brownie batters are really friggin finicky. I can't tell you how many brownie batters I've had just come out greasy hard-as-a-rock blobs. The WORST is when you've gone out and bought this expensive-o chocolate for it. UGH. That is the WORST. I've researched far and wide for an answer to this, but I've come up with nothing. There are certainly people who complain about greasy brownies but no one will answer. Come on Chris Kimball where are you? Harold McGee? Alton Brown??? For the love of god, Nathan Myhrvold???

I think I have a semi-answer to my own question though.
OK, so there are two types of brownie batters. There's the cakey type where you start with the creamed butter+sugar. Then you add your eggs, then your melted chocolate, vanilla, flour mix. This batter never ever ever breaks. It turns out some pretty great soft brownie with the yummy crispy layer on top.
Then there's the fudgey type of brownie. These recipes start out differently. You melt the chocolate and butter together to create an emulsion. To that you add eggs (important that it's room temperature) and vanilla. This is where I've run into trouble in the past. For some reason or another adding the melted chocolate at the beginning always makes my sugar mix a bit grainy? And I know it's the chocolate that's doing this, because if you make blonde brownies (with no chocolate in sight, this problem never happens). The sugar seems to never completely melt. And I'm afraid to put it on the heat because you know, chocolate will burn before sugar even comes close to melting (which creates a whole other problem in its own right). Anyway, if anyone has any tips, please do share. I'd love to know the science behind this. I've looked at photos online as well, and everyone who makes brownies this way seem to have a much grainier batter than the other way. Anyway, at this point, you really want to beat the heck out of your mixture. Once you put flour in, you really can't mix for that long so I think it's imperative that the egg yolk help to emulsify the mixture before any sort of gluten product hits the batter. If the mix separates out... try another egg yolk. Technically, the emulsifying properties of yolks should help bring the troubled batter back together.
At this time, I'd like to point out that I've looked at several dozens of recipes online from Martha Stewart to Alton Brown to Rachel Ray, and a lot of these celeb chef just DO NOT go near the "fudgey brownie" recipes (with the exception of Martha Stewart). Rachel Ray goes by the tried and true cakey brownies, Alton skips the chocolate alltogether and goes for a pure cocoa powder brownie. Martha has a pretty standard recipe for fudgey brownies, though but sans any tips. Even Larousse and McGee are pretty mum on the subject.
Once you put in your flour (and cocoa, salt, baking powder, and what have you), you mix just until it's incorporated. And there. It's done! You put that in your pan, cover it liberally with whatever you like on top of your brownie, and stick that in the oven for half an hour-ish until the middle sets, but isn't over baked.

And then you pray pray pray to the brownie gods for a favorable outcome.
I really think I should spend a week or two studying why the order of adding chocolate is so important. Maybe we've all been doing it wrong and chocolate shouldn't be added until after you have a sugar/butter emulsion?? But at the same time, the beauty of having small grains of sugar in the batter = the yummy fudgey quality of the brownies?
Anyway, these Mint-chocolate Hazelnut squares turned out pretty great. The brownie gods were smiling down at me today, I suppose.
At the risk of this turning out like a food blog, recipe follows.

Mint-Chocolate Hazelnut Brownies
1c AP (all-purpose) flour
3T cocoa powder
1t espresso powder in 1t warm water
1/2t b.p. (baking powder)
1/2t salt
1/2c butter
4 oz chocolate + mint chocolate chips for sprinkling
1c sugar
1/3c nutella
2 large eggs
1 1/2t vanilla
1/4 c nuts (hazelnuts are obviously good, but walnuts will do OK as well)
1/4 c toffee bits
1. Preheat your oven to 375 degrees. Line a 8x8 pan with parchment paper and grease that baby up.
2. Combine AP flour, cocoa powder, baking powder, salt and set aside.
3. Being very very careful not to burn, melt your butter and chocolate in a double boiler or the microwave. Hint: Take it off the heat often and never stop stirring.
4. In a mixer, put in sugar and chocolate mixture and beat for 2 minutes. The texture will be a bit grainy.
5. Add eggs to the mixture, one at a time and beat beat beat for 3 minutes. Your batter will still have some sugar in it but the butter should not separate out. Add nutella, espresso mix and vanilla. Mix mix mix.
6. Add flour mixture and pray to the brownie gods that your mixture does not separate and mix only until all traces of flour are gone.
7. Pour batter into pan, "sprinkle" (more like release a flood of) mint chocolate chips, nuts, toffee on top. Bake for 30 minutes or until middle has set.
8. Let cool completely before cutting. This part is important especially for fudgey brownies. It's better, actually to keep it in the fridge, and when it's nice and cold, cut them up into 1" squares. It'll be amazing, I promise.
