Ina Garten's recipe for fudge brownies with peanut butter swirls is not the best... I've got to be honest; when it comes to desserts, I love to get ideas and inspiration from Ina, but her actual recipes are way too buttery and sugary for me. The cloyingness takes away from the taste of the food. I like my pie crust to taste buttery, for example, but not like butter. And I like my brownies to be rich and deeply chocolaty, not syrupy sweet and oily.
A MUCH better brownie recipe is Alton Brown's recipe for cocoa brownies. His brownies are decadent, velvety, and somehow densely delicate - insanity.
My old roommate Bianca also makes a fantastic, chewy brownie that I love.
I've decided that cocoa powder works better for brownies than chocolate. However, I will be adding a peanut butter swirl from now on to whatever brownie recipe I use.
