There comes a time in Argentine cooking school when they decide to teach you how to make "American" baked goods.
The Argentine word for brownie? Brownie. The recipe used melted chocolate, similar to this one for Triple Chocolate Brownies, which is earth-shatteringly good.
The Argentine word for muffin? Muffin. These had "red fruits" in them.
These were delicious: Marbled and Lemon pound cake w/ chocolate and lemon glazes.
