Brazilian-Style Carrot Cake with Chocolate Sauce
I've also tried adding the flour and baking powder to the blender and mixing the batter that way, but it depends on the blender.
Substitute powdered chocolate drink mix (such as Nesquik(R)) for the cocoa powder if desired, but reduce sugar by 1 tablespoon if doing so.
Any kind of chocolate frosting goes well with this cake. Try chocolate ganache!
