adapted from:
NOTE: This recipe was edited on 1/14/10 to delete the baking powder
Makes 2 9"x5" loaves

Note: This recipe uses my gluten-free flour mix:
Jeanne's Gluten-Free All-Purpose Flour Mix (mix together and store in fridge):
1 1/4 C. brown rice flour
1 1/4 C. white rice flour
1 C. tapioca flour
1 C. sweet rice flour (also known as Mochiko)
2 scant tsp. xanthan gum

(you can also use the gluten-free flour mixture (not baking mix) of your choice--just be sure it contains xanthan gum. Or, you can add 1/4 tsp. xanthan gum per cup of gluten-free flour. If you use bean flour, it will add a bean taste to the cake)

Special equipment needed
-a stand mixer is very helpful, but a hand mixer will do
-2 9"x5" loaf pans

3 C Jeanne's Gluten-Free All-Purpose Flour Mix
2 tsp salt
1 1/2 C (3 sticks) unsalted butter, softened
1 package (8 oz) cream cheese, room temperature
