Target recipe: preheat oven to 350 degrees. whisk together the yogurt and sugar to slightly dissolve the sugar. add the eggs one at a time, mixing thoroughly. stir in the vanilla, if using. sift together the cocoa powder, flour and salt. (sifting prevents lumps.) add the nuts, if using, to the sifted mixture. add half the dry mix to the wet mix and fold in with a wooden spoon. fold in the rest. do not over mix or the brownies will be cakey. pour into a 9x9 non-stick loaf pan and bake for 30-40 minutes. use a toothpick to test for doneness. the toothpick should have some moist crumbs sticking to it, not be totally dry. cool on a wire rack, then store the brownies in an airtight container to retain moistness.
