Transform ordinary cake mix into extraordinary cakes through just the right additions: Use buttermilk and sour cream for greater moisture and richness. Boost flavor with cocoa powder, peppermint extract, lemon zest--even lemon yogurt. Instead of water, try orange juice, canned pumpkin, a leftover cup of coffee (it makes for a devilishly delicious brownie).
