@bengingi: CORRECT CRUMB TO CAKE RATIO IS THE SECRET FOR A SUPERB COFFEE CAKE! This sour cream coffee cake is all about that contrast- buttery, crisp crumb on top and a tender, fluffy cake underneath. I used the new self-rising flour from @Bob’s Red Mill and it made this one extra light, extra easy, and bakery-level good. Perfect with coffee, even better the next day, and absolutely dangerous to keep on the counter. Full recipe is on my website BenGingi.com YASSS!
