"I too doubled the recipe for a 9x13 pan and baked for an hour. I also added a small amount of milk to thin the batter a bit. When it came out of the oven I also a topped it with a can of vanilla frosting. I heated the frosting in the microwave for a minute and then poured it over the hot coffee cake. It makes it extra moist! My family devoured it!"

"I normally double the recipe and prepare a 13x9 dish to carry to social gatherings. The cake is always a hit. My family loves this moist cake. I do reduce the blueberries by 1/2 a cup (1 cup for double) and add a pinch of cinnamon to better suit our personal preferences."

"Replaced vanilla extract with lemon extract, added a splash of milk to the batter (was a little dry after stirring wet ingredients into dry mixture), and doubled the topping like another review recommended. It turned out better than last time! Definitely a new family favorite in our home."

"I've been using this recipe for a few years now. Made it for our local county fair last year and got second place! Very good recipe!"

"This has roughly half the calories and fat of the Blueberry Sour Cream Coffee Cake on this site (the one pictured as a bundt cake). While that recipe is fabulous, I wanted to try this recipe which makes a smaller, lower calorie cake. I made a few changes (used 1/3 cup whole wheat flour, the rest all-purpose flour; used nonfat yogurt for half the sour cream, and used regular sour cream). It was moist and flavorful, but next time I will increase the amount of topping because it wasn't noticeable enough."
