I can't take credit for this one. This is a recipe I found in the Los Angeles Times. The cake does take a little time to prepare but it is very tasty. You would be surprised how well the sweet blueberries go with the tart lemon flavor. It is worth making especially if you get a sweet deal on your blueberries (I got mine at Trader Joe's). This cake is perfect with coffee or tea, that any coffeehouse best-to-offer sweet treats can't compare to this homemade delight.
Here is the recipe straight from the LA Times website. The only advice I have is to not add all the lemon glaze to the cake because the cake may become too lemony or overly sweet. Also, make sure you have a 9X9 pan. I didn't and had to split the batter to a loaf pan and an 8X8 pan and had to watch the cakes diligently in the oven. It worked out fine but was a bit of a hassel.
