Blueberry Crunch Coffeecake

This recipe is from Joy of Cooking. It turned out really tasty on the first try. The recipe calls for sliced almonds, which I didn't have, but I had roasted almonds so I just chopped those up. You mix dark brown sugar with the almonds and sprinkle the mixture in the bottom of a loaf pan. Then spread the blueberry cake batter over top. (The batter is similar to a muffin batter.) When it bakes, the brown sugar and almonds form a crunchy layer. You serve the cake (loaf?) inverted so the crunchy almond layer is on top. Yum!
