Blueberry buckle

Hanging out with my dad is like living in a test kitchen. Dad's baking experiments are the bane of anyone's low carb diet. One must have formidable willpower to resist his creations, and fortunately for my taste buds, I don't. This morning we baked a blueberry buckle, the recipe of which was retrieved from an aging newspaper clipping, cut years ago. (When I say "we", my participation included observing the ingredients the night before, sleeping in this morning, and photographing and documenting the results.) What is a buckle you might ask? According to the recipe, a buckle is an old-fashioned, single-layer cake with a streusel-type topping. The batter is quite dense. As the cake bakes, the batter sinks to the bottom of the pan, which makes the streusel buckle on top. In other words, a coffee cake. It in fact tastes much like our family favorite apple coffee cake, but with blueberries instead, like one giant blueberry muffin. Delicious.
