This mile-high Blueberry Streusel Layer Cake is extra-tall, extra-gorgeous, and extra-delicious! It’s a twist on the usual blueberry cake recipe, with six moist rounds of sour cream cake, layered with fresh blueberry sauce and sprinkled with streusel in between. This cake is assembled using a "double barrel" method, meaning it is actually two cakes stacked on top of each other, with a cake board and dowels in the middle for extra support. Note that this cake's components and assembly require a lot of baking and chilling time, so be sure to read through the recipe before beginning and give yourself plenty of time for everything. Each component includes instructions for making it in advance, if you want to split the recipe up over several days.
