Make-Ahead Blueberry-Lemon Coffee Cake
Wouldn’t it be great to have homemade coffee cake at a moment’s notice? But making our own mix turned out to be a bit of a puzzle.
Why This Recipe Works
For homemade coffee cake with the ease of a boxed mix, the freezer was key. For the topping, a simple streusel full of nuts and spices went into one zip-top bag. Along with flour, sugar, spices, and leavener, we found that buttermilk powder in our cake mix was an ideal “dry” replacement for the sour cream in our favorite coffee cake recipe. By using the food processor, it was possible to pulse the butter in with the dry ingredients before transferring it to the freezer in a bag of its own. When it comes time to bake, we simply combine our dry mix with eggs and milk (warmed to melt the butter), top it with the streusel, and bake.
