Rhubarb-raspberry coffee cake for the secret society

It's my turn to provide nutrition for a secret society and the manager of the household provisions commanded "Empty the freezer!". So this is what we ended up with for the secret society, will they approve?

Credit goes to the original "Bun on the Run" sisters, but also to the famous night baker and the new Bun Runner for the idea to press the streusel into the cake before baking. We'll see if it lasts till morning.
