Blueberry Mystery Cake

Rated as 4.45 out of 5 Stars

"This recipe is a childhood favorite that my grandma passed to my mom and now I am passing to my own kids! It is quick and easy, and great for summer picnics. Plus, the little ones are fascinated when I tell them the boiling water is the 'mystery' behind the cake. Also great with a scoop of vanilla ice cream on top!"

We really liked this cake. I would say it is more like a cake-like pie. I guess my pan wasn't deep enough because it overflowed. . .thank goodness I had the pan on top of a cookie sheet.

Tasty & easy but not much different than other fruit cobbler type recipes. No one jumped up for seconds.

To be fair, this is more of a cobbler than a cake. But I can tell after making it once, I will be making this regularly. I followed directions exactly, except I used my frozen berries from las...
