Big Crumb Coffee Cake

Big Crumb Coffee Cake

I’m sure when you saw last weekend’s rhubarb post you were wondering why I didn’t make one of Deb’s many rhubarb recipes. Well, that’s because I can usually count on getting rhubarb at my farmer’s market for a few weeks running, so I knew I’d have another chance. I chose the Big Crumb Coffee Cake because I love coffee cake, but am often disappointed by a stingy amount of streusel.

This is truly one of those “Why haven’t I made that?” moments. While this recipe is from 2008, I know I only bookmarked it sometime in the last couple of years, probably after Deb resurfaced it during rhubarb season. I’m not sure why I didn’t make it; probably because it didn’t seem very dessert-y.

This is a pretty straightforward recipe, though you will feel like you’ve used half the bowls in your kitchen. (I went through five.) You toss the rhubarb with sugar and cornstarch, make a very sturdy streusel, and put together a thick batter. You spread the batter into the pan and top it with huge chunks of streusel.

This does need to be in the oven for a while — 45 to 55 minutes. It’s hard to tell when this is done due to the rhubarb. At 45 I put mine back in for 5 minutes, but should have given it 10, maybe 15. The sides and some parts of the top were a lovely golden brown, but it turned out the very middle was tragically underbaked. So, if you make this pay careful attention to that, especially if you’re using a glass baking pan. (I was, and in retrospect I should have dug out my metal pan.)

You do also want to let it cool. Maybe not quite completely, but cooling allows the streusel to firm up a bit and that gives you a nice textural contrast to the soft cake and jammy rhubarb.

Despite the near-total loss of the center piece, this was delicious. Rhubarb in coffee cake is such an unexpected combination, I really think you should try this. And as Deb suggests I think this would work well with other tart fruit; in particular I’m curious to try this with blueberries. But if you like your coffee cake uncluttered this would be just as good without fruit. (Maybe use a heavy hand on the vanilla.)

I put about half of this in the freezer and will report back on how it holds up. I didn’t do anything special to it, just threw the pieces into a plastic container and stuck it on the bottom of the freezer. It’ll be nice to have on hand the next time we’re sad that we’re out of bagels.

Truly, look at these huge pieces of streusel. I forgot to take a picture of the Big Crumb Coffee Cake after it came out of the oven so you’ll just have to imagine how good it was.
