Strawberry Rhubarb Coffee Cake

Although my coffee cake makes a large pan, it never lasts very long! It's great for a Sunday brunch after church and nice to bring to family reunions, too. —Dorothy Morehouse, Massena, New York

    This was a tasty coffeecake. I put it in a 10x15 high sided pyrex dish and it was bubbling over the top towards the end of the baking cycle. I cannot imagine that it would fit in a 9x13 without a horrible mess in the oven. I baked it 45 min, thought it needed a few more minutes (hard to tell with the straw/rhubarb bubbling), but in hindsight, I should have taken it out at 45. The bottom is a bit dark but not burnt. I only used 3/4 cup of sugar in the fruit part and would probably even use less next time as I like tart things. Also added cinnamon as another review suggested. Very good coffeecake and will make again.

    I changed this recipe up a bit. I decided I wanted the crumb top only. So I made the straweberry rhubarb filling first. Then I whisked the first 5 dry ingredients together . Next I melted the butter and added it to those first 5 dry ingredients . I mixed well with first a spoon and then with my using my clean hands. Then I took half out and mixed iin 3/4 cup sour cream (didn't have buttermilk) and one egg into 1/2 of the mixture and stir to mix well. Pour this batter into the greased and floured pan and add your cooled filling. Take the other half of crumbs and spread over the top! Bake as directed. Cool and cut into bars! Vert good!

    This coffee cake is amazing! Perfect amount of fruit. Cake is nice and moist, not dried out like many coffee cakes and just the right amount of topping. The only thing I added was a heaping teaspoon of cinnamon just because I like cinnamon in my coffee cakes. This is a real keeper recipe. Even people who think they don't like rhubarb loved this recipe. Thank you so much for posting this!
