My Favorite Blueberry Buckle Recipe

I can't say I "grew up" with blueberry buckle but when my mom found Martha Stewart's mom's recipe and gave it a try, it became a family favorite, especially for The Husband. He looks forward to blueberry buckle every summer, when the Michigan blueberries are ripe and available at our local markets. I love fresh sweet blueberries, but you can make this recipe year round with any fresh blueberries that you can locate. Frozen might work but I think they would turn the batter purple. :)

The recipe calls for a ton of blueberries and my mom ususually doesn't use as many and I didn't either, and a double batch does fit nicely in an 11x17in glass dish I think. The one thing I noticed this last time I made it was that it really needed to bake a little longer and I think I was using a lower temperature because I thought my oven was running hot, but I should've kept it in longer. My tester toothpick came out juicy but because of all the berries it was hard to tell, I thought "well it's probably done, it's been that long" but unfortunately, by the time I got to Andrea's family picnic, I found out the inside was a little mushy. Luckily everyone just thought that was my intent and they seemed to like the buckle anyway.

The cinnamon streusel topping is perfect and I use it for my triple berry tart recipe as well. Overall, this is a great recipe that makes a the best blueberry buckle that I've tried, very moistmoist blueberry buckle so I hope you give it a try if you're looking for a summer dessert! If you were to bring this over to some one's house, they will surely be thrilled. :)
