Blueberry Crumb Buttermilk Muffins by Angela Roberts

You see a theme here lately; it’s blueberries. It’s what happens every July when the Golden Bell Blueberry Farm opens up for picking behind my house. This morning it was blueberry buttermilk muffins with crumb topping. I adapted the recipe from the Joy of Baking. I added in the crumb topping because I liked it so much from the this blueberry crumb pie.

I’m not the kind of person that easily quits. I always figure there are lots of ways to make one recipe and when I found myself with no butter for the crumb topping, I used olive oil. That worked and there was no after taste. The olive oil didn’t overpower, but I use a nice California extra virgin olive oil. Using butter would also work. I’m also in love with Irish butter.

I love the cinnamon flavoring in the crumb topping. It’s makes the blueberry crumb muffins taste like a coffee cake. I purposely made these on the small side, and very kid friendly using cupcake wrappers.  Be sure to fill the muffins almost all the way so they don’t look like cupcakes and get that awesome muffin top.

The biggest surprise with these muffins is how fast they disappeared. And I only ate one. This is probably still not the end of the blueberry festival at my house, merely one more merry berry recipe.

  1. Glad I found your crumb recipe. I had to go back to the original JOB recipe to confirm the oven temperature. Your instructions don’t cover that. You may want to consider adding the following to the above. I’m a proofreader by trade.

    Preheat oven to 375 degrees F (190 degrees C). Position rack in center of oven. Line with paper liners, or butter or spray, with a non stick cooking spray, 12 – 2 3/4 x 1 1/2 inch muffin cups.

    Thanks.
