Rhubarb Streusel Muffins

~from Savoring Time in the Kitchen

Makes about 24, depending on how full the muffin cups are filled. 

2 1/2 cups flour
1 teaspoon baking soda
1 teaspoon baking powder
1/2 teaspoon salt
1 cup brown sugar
1/2 cup vegetable oil
1 egg
1 teaspoon vanilla extract
1 cup buttermilk
2 1/2 cups diced rhubarb
1/2 cup chopped pecans

Streusel Toppping:

1 tablespoon melted butter
1/3 cup brown sugar
1-1/2 cinnamon

Preheat the oven to 350 degrees F (175 degrees C).

Spray 12 cup muffin pans with non stick baking spray (with flour added - such as Bakers Joy) or line with paper liners.

In a 3 cup bowl, stir together the flour, baking soda, baking powder and salt.

In a stand mixer or large bowl, beat the brown sugar, oil, egg, vanilla and buttermilk with an electric mixer until smooth. Pour in the dry ingredients and mix by hand just until blended. Stir in the rhubarb and chopped pecans.

In a small bowl, mix together the melted butter, brown sugar and cinnamon until blended together.

Spoon the batter into the prepared cups, filling almost to the top, and then sprinkle with about 1 teaspoon or so of the streusel mixture. 

Bake in the preheated oven until the tops of the muffins spring back when lightly pressed, about 25 minutes. Cool in the pans for about 10 minutes before removing.
