This might be the PERFECT fall coffee cake - for bake sales, guests, host gifts...we like discovering excuses to make it!
For the Streusel: Mash together all of the streusel ingredients, except the pecans, in a small bowl. I like to start with a fork and then get in their with my fingers. The mixture should feel like wet sand, then mix in the chopped pecans; set aside.
For the Coffee Cake: Whisk together the flour, baking powder, baking soda and salt in a large mixing bowl to aerate and combine; set aside, making a well in the center.
