Pecan Brown Sugar Crumble Topping

1. In a bowl, whisk together the chopped pecans, flour, brown sugar, granulated sugar, cinnamon, and salt until evenly combined. Add the butter and rub in with hands until the entire mixture is crumbly and slightly moist, with no big chunks of butter remaining. Chill in fridge while preparing the coffee cake batter.

Maple Banana Coffee Cake

1. Preheat oven to 350ºF and grease an 8" square baking pan with cooking spray.
2. In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well-combined. Set aside.
3. In a large bowl, combine the vegetable oil and brown sugar and whisk together until well-combined. Add the egg and whisk in until smooth. Add the yogurt and maple flavor and whisk in until the mixture is fairly smooth. Whisk in the mashed banana until combined.
4. Add the dry ingredients to the wet and fold in until just combined; don't overmix! A few small specks of flour visible are fine as they should get mixed in as you transfer the batter to the baking pan.
5. Pour the batter into the prepared pan and smooth out the top in an even layer. Sprinkle the crumble topping evenly over the batter. Bake for 45-50 minutes, until a toothpick inserted into the center of the cake comes out clean.
