In a small bowl combine the topping ingredients. Use your fingertips and rub the butter into the other ingredients until it resembles crumbs. Place in the refrigerator until ready to use.

Preheat the oven to 350 degrees. Place a sheet of parchment paper or foil in the bottom and up the sides of a 9 x 13 baking dish.

Place the butter in a small saucepan. Heat for 5-10 minutes or until the butter has browned. Remove from heat and let cool for 5 minutes.

In a medium bowl combine the flour, oats, baking powder, cinnamon, and ginger. Set aside.

In a large bowl combine the brown sugar, eggs, and vanilla. Mix well. Add in the brown butter and mix until well combined.

Add the pears to the flour mixture and toss to coat. Add the flour mixture to the wet ingredients and mix well.

Spread the blondie mixture into the bottom of the prepared baking dish. Smooth into the pan with a spatula.

Sprinkle the blondies with the crumb topping. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean.

Cool completely on a wire rack. Cut into 24 squares and enjoy.
