Banana, Raisin & Walnut Baked Oatmeal

Preheat oven to 375 degrees F. Coat an 8-inch-square baking dish with cooking spray.

Mix oats, walnuts, cinnamon, baking powder, salt and allspice in a large bowl. Combine milk, yogurt, oil, brown sugar and vanilla in a medium bowl. Add the milk mixture to the dry ingredients; stir until completely incorporated. Stir in bananas and raisins. Pour the mixture into the prepared baking dish.

Bake until golden on top and firm to the touch, 45 to 50 minutes.
