Preheat oven to 350 degrees F. Spray a 12 cup bundt pan with flour added baking spray.

In a medium bowl, thoroughly stir together flour, baking powder and salt.

In a mixing bowl, using a hand held mixer, beat together butter and sugar. Beat in eggs and vanilla and continue beating for 1 minute or until batter is light. Scrape sides of bowl. By hand, stir in flour mixture alternately with milk.

Pour half of the batter into pan. I weighed the batter, and half of the batter weighed about 24 ounces. If you have a scale, you can weigh out half the batter and pour the rest in. If not, just estimate.

Stir remaining ingredients (pecans, oats, brown sugar, cinnamon and applesauce) into remaining batter in bowl; Spoon into pan so that it sits on top of first batter.

Bake for 55-60 minutes. Cool in pan for 10 minutes. Turn from pan and let cool completely
