Preheat oven to 350 degrees. Grease and flour a 10 inch Bundt pan. I grease and flour twice to ensure the cake comes out perfect, but it's not required.
In a large mixing bowl fitted with the whisk attachment, combine cake mix and pudding mix. Next add water, applesauce, eggs, oil, and lemon extract.
Beat on low speed until mix appears blended. Scrape bottom of bowl (there will be unmixed flour), and beat 4 additional minutes on medium speed. Pour batter into prepared pan.
Bake in the preheated oven for 50-60 minutes, until a toothpick inserted into the center of the cake comes out with a few moist crumbs.
Let cool in pan for 10 minutes, then turn out onto a wire rack and cool completely.
