Melt butter and let it cool completely. Beat butter with eggs and evaporated milk. Then add flour, 1 1/2 cups sugar and baking powder and continue to beat the mix until it is fully incorporated. Grease and flour a pan and put peeled and sliced apples on the bottom. Combine the nuts, 1 cup sugar and cinnamon; put half of this mixture over the apples. Then on top of this add the (butter, eggs, flour) mixture and top with the other half of the nuts-sugar-cinnamon mixture. Bake at 350 degrees. Serve warm.
