My ex-wife Judy prepared these at my son's last birthday and I finally found the recipe. I know it sounds strange, but the recipe is really good. my ex mother-in-law used to make the best apple dumplings and these are actually quite close to hers and very easy to make.
Mountain Dew Apple Dumplings
2 large Granny Smith apples (Judy used gala)
2 (10 oz) refrigerated crescent roll dough tubes
1 cup butter
1 cup sugar
1 tsp. sugar
1 tsp. vanilla
1 can Mountain Dew
Heat oven to 350 degrees. Grease a 9x13 pan. Core each apple and cut into eight wedges each. Separate dough into triangles. Roll apple wedge into dough, starting at small end; pinch to seal and place in baking dish. ( At this point, Judy sprinkled extra sugar and cinnamon onto the prepared dough in pan.)
Melt butter in saucepan and add sugar and cinnamon, pour over dumplings. Pour Mountain dew around sides and down the middle of the pan, but not over the dumplings. You do not use the whole can, probably half. Bake 35 to 45 minutes and let them sit 10 minutes before serving.
