In a large bowl mix yeast, 2 cups flour, oats, and salt. In a microwave safe bowl combine the milk, water, butter, sugar, and honey heat in microwave until warm about 110 degrees F to 115 degrees F. Add the liquid mixture to the dry ingredients and stir with a wooden spoon. Add the eggs and mix in until combined.

Gradually add the rest of the flour. Using your hands to knead the dough while adding the flour. You will add enough dough until it is slightly sticky. Knead until the dough is smooth. Grease the bottom of the bowl with shortening and turn over to coat both sides.

Cover and let rise for about an hour or until double in size.

While the dough is rising, combine the sugar and cinnamon for the filling. Chop the apple, you will want to chop it is very fine pieces so that it is not raw after the roll are baked.

Once the dough has doubled in size, divide into two balls. Grease your working surface with shortening and pat out the first ball to a 12 by 10-inch rectangle.

Spread half of the softened butter for the filling over the dough. Sprinkle half of the sugar and cinnamon mixture over the butter. Sprinkle the chopped apple over the cinnamon and sugar mixture. Start rolling the dough as tightly as you can. With a pair of scissors cut the roll into 12 sweet rolls. Repeat with the second ball of dough.

Place the rolls in a greased 9 by 13-inch pan. Cover and let rise for 30 minutes so they are about double in size.

Preheat oven to 375 degrees F. Bake the rolls for 15 to 17 minutes or until they are lightly browned. Once baked remove from pan and cool completely on cooling racks

Frosting- While the rolls are cooling make your frosting. Add 1/4 butter to a medium saucepan. Heat over medium heat stirring constantly until the butter is a golden brown. Remove from heat and add powdered sugar and vanilla, mix until combined gradually add the heavy cream until you have the right consistency for spreading. Beat until smooth and spread over sweet rolls.
