Hot and oozing, sweet apple with crunchy oats and nuts, served with whipped cream. This dessert is fantastic any day of the week, and you likely have the ingredients for it on hand.
Preheat your grill to medium–high.
Wash, then very carefully core your apples without chopping them in half. If you have a stubborn core, use a grapefruit spoon, or strawberry hull-er to scoop out the unwanted parts. Be careful not to come out the bottom end of your apple. Create a hollow area in the middle of the apple while you are scooping it out. Dribble a little of the lemon juice inside the hollowed out apples, turning them so that the juice coats the inside. This prevents them from going brown.
Combine the brown sugar, oats, cinnamon, raisins, and nuts. Add the butter, using a pastry knife or fork to mash the butter until all of the oat mixture is sticking together in clumps. At this point you may need more butter if there are still dry ingredients not clumping.
Stuff each apple with the butter and oat mixture as full as you can.
Place the planks on the grill, then place the apples on your presoaked planks. Close the lid and grill-bake for 20 to 45 minutes, depending on the apples you have chosen. You will want the apple flesh to still have a little solidity to it, not be mushy and collapse under itself. When it yields to a fork, you know it is done.
Remove baked apples from the grill and serve with whipped cream or a la mode.
We had these last night, when my husband was craving a sweet treat. They were really good, but I do not recommend using cortland apples for this, they were a little watery flavored.
