Preheat the oven to 350 degrees.

Process the pears until they are applesauce consistency.

Pulse in the applesauce, lemon juice, cinnamon, baking powder, and salt.

Add in the oats and process until everything is well combined.

Meanwhile, heat the blueberries with three tablespoons of apple juice until boiling.

Lower the heat to a simmer, and cook five minutes, stirring a few times during the process.

In a small bowl, mix the arrowroot with the remaining tablespoon of apple juice.

Pour the arrowroot mix into the hot blueberries, stirring frequently.

Stir in the vanilla and remove the pan from the heat, continuing to stir until thick.

Lightly oil an 8 x 8 baking dish.

Spread about half of the batter into the bottom of the dish.

Top with the blueberry mixture.

Dollop the remaining half of the oat batter on top, similar to how you would dollop biscuit dough for chicken and dumplings.

Bake 25-30 minutes.

Cool, cut, and enjoy!
