Preheat the oven to 175 degrees Celsius (350 degrees Fahrenheit) and lightly grease an 8x8 inch square baking dish.
In a large mixing bowl, whisk the Greek yogurt, eggs, vanilla extract, and almond milk until the mixture is uniform.
Incorporate the vanilla protein powder, rolled oats, baking powder, cinnamon, and salt into the wet ingredients, stirring until just combined.
Fold half of the sliced pears into the batter.
Transfer the batter into the prepared baking dish and spread evenly.
Arrange the remaining pear slices across the top of the batter in an aesthetic pattern.
Place the dish in the oven and bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
Remove from the oven and allow to set for 5 to 10 minutes before portioning into four equal servings.
