Preheat the oven to 350℉ and line an 8x8-inch baking dish with parchment paper.
Add the yogurt, pumpkin puree, brown sugar, eggs, vanilla extract, and pumpkin pie spice into a large bowl and whisk together.
Transfer the yogurt mixture to the baking dish and place in the oven. Bake for 30 minutes. There should still be a slight jiggle in the center of the pie.
Let the baked yogurt cool for 10 minutes.
Serve with granola and a drizzle of maple syrup.
