Preheat your oven to 350°F (175°C) and lightly grease a small oven-safe baking dish with a touch of coconut oil.
In a medium mixing bowl, combine the mashed Kent pumpkin, Greek yogurt, eggs, stevia, and vanilla extract, whisking until the mixture is completely smooth.
Add the oat flour, sea salt, and ground cinnamon to the wet ingredients, stirring gently until just combined.
Pour the batter into the prepared baking dish and spread it into an even layer.
Warm the peanut butter slightly so it is pourable, then drizzle it over the top of the batter and use a knife to swirl it through.
Sprinkle the shredded coconut evenly over the surface.
Bake for 25 to 30 minutes, or until the center is set and the edges are slightly golden.
Allow the bake to cool for at least 10 minutes before serving to let the flavors meld and the texture firm up.
