Preheat the oven to 350°F and lightly grease a 9x9-inch baking dish.
Whisk the eggs directly in the baking dish, then add the pumpkin puree, maple syrup, almond milk, vanilla extract, and pumpkin pie spice. Whisk until completely smooth and spread into an even layer.
In a medium bowl, mix together the rolled oats, almond flour, coconut sugar, butter (or coconut oil), and cinnamon with a fork or your fingers until crumbly.
Sprinkle the crisp topping evenly over the pumpkin filling.
Bake for 30–35 minutes, until the topping is golden and the filling is set with a slight jiggle in the center.
Let cool for at least 15 minutes before serving. Enjoy warm with ice cream or whipped cream!
