Stir the flour, baking soda, baking powder, salt, cinnamon, and pumpkin pie spice together in a large bowl until combined.
In a medium bowl, whisk the pumpkin, brown sugar, butter, maple syrup, and buttermilk together until combined. Pour the wet ingredients into the dry ingredients and stir until homogeneous. Try not to overmix the batter.
Pour the batter into the cake pan and spread the praline topping evenly on top. Gently press any crumbs into the batter.
Bake the cake for 30 minutes. To check if the cake is done, insert a toothpick. If the toothpick is clean, the cake is done, if the toothpick has wet batter on it, bake for 2 minute intervals until the toothpick is clean.
Serve the cake warm or at room temperature. Enjoy!
