Preheat the oven to 400 degrees F and grease an 8 x 8-inch baking dish (or spray with nonstick cooking spray).
In a medium bowl, whisk together the flour, baking powder, salt, spices, brown sugar, and cornmeal.
In a small bowl or glass measuring cup, lightly beat the eggs, and then stir in the pumpkin, oil, and molasses.
Stir the wet ingredients into the dry ingredients just until combined, and then pour the batter into the pan, smoothing out the top as much as possible.
Bake 30 minutes or until a knife inserted in the center comes out clean. Serve warm.
