With cinnamon, nutmeg, and real pumpkin puree, these Pumpkin Waffles bake up light and fluffy inside with a crisp finish—great with butter or a drizzle of maple syrup.
In a medium-sized bowl, whisk together the flour, cornstarch, baking powder, baking soda, salt, cinnamon, and pumpkin pie spice. Set aside.
In a large microwave-safe bowl, melt the butter. Whisk in the sugar, then the pumpkin puree, followed by the buttermilk (this will help prevent curdling). Add the vanilla and egg yolk, and whisk to combine.
In a medium bowl with a hand mixer, or in the bowl of a stand mixer, whip the three egg whites until stiff.
Fold the dry ingredients into the wet ingredients just until a few streaks remain. Add the egg whites and fold just until incorporated. Do not overmix.
Scoop the waffle batter into the hot waffle maker and cook until crisp. Serve immediately or toast to reheat.
Notes
STORE Pumpkin Pie Spice Waffles once they’ve cooled completely. Stack them with parchment paper between each layer and place them in an airtight container or zip-top bag in the fridge. They’ll stay good for a few days.To FREEZE, line a baking sheet with parchment paper and arrange the waffles in a single layer. Freeze until firm, then transfer to a freezer-safe bag. They’ll keep well for up to 1 month. To REHEAT, use a toaster or toaster oven until warm and crisp again. Avoid microwaving if you want to keep the texture nice and crisp.
