In a large bowl combine the flour, sugar, baking powder, and baking soda. Add egg, buttermilk, pumpkin, and melted butter; whisk to combine.
Heat a nonstick skillet over medium-high heat. Add 1 teaspoon unsalted butter; swirl pan to coat.
Spoon heaping tablespoons of batter 2 inches apart into skillet.
Cook for 1 to 2 minutes or until pancakes have bubbles on top and are slightly dry around edges; turn.
Cook until golden on bottom, about 1 minute more. If pancakes brown too quickly, reduce heat to medium.
Repeat with remaining batter and unsalted butter.
Serve warm with syrup and raspberries.
