Place the butter into a medium saucepan over medium heat. Let the butter cook while occasionally stirring to ensure the butter is cooking evenly.
½ cup unsalted butter
Cook the butter until it is a golden brown color and smells nutty and toasted, about 5 -7 minutes. Remove the pan from the heat.
Let the butter cool to room temperature.
Combine the flour, pumpkin spice, baking powder and salt in a medium bowl and whisk to combine.
1 cup all purpose flour, 1 teaspoon pumpkin spice, 1 teaspoon baking powder, ½ teaspoon fine sea salt
In the bowl of a stand mixer, fitted with the whisk attachment, combine the eggs and sugar. Beat on medium speed for 2 minutes until well blended.
2 large eggs, room temperature, ½ cup granulated sugar
Beat in the cooled butter, maple syrup and vanilla extract.
2 tablespoons maple syrup, 2 teaspoons pure vanilla extract
Add the flour mixture, beating on low speed, until just combined.
Add the pumpkin purée, beating until just combined. Do not over mix.
⅓ cup pumpkin purée
Cover the bowl and place in the refrigerator for at least 1-2 hours.
During the last few minutes of chilling, preheat the oven to 350°F (177°C).
Spray the madeleine pan with baking spray.
Use a cookie scoop to place about 2 tablespoons of batter into each mold. Do not over fill. Each mold should be filled about ¾ of the way.
Bake for 9-10 minutes. The madeleines are done when the tops spring back after lightly pressed with your finger, or when a toothpick inserted comes out clean. Invert the pan onto the counter, tapping to release the madeleines. Transfer the madeleines to a wire rack to cool.
While the madeleines cool, melt the chocolate and shortening in a microwave safe bowl in 30 second increments. Stir between each increment until fully melted and smooth.
1 cup semisweet or bittersweet chocolate, 1 teaspoon vegetable shortening
Dipped the cooled madeleines into the chocolate and place on a drying rack.
Before the chocolate sets, sprinkle with chopped pecans. Let the chocolate set, then serve.
¼ cup pecans, finely chopped and toasted
