In a medium mixing bowl, combine the flour, baking powder, salt, and baking soda. Set aside.
2 cups all-purpose flour, ½ teaspoon baking powder, ½ teaspoon fine grain salt, 1/8 teaspoon baking soda
In a large mixing bowl, beat together the butter, brown sugar, and granulated sugar until light and fluffy. Add the egg and vanilla and beat until well blended.
10 tablespoons unsalted butter, ½ cup light brown sugar, ¼ cup granulated sugar, 1 egg, 1 teaspoon vanilla extract
Gradually add the flour mixture and cocoa powder. Beat to form a smooth dough.
2 tablespoons unsweetened cocoa powder
Roll a tablespoon-sized ball of dough, and place it on a parchment paper lined baking sheet.
Arrange eight pretzel sticks around the ball like spokes on a wheel. Break the pretzel sticks in half if they are long.
1 bag thin, short pretzel sticks
Press the tips of the pretzel sticks firmly into the dough ball. Continue with the rest of the pretzels and dough.
Bake until the cookies start to brown around the edges, about 7-10 minutes.
Remove from the oven. Place the baking sheet on a wire cooling rack, and let the cookies cool on the baking sheet for about 5 minutes.
Lift the cookies from the baking sheets with a spatula, and place directly on wire cooling racks. Let cool completely. Place the racks on sheets of parchment paper, aluminum foil, or waxed paper.
In a double boiler (or the microwave), melt the chocolate chips with vegetable oil.
Turn a spider upside down, and dip into the melted chocolate. Shake a little to remove excess chocolate. Place on the wire rack and continue dipping cookies. Spread any missed spots with the tip of your finger.
Sprinkle with chocolate sprinkles to coat.
