1
Make the cupcakes.
-
2
Position a rack in the middle of the oven.
-
3
Preheat the oven to 325F.
-
4
Line 12 muffin tin cups with paper cupcake liners.
-
5
Sift the flour, baking powder, baking soda, salt, cinnamon, and ginger into a medium bowl and set aside.
-
6
In a large bowl, using an electric mixer on low-medium speed, beat the melted butter, sugar, and pumpkin until smoothly blended.
-
7
Mix in the eggs and crystallized ginger.
-
8
On low speed, mix in the flour mixture until it is incorporated.
-
9
The batter will be thick.
-
10
Fill each paper liner with a generous 1/4 cup of batter, to about 1/2 inch below the top of the liner.
-
11
Bake just until the tops feel firm and a toothpick inserted in the center comes out clean, about 25 minutes.
-
12
Cool the cupcakes for 10 minutes in the pan on a wire rack.
-
13
Carefully place the wire rack on top of the cupcakes in their pan.
-
14
Protecting your hands with pot holders and holding the pan and rack together, invert them to release the cupcakes onto the wire rack.
-
15
Turn the cupcakes top side up to cool completely.
-
16
Frost the cupcakes.
-
17
Transfer 1/4 cup of the frosting to a small bowl, and stir in enough cinnamon to make the frosting a light brown color and enough milk to make a thick but pourable frosting.
-
18
Set aside to use for the spiderweb decoration.
-
19
Use a small spatula to spread a scant 1/4 cup of the remaining frosting on top of each cupcake in a smooth even layer.
-
20
Cleaning the spatula often against the side of the bowl will help you spread the frosting smoothly.
-
21
Spoon the reserved cinnamon frosting into a small self-sealing freezer bag.
-
22
Press out the excess air and seal the bag.
-
23
Cut a tiny hole in one corner of the bag, about 1/16 inch long.
-
24
Hold the bag about 1/2 inch above a cupcake and slowly pipe 2 circles, one inside the other, on the frosting.
-
25
Pipe a dot of the frosting in the center.
-
26
Using a toothpick, and beginning at the center, draw the tip gently through the frosting toward the edge of the cupcake.
-
27
Move the toothpick about 3/4 inch away and, beginning at the edge of the cupcake, draw it toward the center.
-
28
Continue pulling shallow lines, alternating the direction of the toothpick, around the top of the cupcake, to form a web pattern.
-
29
Repeat with the remaining cupcakes.
-

The cupcakes can be loosely covered and stored at room temperature for up to 3 days.
