For the Cake
Preheat oven to 350°F (175°C).
Line a sheet cake pan with parchment, butter and flour it.
Sift and whisk together dry ingredients (including sugar) in a stand mixer bowl.
In a separate bowl, whisk together wet ingredients.
Add wet ingredients to the dry, then mix on medium speed for 2 minutes.
Pour batter into the prepared pan and bake for about 50 minutes, or until a toothpick comes out clean.
Let cool, then invert onto wire racks to cool fully.
For the Frosting
Beat butter in a stand mixer; add cocoa powder on low speed.
Add confectioners’ sugar and salt, mixing slowly.
Gradually add fudge until smooth and incorporated.
For the Assembly
Scoop buttercream onto the cake and spread evenly with an offset spatula.
Drizzle a white chocolate spiral on top.
Use a toothpick to drag from the center outward to create a web effect.
For the Spider
Melt semi-sweet chocolate and transfer to a piping bag.
Pipe “L”-shaped legs onto parchment paper, freeze for 5-10 minutes to set.
Use a brown peanut M&M for the body and a regular brown M&M for the head.
Attach the chocolate legs around the M&M body.
