Giant Doughnut Cake (Or How To Make Your Own Cake Molds)

Featured
My roommate loves doughnuts, so I decided to make her the biggest one she had ever had. They sell doughnut cake molds, but I was on a budget and didn't know when I'd ever make another one, so I opted to make my own mold and here's the result!

I ended up making a two layer cake, but you can make a slightly smaller, single layer cake.

The ingredients for 2(or 1) boxes of cake mix (oil, water, eggs, etc . . .)

Icing
1/4 cup milk (I used skim because it was all I had, but you're supposed to use Whole. The choice is yours)
2 cups confectioner's sugar
1 tsp vanilla extract (Optional)

Chocolate Frosting
1 lb confectioner's sugar
1/2 cup butter, melted
1/2 cup cocoa powder

Step 2: Making a model for your cake mold

Take a pair of pajama pants and close the end of one leg with string or fishing line. Next, fill same leg with other laundry till it is stuffed, but flexible. Then, curve leg into a circle and wrap the remaining leg around the end of the stuffed leg so that you get a large doughnuts shape. This doesn't need to be perfect. I know you're all very creative people, so if you can think of a more practical way to make a doughnut shape, more power to you.

I like the idea, but have to say I would go with a vacuum table and multiple layers of foil to make the pan. Multiple layers of foil under a thin piece of plastic - possibly may have to do it several time depending if individual layers rip while forming the shape.

But that is me - I see from past posts I have turned into a vacuum freak. Lol
