So let's get our geek on and make a gingerbread Menger sponge.
Step 1: Menger sponge
In the next iteration, you look at the smaller subcubes of the original cube and repeat the same process.
in the picture below you can see the same process. With this gingerbread fractal we'll be making a level 2 Menger sponge and using decoration to make it look like a level 3.
Don't worry if that doesn't make sense, we'll move out of math geek territory now.
Step 2: Make some gingerbread dough
7 cups all-purpose flour
1 1/2 teaspoons salt
1 teaspoon baking soda
1/2 teaspoon baking powder
1 1/2 cups solid vegetable shortening or unsalted butter
1 cup (packed) brown sugar
2 large eggs
1 1/2 cups molasses
Whisk together the flour, baking soda, salt and baking powder.
Beat the shortening or butter at medium speed until it's light and fluffy. Add the brown sugar and beat to blend. Beat in the eggs one by one, and then beat in the molasses. Reduce the mixer speed to low and gradually stir in the flour mixture.
Divide the dough in thirds, wrap in plastic and chill for 3 hours.
