Cake: Beat the shortening with the sugar. Add one egg at a time; make sure to mix well between each egg. Mix with flour, cocoa, and vanilla extract. Add the hot water and mix well. Pour into 2 10-inch Dutch ovens that have been greased and dusted with cocoa. Cook for about 30 minutes with 12 coals on top and 8 coals on the bottom until toothpick comes out with just a few moist crumbs on it. Do not over-bake. Cool the cakes and cut each in half, horizontally.
Topping: Combine ingredients and mash with a potato masher or fork to release the juice of the strawberries. The ultra gel should make it thicken instantly.
Combine the filling ingredients and mix well with a whisk or spoon, spread the filling between each of the four cake layers. Combine the icing ingredients and mix well with a whisk or spoon, cover the cake with the icing and top with the remaining strawberry topping. Enjoy!
