I will focus on some of the decorations next, but if you want to go ahead and prepare some cakes to decorate :

Make your cakes in 2 - 9" pans and let cool completely. Release from pans.

To make Butter cream icing:

-Mix the shortening and butter until fluffy (can take up to 7 minutes) with a whisk attachment.
-Mix in the vanilla, milk, salt and corn syrup.
-Add 1/2 of your powdered sugar and mix in, then add the other half and then mix until fluffy ( about 5-6 min)

Put one cake on a cardboard cake circle,

carefully cut top level with a serrated knife.

Apply a generous amount of icing on top of that layer and level out.

Add the second layer.

Coat entire cake with icing.

Refrigerate until set then add one more layer of icing covering the whole cake.

Step 3: Flames

Prepare for every part of this step because you will have to work fast. Be cautious!!!
Lay out a large silicone mat nearby.

slowly heat up:
1/4 cup sugar
1 1/2 tablespoons of corn syrup
2 tablespoons of water
Then slowly bring to boil on high until it reaches 300* F or hard crack. (You should see the your mixture turning crystal clear).

Tip: Make sure it is exactly 300 degrees and then remove from heat.
Immediately, add 2 drops of yellow food coloring and stir. With a tablespoon carefully drizzle the yellow melted sugar on the silicone mat in a straight line. Set down your pan safely. With the remaining mix a drop of red and stir. Then spoon some of the orange melted sugar along the same line as the yellow. Carefully take a toothpick and blend colors to look like flames.

Let cool completely.

Step 4: Let's Make a DeLorean

The base is just rice crispy treats molded into a car shape.

Roll out some shape and maze and cover the car. Trim off excess.

Make your stripes for the sides of the car and bumpers in white shape-n-amaze.

Spray the whole car with silver color spray.

Step 5: DeLorean Cont'd

Roll out black shape-n-amaze and cut out the front and side windows for the car.

Make four balls the same size in black and smooth down. to make tires. Make 4 of the same in white for hubcaps. Make black cables and run them over the front wheels of the car.

For the wires in the back use tiny rolls of fondant and color them in with the food markers in various colors.

Color in headlights on white fondant and color in with orange and yellow then use black marker to draw a cross hatch pattern. Cut out and apply to the back of the car.

Apply the hubcaps to the wheels and set in place with toothpicks.

Step 6: Other Details

Make a date counter

Break off a section of a Hershey's bar and trace a piece the same size out of black shape-n-amaze. Apply water on the back of the black section and apply to chocolate bar.

Trace the same shape on white piece and draw out squares where your numbers will be then fill in around them with a black food marker.

Cut around the date in a rectangle. "Glue" onto the flat black part with water.

Step 7: Finish

Place your car, flames and chocolate timer on top of the cake.

Add some finishing touches such as piping some icing along the top edge of the cake and adding some blue color mist at the bottom of the cake.

Display and enjoy your back to the future cake!
