Mystery Machine Cake Tutorial

This is the most fun cake that I've made so far. My sister and I love Scooby Doo. We grew up on it and other old cartoons thanks to our dad. So for her birthday she had requested a cake featuring the Scooby gang. And a surprise guest too of course! So here is a scooby doo mystery machine cake tutorial for you all!

Fondant or not to fondant?

Personally I think this scooby doo mystery machine cake would've been 100% better if it had been decorated with just fondant. But my sister hates fondant. And since it's her birthday cake I couldn't use it to decorate the cake. Well except for the two small pieces that I painted the gang and Mr. Hyde on. Thankfully she lived with it after complaining for a few minutes. The chocolate did come out very well though after a few trial and errors. It's definitely not the best looking cake, but it is the most fun. It being Scooby Doo makes it even better.

Make it extra!

I made this cake into a pinata cake and filled it with a bunch of sprinkles and some chocolate chips too. But I think it would be even more fun if it had had some of those graham cracker Scooby snacks and fruit snacks too! Make it completely a Scooby Doo theme I think! Or you could go for the glutenous ways of Scooby and Shaggy and filled it with fun food shaped gummy candy. Little pizzas and ice cream cones would have been a hoot in this mystery machine cake!

Stencil

Use these stencils  to accurately carve out the mystery machine into the correct shape. I also included stencils to draw out the gang and Mr. Hyde as well if you want to make it look exactly like I made the cake. This is completely optional though! The stencils also include notes on what each stencil is used for and how to use them.

leanr how to make a fun scooby doo mystery machine cake featuring the gang and mr. hyde!

• candy melts (light blue, green, white, black, and orange)
• 4 layers cake (use a 9 x 13 inch cake pan. any flavor)
• 1 batch vanilla frosting (tinted light blue)
• white fondant (optional)

cake filling ideas

• candy
• scooby snacks graham crackers
• scooby doo fruit snacks
• sprinkles
• candy

1. once the cakes are cooled, start by filling and stacking the first 3 layers of cake. in the center, cut out a decent sized whole. fill this whole with whatever you like, or use some of my ideas!
2. place the last layer of cake on top and do a crumb coat. place the cake into the fridge for about 30 minutes to chill.
3. use the stencils i've provided to cut the cake to be the exact shape. i used some pins to help keep the stencils in place while i trimmed. if you make a mistake, just use the cake trimmings mixed with frosting (like making a cakepop) and form it into the shape you want.
4. once the cake is formed, do another crumb coat and place the cake into the fridge to chill.
5. while the cake is chilling, use the other stencils and the candy melts to trace the mystery machine designs to put onto the cake. let dry
6. while the chocolate is drying, take the cake and do a final thick coat of frosting on the cake.
7. carefully peel the chocolate designs off the wax paper and place onto the designated areas of the cake.
8. if you have the artistic ability or a projector then paint the scooby gang on some fondant. do the same thing for the back of the cake with mr. hyde.
9. eat and enjoy!
