I took some decorating classes from a friend while we were in the Navy in the 1970’s and I’ve been decorating cakes ever since. My 3 grandsons always choose what kind of kids birthday cake they want for their birthdays.

My 4 year old wanted Scooby-Doo. I used a lot of fondant or royal icing to make things that I feel would be a little hard for me to do and with fondant you can add dimension to the features. Fondant can be bought in a package at the store.

I took the invitation and enlarged the Scooby picture to the size I wanted and made a number of copies. I cut out the entire thing and then cut out individual pieces that I wanted to make features. The fondant was colored by kneading in the color paste and rolled out. I used a knife to cut the forms.

The nose, cheeks, lips, eyebrows eyes etc. were made thicker to stand out. It’s like playing with Play Dough! I put them in a covered container until ready to put on the cake. The cake decorating on this cake is the simple part.

I ordered a set of pans with a round top. This one is a 14” round. I really like using these pans that require only a bottom border. After icing the cake I needed only one large round tip with two colors for the border and another smaller round tip for the name. Scooby went on top. I outlined Scooby with a small open tip in black and added some finishing touches and it was finished.

It was a really cute kids birthday cake. I like Duncan Hines cake mixes the best. I have a whipped cream icing recipe that I have always used. It stays soft all the time.

I took a coloring sheet that I got online and blew it up to fit the kids birthday cake. Take the coloring sheet and stick to a flat surface like a cookie sheet, then put saran wrap over the top of that. Trace the outline of Scooby and freeze it; then fill it in. Ice your cake and then freeze that as well.

Flip your filled in Scooby-Doo onto the frozen cake and undo the saran wrap from the flat surface place cake back in the freezer before removing the saran wrap. Once both are frozen again the saran wrap should come off fairly easy. Then you just have to do your piping around the edges.

I made this kids birthday cake by first tracing (with a black marker) a picture of Scooby and shaggy onto a piece of waxed paper. Then I turned the waxed paper over and traced the image with a blue edible cake gel.

When that was finished, I placed the waxed paper (gel side down) onto my un-iced cake. I rubbed in the gel, and then pulled off the waxed paper. It gave me a general outline of the image, but I still needed to keep the original picture, because the gel image sometimes blurs the fine details, so I needed the picture for reference.

Then I filled in the image with the proper coloured icing. There was a lot of detail, so it took a couple of hours to finish, but the kids just loved it!!

I have been baking cakes and practicing with decorating for my kids’ birthdays. One of my daughter’s co-workers asked if she knew anyone who makes good tasting cakes and could put Scooby Doo on it and she said, “my mom can do it!”

I found a photo of Scooby online and, using a toothpick, “sketched” it to the top of the kids birthday cake. He is filled in with tiny stars. The brown color was obtained by mixing cocoa in with some white icing. It was much easier than I thought it would be and Aiden loved it!!

This is chocolate cake iced in white buttercream. Image is from internet (I found it using Google images for “Scooby coloring page”), blown up on a photocopier. I then traced onto wax paper using a sharpie pen, after which I re-traced using black piping gel and then transferred onto cake (after icing had set).

After that, I used no. 3 tip to outline everything in black, then piped in tip 16 stars. I added edible confetti and Smarties candies for border decorations.

For this kids birthday cake, I baked a 9×12 cake and trimmed the left top side diagonally for the windshield, and then about an inch off the bottom to form the wheels. I covered it all with a thin layer of frosting and then colored the frosting.

I got a tube of black and another tube of orange frosting for the decoration. We served the cake and ice cream in dog dishes that I got from the dollar store. We washed and sent them home with each child that attended.

For this Scooby Doo kids birthday cake, I bought the Scooby Doo cake pan and made the cake. I then decorated it with brown, light turquoise, red, yellow, green, white, and black buttercream icing. It was so fun to decorate.

This kids birthday cake was done with the Wilton Scooby Doo character pan. Scooby’s coat was done in a rich chocolate buttercream icing. This is a very easy and wonderful looking cake.

TIP: Cover your heavy cake board in aluminum foil, and then with a colored plastic wrap. We used crystal blue plastic wrap. It went well with the teal colored lines in the collar. Enjoy!!

My daughter’s birthday falls in the middle of October. She was going to be Daphne from Scooby-Doo for Halloween, so she wanted a Scooby-Doo Halloween party. I purchased the characters at Target.

The Scooby Doo kids birthday cake was made using a 9×13-inch pan. After frosting the base of the cake, I added orange and black sprinkles to add a little more color to the sides of the kids birthday cake.

Pretzels dipped in white chocolate made up the picket fence and gate. A path of marshmallows leads up to the haunted house. Trees were made from chocolate Twizzlers, cut at the top to look like branches. I stuck wooden skewers in them to hold them upright.

The headstones are just cookies covered in white chocolate. The ghosts and bats are plastic picks I found at the grocery store in the Halloween aisle. I made jack-o-lanterns out of extra thick frosting and used them to hold the candles.

The haunted house is made out of a box. I “glued” down graham crackers to the sides using frosting and then frosted them purple. Windows we created using different colored frosting. The roof has crushed Oreo cookies for its shingles. Coming out of the roof is a bat pick and a moon made from a wafer cookie, dipped in white chocolate.

I wanted to reserve as much of the cake top for the characters and everything I had planned to go on the kids birthday cake, so I chose to set the haunted house off to the side as its own element. It also helped when it came time to cut the kids birthday cake that I didn’t have to remove it. We were able to keep the haunted house out as a decoration for Halloween.

To make this Scooby Doo kids birthday cake I used 2, 9×13 layer cakes and stacked them on top of each other. For this actual kids birthday cake I separated the French vanilla cake mix into two bowls and added food coloring to change the vanilla color into a teal and purple to marble them into a “Scooby” colored cake.

I bought a chocolate mold for the haunted house and prepared that ahead of time. I found headstone candles for the graveyard, and the skeletons where pushed down into the cake to look as if they were climbing out to get Scooby.

I used coconut and spray food coloring to try and make the coconut look like long, dead grass in an old spooky graveyard. The Scooby sprinkles I purchased at a cake decorating store.
