Coolest Bob the Builder Cakes on the Web's Largest Homemade Birthday Cake Gallery

I made Bob the Builder for my son Kaden’s second birthday. He is a big fan of Bob the Builder.

I used store bought cake mixes to bake the cake and frosted it first with a buttercream. I then colored the rolled fondant and covered the cake. I used black licorice for bob’s eyes and used a toy screwdriver and hammer to add some 3 dimension effects.

The watch on Bob’s hand was actually put to cover a mistake as the fondant had started to crack slightly. Everyone thought the watch looked cool.

To see my son’s eyes light up when I brought out Bob the builder was worth every minute it took to decorate it!

I used the Bob the Builder Wilton cake pan. I mixed a White cake mix for the cake.

For the icing: 1 1/2 cup Crisco, 1/2 cup water, 2 lb powdered sugar, 1/2 tsp. salt, 1 tsp. vanilla and 1/2 tsp. buttercream flavor. Cream together Crisco, salt, vanilla butter cream flavor and half of your water. Blend until incorporated. Add remaining sugar and water. Use Wilton gel colors.

This is the Bob the Builder cake I made for our son’s recently celebrated 4th Birthday.

The cake was baked in Wilton’s 1/2 sheet pan. I also use Wilton’s recipe for icing when decorating. I iced the sides with white decorator icing and then began work on the top of the cake. The grass was created using Wilton tip #233. I tinted the remaining green icing a darker green and trimmed around the base of the cake.

I used brown coloring to create my road and then using chocolate covered graham cracker cookies “paved” a portion of the road and covered the remaining portion with crushed Oreo cookies.

I frosted a cupcake with the brown icing and placed it upside down on the cake.

I then covered it with additional crushed Oreo’s.

I found “Bob the Builder” on eBay and purchased “Scoop” and “Roley” at our local Target. “Bob the Builder” is holding a ‘caution’ sign that came with mini-construction vehicles that we already had. Alex loved his cake and had fun “digging” in the dirt and “paving” the road once the candles were blown out.

Use the Bob the Builder pan and decorate as per the instructions. I made the smaller cake using a half moon mold. I used one cake recipe for the Bob cake and about 2/3 of one cake recipe for the half moon. It’s frosted with buttercream frosting.

This Bob the builder cake was made for my friend’s son for his 2nd birthday. I couldn’t find many pictures of bob the builder (which was odd), so I used this image that I had seen used for a lot of cakes (I think its the Wilton pan shape too). I created this picture freehand and I was very pleased with how well it turned out. Again for all of my cakes, it was buttercream icing.

This Bob the Builder Cake was my Sons 4th birthday cake. He loved Bob the builder so I decided to use it as the theme for his party and started thinking of cake ideas.

First I used a large 12×17 pan (with 2.5 cake mixes). Then I cut the cake and joined it together to look like a triangle – or a Yield sign. I then drew pictures (or you can use coloring book pages) of each vehicle and traced it onto the already frosted cake with a toothpick. I then outlined them with black icing and filled in all the colors.

The lower portion of the cake was bare so I decided to draw a hammer to tie in with the theme. My son and all his friends thought that this was one of the coolest cake ideas.

My Son’s favorite TV show was the Bob the Builder so when his second birthday came around we had a “Can We Fix It” theme party. The Cake was made in my largest cake pan (9 x 13), the print of Bob I had gotten off the internet, I blow up the picture, pressed it onto the cake after it had cooled and cut off the extra cake to make the figure. Once I was done with the cutting I removed the printed picture from the cake and used that to copy the design from. I found it easier to bake the cake the day before and let it cool in the fridge overnight before cutting and decorating.

Items used for this Bob the Builder cake:

  • 2 cake mixes
  • 3 cans white frosting
  • 1 large rectangle cake pan
  • 2 boxes of Smarties
  • Blue and green food coloring
  • Oreo baking crumbs
  • 2 miniature Bob the builder construction figurines
  • Bob the builder candle set
  • 10 pretzel sticks

Bake the cake mixes according to directions and let cool. I usually freeze the cake to make decorating a little easier. Tint 2 1/2 cans of frosting green for grass and ice entire cake. Place Smarties in a road shape diagonally. Use pretzel sticks to form road blocks and between road blocks place a pile of crumbs to look like a dirt pile. Place your figurines near the pile of dirt with Bob the builder and candle. In one corner of my cake I made a pond shape lined with Smarties using the blue tinted icing.

My little boy wanted a Bob the Builder cake. I just used some of his little figurines and for the road I used chocolate-covered Keebler graham cookies. I dug a little of the cake out to make it look like the backhoe was digging.

My son wanted Bob the Builder cake for his 4th birthday. He wanted me to make a dump truck and being rather novice, I knew that it would be hard to do. I decided to use a plastic dump truck that he could keep and I filled it with dirt (made from brownie mix pudding, cookie crumbs, and the hit of the party gummy worms). Next time I would use more worms.

I used a shovel to serve and place the Bob the Builder figure on top of the truck. The work site I made using a square pan and grass tip to frost, I used graham cracker crumbs crushed to make the road in the middle. The workers and construction cone candles were found at a party supply store.

I used wooden dowels to support the truck and keep it from rolling off the cake. I placed them behind each tire and it worked well. Make sure they are long enough to go at least half way into the cake.

My son had a Bob the Builder party for his 4th birthday. I made a 9X13 inch cake, as directed on box. Any flavor will do.

I colored vanilla store-bought frosting with blue, red, and yellow food coloring until the desired gray shade was achieved. This took a while. (HINT: Use one or two drops at a time, as making up over-coloring with contrasting colors is difficult.)

I crushed Oreos with a Food Chopper and sprinkled on the cake in a “driveway” design, ending in a pile of cookie crumbs, a.k.a. dirt pile (it’s easiest to trace an outline of your driveway on the cake with a toothpick, so you make sure you get the cookie crumbs in the right place).

I found the Bob the Builder characters online. The kids still play with them! I made the “billboard” myself with a “print shop” type of computer program. The sign is two-sided, taped together, with cut-off straws as “poles” to poke into the bob the builder cake. You could also draw, color, paint the sign freehand, if you don’t have the computer software, or are not computer-savvy.

This Bob the builder cake was a double layer cake.

I had a little trouble with the filling. I used a lemon filling, but the icing wouldn’t stick to the sides, so I had to put icing about 1-inch around the diameter of the top of the bottom cake. Then I put the lemon filling on the cake. This stopped the icing from falling off of the sides. I just drew the Bob the builder face on with a toothpick and then filled it in with the proper colored icing.
