I made this cake for my boss. My boss loves chemistry and scientific things therefore had to come up with some fun cake designs. Someone at the office came up with the idea to make the Simpson's nuclear power plant. A Homer Simpson figurine would have definitely been a nice touch but I was unable to find one.
The smoke towers are made from two ice cream cones turned upside down and wrapped in gray colored fondant. The smoke is just fondant rolled into balls (mini marshmallows can also be used). The other buildings are just different cookies and sugar wafers. I used yellow Twizzlers to make the parking stumps for the parking lot. Two boxes of cake mix were used in a sheet cake pan (chocolate on one side and yellow on the other). The trees were made with pretzel rods and green colored fondant on the top.
Good luck with your own fun cake designs!

For my son's Mad Scientist Party we created this test tube cake made from two rectangular cakes. There is no end to fun cake designs when having a scientist party. This was made on a board with a slit in it then covered in aluminum foil. We then set the board on a 13x9 cake pan which had dry ice and warm water. The special effect of steam bubbling out of the top was the most fun for the kids!

My son was having a Mad Science Birthday party and I wanted to make funs cake designs that really went along with the theme. I started by baking two 14" wide 3" deep round layers of red velvet cake. After cooling I leveled them and put them together with a layer of the lime green icing I chose for the cake. Then frost the rest of the cake.
| The Brain: I found a brain jelly mold online. You can make the brain jelly with peach jelly and you use 1 cup of boiling water and 1/2 cup nonfat condensed milk to make the jelly. Then you have to add a few drops of blue, red and yellow food coloring to get the right shade of gray. It is important to start out with light jelly (peach or champagne...something like that). | ![]() |
I tried out the brain thing before doing the cake to make sure I could get it right. I would advise anyone to do that. After the jelly was the right color gray I poured it into a lightly greased mold (use cooking spray and then wipe out excess with a paper towel). Chill until set. Gently turn the jelly out onto a large plate. If it won't come out you may need to fill the sink with warm water and hold the jelly mold in the water for a few seconds being careful not to get water into the mold or jelly.
Then I took a fine paint brush and brushed veins onto the brain using Wilton paste in NO Taste Red. The candles are wrapped in beading wire from the craft department to look like electrodes. It is just a spiral. Then I cut 2 lengths of new air hose from a fish tank aerator and spiraled more craft wire around them. In between I made the wire spell out "Happy Birthday" in cursive letters...this doesn't show up very well in the picture but it looked very cool in person. The hardest part was moving the jelly-brain from the plate to the top of the cake. I had my husband hold the plate at an angle over the cake and then I very carefully and quickly made the transfer using a very wide spatula and my hand. I then used a star tip & purple icing to pipe a simple border around the brain & the edges of the cake. Lastly I placed the "Happy Birthday" electrodes over top of the brain & the candles in front.
This was one of the most successful and fun cakes designs I ever made. The kids were crazy over it. They were daring each other to eat a slice of the brain and they let out a chorus of gasps when I cut the cake and they saw the bright red cake against the lime green icing. A huge success!

This beaker cake was made for my husband's 28th birthday (he's a bit of a science nerd!).
I started by baking a chocolate cake in a rectangle pan. I cut the beaker shape free form and iced the entire cake with white buttercream. I slightly heated green buttercream to make it more fluid and poured it over the bottom part of the cake and added the drops up the neck of the beaker.
I used Wilton ready-to-use gel in black to outline and add graduations. I also put 28mL on the beaker because it was his 28th birthday. I added all of the candles at the top so that, when lit, it looked like the formula was aflame!
