Cake Postcards!

 
Materials needed to make two cake postcards:

• 1 large sponge (yellow paints the best)
• Serrated knife
• X-Acto or utility knife
• Spray paint (brown, yellow, pink or white)
• 1 tube acrylic latex caulk (brown, cream or white)
• Spray adhesive (3M Super 77 works great!)
• Cardboard, kraft paper or scrapbook paper

Step 1: Cut sponge into wedge shape.

  
Step 2: Cut a center groove into sponge.


Step 3: Paint the sponge.


Step 4: Trace the slice of cake.


Step 5: Attach the card.















Step 6: Prep the "icing"

Using a caulking gun and your desired caulk, fill a plastic disposable piping bag with half of the caulk. This should be enough to do one cake wedge. I was able to pipe two cake postcards with one tube of caulk, but I recommend putting only half of the caulk in the bag at a time. Also, I tried decorating my cake wedges using the caulking gun, but it was nearly impossible to control. It's much easier with a piping bag.
 

Step 7: Pipe the center of the cake.


Step 8: Pipe the icing on the top and side.


Step 9: Add the swirls.


Allow your cake cards to dry for three to five days. I placed mine on sheet of parchment paper and lifted them up periodically so that the caulk wouldn't dry and adhere to the paper.
