My grandson loves Lego’s, so I surprised him with this Birthday cake.  I found many creative ideas for Lego cakes on http://www.coolest-birthday-cakes.com.

Lego CakeOne clever idea in this website, was to tape bubble wrap to the tray.  Spreading the frosting on the bubble wrap was made easy by thinning a can of white frosting with some milk and green food coloring.  I poured the frosting on and then spread it with a knife.  Removal was done by kids licking fingers.

I baked two Betty Crocker chocolate cakes (his favorite) in 9 x 13 size pans. The cooled cakes were cut into thirds and then into halves for different sizes. The ½ sizes can be cut in ½ again for the very smallest size.  Each Lego is 2 layers high for the largest sizes.  Note: This is where I had a problem with the moist cakes becoming sagging Legos.  I’ve since learned to wrap tin foil around carboard pieces and insert them between the layers to stabilize the leaning tower look.

I froze the cake pieces, so the cut edges frosted easily with less crumbling (a professional cake baker tip).  I then cut large marshmallows in half and frosted them for the Lego tops (another neat idea from the website).  Although fondant icing would give a finished look and frosting the sides smooth took longer, the taste was worth it.

The little Lego guy is made from Rice Krispie treats. The bars mold easily and stick together perfectly.  I cut ½-bar for the body and ½-bar to make the two legs.  Another bar was cut up to shape a round head, two arms and feet.  I used colored fondant to cover him and Wilton FoodWriter pens to draw fine lines for the eyes and other details.

Please let me know if you have any questions for creating this fun cake.

  17. That is a really cool idea I would have never thought to use bubble wrap.

    • I’m can’t take credit for the idea. I found a site that used bubble wrap and it really looked like the Lego base.
