Diego Cake

A friend of the family was having a Diego party for their son's 3rd birthday, and they asked me if I would make a Go Diego Go cake. Here is what I came up with.

Everything was purchased at either my local grocery store, local candy store, or Michael's. Toys were purchased from Target and Toys 'R' Us.


  • 3 boxes of cake mix (I chose 1 yellow cake and 1 chocolate cake)
  • 9 eggs
  • Vegetable oil
  • Water
  • 2 tubs of buttercream icing
  • Crisco
  • Large pretzel logs
  • Bag of spearmint leaves
  • Grasshopper cookies (100 calorie packs)
  • 1 tub Wilton Decorator icing (stiffer than regular store-bought icing)
  • Green licorice strands
  • Jawbreakers that look like rocks/stones
  • Clear rock candy (on a string)
  • Green rock candy (on a stick)
  • Chocolate melting wafers

Diego Cake Directions:

Step 1: Grease 8x8" and 12x12" cake pans. Layer the bottom in parchment paper cut to the size of the pan. (This helps the cake come out without sticking to the bottom of the pan).

Step 2: Prepare one box of cake mix following instructions on the box (i.e. combining cake mix, 3 eggs, 1/3 cup vegetable oil and 1¼ cup water in a large mixing bowl).

Mix on low for 30 seconds followed by 2 minutes at medium until smooth. Pour it into the 8x8 pan.

Step 3: Prepare the second and the third box of cake mix, and add into the 12x12 pan. A bit may be left over as you don't want to overfill the pan and cause spillage in the oven.

Step 4: Bake the cakes at 325°F for about 35 minutes (consult the cake mix for your specific type of pan and make sure that the cake is done using a toothpick). I baked the 8x8 and the 12x12 together.

Step 5: Allow the cakes to cool slightly, then run a knife around the sides and flip onto a cooling rack. Pull off the parchment paper and flip again.

Once the cakes are significantly cool, take a large knife and level the cakes cutting off the raised centers.

You don't need to be exactly perfect as this cut surface is going to be the bottom of each of the layers, with the nice sharp corners and flat top being the part that was molded by the pan.

Step 6: Flip 10x10 cake onto the large piece of cake cardboard for the final cake to be displayed on. Mine was 13x19. This will be the bottom stabilization for the entire cake building process.

You can add a bit of buttercream icing to the center of the board, which will act as a cement to keep the cake from sliding off at any point.

Step 7: Flip 8x8 onto top of 10x10 and angle toward the back right corner, leaving you enough room to create a road across the lower cake.

Some cake will be hanging off the sides of the 12x12. Cut these parts off to create a smooth outer wall. Remove newly shaped 8x8, and place onto a 8x8 piece of card and cut to fit.

Decorating Diego Cake:

Step 1: Using the brown icing dye, tint the buttercream (about 1-2 tubs) a light brown, and add a crumb coat to all cakes. This locks in the crumbs.

Step 2: Spread a thick layer underneath where your second layer attaches, add cake dowels to keep layers from sinking.

Finally add a nice thick layer of the buttercream on all the sides of both cakes hiding any gaps caused by the card.

Step 3: Cover area for road in brown buttercream and add crushed Grasshopper cookies (Oreos leave white chunks so I avoided them).

Hint: you can line your area with wax paper and then put cakes into fridge to harden the icing. You can pull the wax paper back off with minimal disturbance.

Step 4: Using the blue icing dye, tint the decorator's icing (third of one tub) a dark blue (can leave swirls in it), and thin with a tablespoon of water.

Add a nice thick layer of the buttercream on the top of the 8x8 cake into the shape of a lake or pond.

Try not to make it a circle, but have many curves to it like a real lake. Continue water down side onto 12x12 and then down to mat for your waterfall.

Add Jawbreaker rocks around pond and down waterfall. Crush the clear rock candy and add to areas for 'foam' in the waterfall.

Step 5: Use the remaining decorator's icing and tint bright green to cover the remaining surfaces with grass. This part takes the longest. Green licorice can be added to wall for a jungle feel. Green rock candy on the sticks can be inserted for trees.

Step 6: Additional trees can be made by dipping the pretzel logs in chocolate (refrigerate to harden).

Using lots of granular sugar, roll out the spearmint leaves and use a small cookie cutter to cut leaves out. Use melted chocolate to adhere them to top of coated pretzel logs.

Finally, add toys!
