Any Big Mac fan is going to love this Big Mac cake! It's perfect for a birthday, Father's Day celebration, or just for fun! Yellow cake, brownies and frosting make this burger cake.
Put everything, except the vanilla, into a medium bowl. Place the bowl over a pot of simmering water to make a double boiler. Do not let the bowl touch the water. Place a spatula into the pot to allow the steam to escape.
Cook mixture over medium-low heat and beat with a hand mixer on medium high speed. It should take seven minutes to achieve stiff peaks.
Remove from heat and beat in vanilla. Separate into three bowls with food coloring. Whip in the colors being careful not to over whip the frosting. It will turn to liquid and loose all the air bubbles if you over whip.
Frost immediately or cover with plastic wrap pressing onto the frosting to avoid drying out.
For the cake construction
Level one cake layer and place on a serving tray. Whe the edges of the yellow cake are a bit browner than desired, trim them. Place a round fudgy brownie layer on top.
Add some Orange (special sauce), Green (lettuce), and Yellow (cheese) allowing some to drip over the edges.
Level a second yellow cake and repeat with the brownies and frosting as decribed above.
Top with remaining yellow cake and sprinkle on some sesame seeds.
Notes
This cake can be made all in one day. Simply buy the foil round pans and bake everything in one day. Save the egg whites from the Yellow Cake to make your frosting.
