Yellow cake and buttercream with gumpaste brim (coated in buttercream) and gumpaste hand painted 1970 NFL logo. Dark navy frosting color was achieved using about half a bottle of blue gel over 6c frosting and about 1.5 grams of powdered black color. This is my first time using the powdered black frosting, and I'm pleased with it. The frosting has no bitter taste and darkened beautifully. I used the food dehydrator to quickly dry the gumpaste for the NFL logo. I had an NFL cap sitting by me as a model.
