In a large mixing bowl, combine the softened butter, cheese spread, mayonnaise, garlic salt, and salt on medium speed. Toss in the crab meat gently with a fork.
Spread the mixture on top of the muffins to make 12 crabbies.
Each crabbie should be cut into 4-6 pizza-like triangles.
Skip to the next step for do-ahead instructions. Place the crabbies on a baking sheet and bake for 10 minutes, or until bubbly and crisp, if serving immediately. Serve and have fun!
