I recently bought extra large cake pan and wanted the first thing I baked in it to be a  cookie cake.  

I though I would make one using a yellow cake mix,  sugar cookie mix, some eggs, melted butter, vanilla and top it with a simple vanilla buttercream frosting and sprinkle it with yellow and blue colored sugar (Go Sabres).

• Ingredients list
• 1 yellow cake mix
• 1 sugar cookie mix
• 3 eggs
• 1 cup butter, melted
• 1 tbs vanilla

Directions – preheat oven to 350 degrees.  Line a large round cookie pan with tin foil and spray with baking spray.  Set aside. 

In a bowl, combine cake and cookie mixes.   Blend in eggs, one at a time, then butter and vanilla.  Press evenly into prepared pan.  Bake 18 minites, no longer. Cool completely.

• Frosting ingredients
• 1/2 cup butter, softened
• 4 cups powdered sugar
• 2 tbs milk
• 1 tsp vanilla

Directions – in a bowl,  mix butter and powdered sugar.   Blend in milk and vanilla.  You can add more milk and/or powdered sugar to get the desired consistency.  Frost cooled cookies. 

  I sprinkled colored sugar on top.

Cut and storte in covered container.
