how to make a ice cream sandwich

Step 1: Ingredients

Here's a basic recipe for your chocolate ice cream sandwich cake.  Fill it with whatever your heart desires.  I'll keep working on the vanilla cake (same recipe, minus the cocoa), and let you know how it goes!

• 1/2 cup (113 grams) unsalted butter, melted
• 1/2 cup (100 grams) white granulated sugar
• 1 large egg
• 1 teaspoon pure vanilla extract
• 1/2 cup (65 grams) all purpose flour
• 1/4 cup (25 grams) unsweetened cocoa powder
• 1/4 teaspoon salt
• 4 cups (2 pints) (950 ml) Ice Cream (Homemad or Store Bought), slightly softened - see what happens in step 6 if you let it get too melty!!
• 10 x 15 inch (25 x 38 cm) rimmed baking sheet
• Parchment paper

Step 2: Prepare your pan

Preheat oven to 350 degrees F (180 degrees C) and place rack in center of oven. The first time I made this, I used parchment paper in a 10 x 15 inch (25 x 38 cm) baking pan. The second time, I slipped a silicone sheet (Sil-Pat) over a cookie tray and just spread the mixture on it carefully. Both methods worked, but I prefer the less hassle of the cookie sheet.

Step 3: Melt Butter

Chop up your butter and microwave it for 30 seconds to a minute. Alternatively, melt it over low heat on the stove. Stir stir stir, to make sure all of the butter is melted, but not boiling.
