We made our own ice cream sandwiches...yum...It's pretty easy to make your own!
First, we made sugar cookies. (You could also use chocolate chip cookies, oatmeal cookies, etc.) Once the cookies were baked, I let them cool on the cooling rack. I took the ice cream out and let it sit for a few minutes. You want it slightly softened so you can cut out slices for the sandwiches. Place a slice of ice cream between two cookies, and viola! Ice Cream Sandwich! (If the ice cream is too melty, stick the sandwich in the freezer for a few minutes.)
Don't feel like making cookies? Buy ice cream sandwiches at the store and pick up some sprinkles too!
To make these, simply unwrap the sandwiches (make sure they're cold and not melting or the sprinkles colors will run). Pour some sprinkles (I used Nonpareils) onto a plate. Press the sides of the ice cream sandwich into the sprinkles. If you have kids who don't like to get their fingers messy, cut 1" strips of wax paper. Wrap the strips around the middle of the ice cream sandwich and secure with a piece of tape. (These are easy to make and great for parties. You can use different colored sprinkles to fit your theme: orange and black for Halloween, red/green/white for Christmas, red/pink/white for Valentine's Day, pastels for Easter, red/blue/white for 4th of July. Match the colors of your birthday party and have an easy dessert! You can make them a day ahead and store in containers in the freezer.)
There are different kinds of ice creams sandwiches out there to enjoy: square, rectangular, mini, wheelies (round ice cream sandwiches), and in different flavors too!
