Step 1

Mix together all the ingredients in a bowl. Add a sheet of parchment paper to a 9 x 9 pan. Place the ingredients in the pan and press it into an even layer. Use a small glass to roll over the top to get it smooth.

Step 2

Freeze the bars for 15 minutes. Remove the pan from the freezer and use the parchment to lift it out of the pan. Cut into 16 squares or 32 rectangles. Store refrigerated for up to 2 weeks. You can eat right away, or refrigerate for about 1 hour for a more solid texture.
