Melt white chocolate and dark chocolate in separate bowls. I microwave each bowl for 1 minute at a time stirring until melted.

Add 1/2 cup of nuts to each bowl of chocolate and stir.

On a cookie sheet that is lined with wax paper, drop spoonfuls of chocolate mixture alternating white with dark.

With a knife gently swirl the chocolate together.

Add valentine's sprinkles as desired.

Refrigerate to firm for 30 minutes.

Break apart into pieces.
