Preheat the oven to 325℉ and line a baking sheet or jelly roll pan with parchment paper.
Make the Caramel
Heat the 1/2 cup butter and 1 cup dark brown sugar firmly packed in a sauce pan over medium heat until the sugar dissolves, add the 1/2 teaspoon vanilla extract and bring to a boil, and cook until it thickens.
Make the cracker candy
Spread 40 saltine crackers on the prepared baking sheet. Pour the caramel over saltine crackers.
Bake in the oven for 5 minutes.
Sprinkle 12 ounces mini chocolate chips over the surface of the caramel.
Return to the oven for 1 minute, then spread the melted chocolate chips evenly over the caramel.
Decorate
Melt 6 ounces candy melts and pipe over the chocolate.
Decorate with 1/2 cup sprinkles of your choice.
Cool
Cool completely, then refrigerate until very firm.
Break into pieces, and share (or devour).
Notes
Be careful with the hot caramel, that stuff will cause serious burning if you spill it!
Use different colored sprinkles and decorations, depending on the occasion.
Vary up the chocolate – white chocolate is also super yummy with this!
