Cover your workspace with waxed paper or parchment paper.
Spread a layer of peanut butter on one cracker, top with another cracker until all the crackers are used up.
Melt the chocolate almond bark in a microwave safe bowl for 1 minutes, then stir. If there are small lumps when you first take it out, just keep stirring to see if they melt.
Heat in 30 second increments until the chocolate is melted.
Dip the crackers in the chocolate and let the excess drip off.
Lay on the waxed paper to cool.
Immediately add the sprinkles if you desire.
Once cooled, you may melt the vanilla almondbark as above and decorate the tops of the cookies as desired.
