Line a baker's half sheet pan (approximately 13"x18") or a jelly roll pan (approximately 10"x15") with parchment paper.
Melt almond bark slowly over medium-low heat, stirring often so it doesn't burn. Once it's melted and smooth, turn the heat down to low and stir in the peanut butter. Mix until creamy. Remove from heat.
In a small saucepan, melt the chocolate and butterscotch chips together over medium-low heat. Stir frequently.
While the chocolate is melting, throw the crushed Boston baked beans candy into the melted almond bark peanut butter mixture and stir until combined. (Remember to keep stirring the chocolate chips.)
When the chocolate chips are melted, remove from heat.
Spread the almond bark mixture evenly into the prepared pan. It works best to use an offset spatula if you have one.
Scatter the chocolate and butterscotch mixture over the base layer. Using the offset spatula or a butter knife and without disturbing the almond bark mixture too much, gently swirl the chocolate into the almond bark using figure-8 motions. You've now created tiger stripes.
Toss the crushed dry roasted peanuts on top, lightly pressing down so they harden into the chocolate.
Cool until hardened. Lift the candy from the pan and break into pieces. Store in an airtight container in a cool place or in the refrigerator.
