Potato Chip 7-Layer Bars are a fun twist on a classic favorite.  Before trying these I associated 7-Layer Bars with church potlucks and elementary school bake sales; a weird lumpy treat of incongruous ingredients.  That was until I got my hands on the Sugar Cube Cookbook.

Kir Jensen is one of my baking heroes.  (Yes I have baking heroes.  Don’t laugh.)  Her cookbook is a mandatory gift for any baker in your life.  Wanna try more or Kir’s amazing goodies?  The Sugar Cube’s pink food cart is now a brick and mortar location in NE Portland.

Potato Chip 7-Layer Bars

Makes 1 9×13 pan, 24 bars


  •  1 1/4 C pretzels
  • 1 C graham cracker crumbs
  • 1/2 C (1 stick) butter
  • 1 C salted, roasted cashews
  • 1 bag dark, semi sweet chocolate chips (around 2 cups)
  • 1 C butterscotch chips
  • 1 1/2 C sweetened, shredded coconut
  • 2 C thick, wavy potato chips
  • 1 can (14 oz) sweetened, condensed milk


Turn oven to 350.  Line 9×13 pan with parchment paper.  Spray sides of paper with non stick spray.

Use food processor or Ziploc bag with rolling pin to crush pretzels and graham crackers.  Melt butter in microwave.

Combine graham crackers and pretzel crumbs in bowl.  Add melted butter and salt.  Toss with a fork to combine.  Press into bottom of 9×13 pan.

Sprinkle on almost all of the chocolate chips.  Set aside 1/4 C.

Roughly chop cashews and add to bars.  Layer on shredded coconut and butterscotch chips.

Add remaining chocolate chips.  This makes some visible from the top layer.

Roughly crumble potato chips.  Sprinkle on top.  Quit sneaking them out of the pan.

Make holes in sweetened, condensed milk.  Drizzle entire can over the bars.  Yes it seems like too much but the whole can will be absorbed.  Don’t worry.

Bake for 15 minutes.  Rotate pan and bake for 15 more.  Watch pan closely during last 5 minutes, the top layer of potato chips will caramelize in the heat.

When bars are cool, slice and serve.  Watch people at work disrupt the meeting you took them to because they are confused by the potato chips.  Watch people at work disrupt the meeting again when they try them and fight over the last one.  These are an office favorite!
