Now let's talk scrumptious Marbled Peanut Butter & Chocolate Shortbread Bars! ... photographed on my gorgeous cherryBLOX cutting board, of course.

These little bars of deliciousness were a happy accident.  An act of pure desperation, actually.  Yup, I totally messed up a recipe ... annnddddd these were born.  With a layer of scrumptious shortbread covered in a thick layer of white chocolate and peanut butter, all topped off with a marbled swirl of semi-sweet chocolate, how could the accident be anything but happy?

You know those days when you're very short on time ... I mean, like crunching right down to the very last second you have ... and you've committed to make something for an event?  Well, the day these bars were born was one of those days.

I had committed to bringing the sweets for a group get-together, which is something I love to do.  'Cause, as you know if you come by here often, I'll take any excuse I can to bake.  So I decided to make a peanut butter and chocolate bark I'd had my eye on for a while.

Well, let's just leave it at ... the bark didn't work.  At all.  It tasted totally yummy, but it was ooey-gooey and didn't set up at all.  A total mess.  And I didn't have time to make something else.  Ugh.

I fretted and fretted.  What was I going to do?  I couldn't show up at the get-together empty-handed!

And then an idea struck.  What if I turned the {failed} bark into the topping of a bar?  I could pull that off pretty quickly, I thought!  {I had all of about 40 minutes before I needed to be at the get-together.}

I quickly mixed up and baked up a simple shortbread crust.  Then, I cut large pieces of the ooey-gooey peanut butter {failed} bark in sheets and layed it on top of the warm crust ... stuck it back in the oven for just a minute or two to melt and adhere the bark onto the crust ... and then flash-chilled it all in the freezer.

Whew!  It worked!  And it was deeee-licious.

Probably needless to say, I was a wee bit late for the get-together.  But happily, these Marbled Peanut Butter & Chocolate Shortbread Bars were a total hit.

Aaahhhhhh, you gotta love happy accidents.

Now, here's how to make these beautiful bars the non-accident way.

Line a baking dish with aluminum foil to create a sling ... you're doing this because it makes it soooooo much easier to cut the squares.  Simply lift the entire slab out of the pan by the foil overhang, set it on a cutting board (ahem ... like a gorgeous cherryBLOX personalized cutting board), pull back the foil from the edges, and cut.  Easy-peasy.

Then, press a simple shortbread dough mixture evenly into the bottom of the pan and bake it up.

While the crust is baking, melt together some white chocolate and crunchy peanut butter.  Resist the temptation to eat it all by the spoonful.  It'll be hard ... but you can do it.

Spread the peanut butter mixture evenly over the shortbread crust as soon as it comes out of the oven ...

... and then drop on some stripes of melted semi-sweet chocolate, like this:

To create the really pretty marbled effect, simply run a sharp knife back and forth through the peanut butter mixture, perpendicular to the chocolate stripes, like this:

Aren't they pretty?

So, what are you waiting for?  Go whip up a batch of these totally heavenly happy-accident Marbled Peanut Butter & Chocolate Shortbread Bars ... your tummy will be so glad you did!  And be sure to create your very own personalized cherryBLOX cutting board to cut them on.  I'm pretty sure these gorgeous cutting boards may just make these scrumptious bars taste even better.

Marbled Peanut Butter & Chocolate Shortbread Bars

A simple shortbread crust layered with white chocolate and peanut butter, topped off with a marbled swirl of semi-sweet chocolate. They're little bars of pure deliciousness!
Prep time: 25 MCook time: 30 MTotal time: 55 M


  • 2 c. all-purpose flour
  • 1/2 c. granulated sugar
  • 1/2 tsp. salt
  • 1 c. butter, just slightly softened
  • 1 (12 oz.) package white chocolate chips
  • 1 1/4 c. crunchy peanut butter
  • 1/2 c. semi-sweet chocolate chips


For the Crust:
  1. In a mixing bowl, combine flour, sugar, and salt. Cut butter into small pieces and add to flour mixture. Beat with an electric mixer on slow speed until the mixture resembles coarse crumbs with a sandy consistency. 
  2. Press flour mixture evenly into the bottom of a 9x13" baking dish lined with aluminum foil (let the foil overhang the edges of the pan, creating a foil 'sling'). 
  3. Bake at 350 degrees for 25 minutes.
For the Peanut Butter Topping:
  1. In a saucepan over medium-low heat, melt together the white chocolate and peanut butter. 
  2. Spread evenly over the still-warm crust.
For the Marbled Chocolate:
  1. Melt the semi-sweet chocolate chips (about 45 seconds in the microwave or in a small saucepan over medium-low heat); stir until smooth.
  2. Drizzle stripes over the warm peanut butter topping. To marbelize, use a sharp knife to draw lines through the peanut butter mixture perpendicular to the chocolate stripes.
  3. Refrigerate for about 30 minutes or until set. 
  4. Use the edges of the foil "sling" to lift bars from the pan. Cut into small squares.
