Peanut Butter Twix Bars

by Allison @ Alli 'n Son on January 5, 2012

It’s National Shortbread Day! I bet you didn’t even know.

To celebrate, I’m making up some homemade Twix bars.

Why homemade Twix bars you ask? Because hidden under a layer of rich, dark chocolate there’s a layer of oh-so-creamy peanut butter. Under that creamy layer is a melt-in-your-mouth, brown-sugar layer of shortbread.

Oh yes. I did it. I created homemade peanut butter Twix bars.

They are rich. They are decadent. They are fulfilling, heavy and satisfying.

They are, dare I say, better than the actual candy bar.

Yes, I said it. They. Are. Better.

And so, happy Shortbread Day. It’s just the excuse you need to make, eat and possibly even share a few of these.

As if you really needed an excuse anyway.

Peanut Butter Twix Bars

Peanut Butter Twix Bars


    Brown Sugar Shortbread Layer
  • 2 sticks unsalted butter, softened
  • 1 cup packed brown sugar
  • 2 cups all purpose flour
  • 1/4 teaspoon fine sea salt
  • Peanut Butter Layer
  • 1/2 package graham crackers, crushed 3/4 cup
  • 2-1/4 cups powdered sugar
  • 1-1/2 cups creamy peanut butter
  • 1 stick plus 1 tablespoon unsalted butter, softened
  • Dark Chocolate Layer
  • 2 cups dark chocolate chips
  • 1 teaspoon honey
  • 1/2 cup unsalted butter


    Brown Sugar Shortbread Layer
  1. Preheat oven to 325°F.
  2. Coat a 9 x 13 pan with nonstick spray.
  3. Using electric mixer on medium speed cream the butter until light and fluffy.
  4. Add the brown sugar, beating well.
  5. On low speed mix in the flour and salt until just combined. Do not overmix.
  6. Press the dough into the prepared pan.
  7. Bake in preheated oven for 20-22 minutes, or until the shortbread is brown, firm at edges and slightly soft in center.
  8. Let cool completely.
  9. Peanut Butter Layer
  10. Using an electric mixer, mix together the peanut butter and butter until smooth and creamy.
  11. Add in the graham cracker crumbs and powdered sugar until well combined. The mixture will be crumbly.
  12. Using a spatula, gently press the peanut butter mixture on top of the cooled shortbread layer. This takes a bite of work, the mixture is sticky.
  13. Chill in the refrigerator for 1 hour to firm, then smooth with a spatula.
  14. Dark Chocolate Layer
  15. In a small microwave-safe bowl combine the chocolate chips, honey and butter.
  16. Microwave on high for 1 minute. Stir.
  17. Continue microwaving on high, stirring every 20 seconds until fully melted.
  18. Pour over the peanut butter layer, smoothing with a spatula.
  19. Chill in the refrigerator until chocolate hardens.
  20. Cut into rectangles.
  21. Store in the refrigerator.
