Ever had Millionaire bars? Sometimes called Millionaire’s shortbread, they’re a layered bar of shortbread, caramel, and chocolate, similar to the Twix candy. But this cookie originates from the British Isles and it’s a delicious homemade treat. For our rendition of this famous bar, we’ve transformed it into an easy dessert and replaced the caramel layer with pecan butter! Our friends have been literally begging for the recipe. So without further ado…let’s make millionaire bars!

Tips for making these millionaire bars

The origin of the name millionaire bars is hard to prove: most sources claim it’s because of the rich ingredients inside! For this version, we’ve transformed these millionaire bars into an easy dessert recipe that’s a bit lighter than the original. And the best part is that instead of a caramel layer, it’s got pecan butter instead! The filling is so tasty, and it makes for a sort of cross between pecan bars and shortbread millionaire bars. Whatever the case, it’s an incredibly crowd pleasing dessert.

A few tips for these pecan butter millionaire bars.

  • You can use either butter and sugar, or maple syrup and coconut oil. Either works! The second option makes these into vegan millionaire bars.
  • Make homemade nut butter or sub store-bought! You can use any type of nut butter. We made homemade pecan butter, which requires a food processor. Or opt for store-bought peanut butter!
  • It takes a while to press the shortbread crust. Just keep pressing until it fills the entire bottom: we used a shot glass to roll the dough out into the pan.
  • You can cut these into any size you’d like! We found we liked the 1 inch by 2.25 inch rectangle. This makes 36 small millionaire bars: the perfect size for us!

Pecan Butter Millionaire Bars

  • Cook Time: 15 minutes
  • Total Time: 2 hours
  • Yield: 36 1x


These pecan butter millionaire bars have 3 layers: shortbread, nut butter, and chocolate! This easy dessert recipe couldn’t be tastier. Recipe revised December 2020.



For the shortbread layer

  • 1 ¼ cup all purpose flour*
  • ½ teaspoon kosher salt
  • 1 teaspoon baking powder
  • ¼ cup granulated sugar (or pure maple syrup)
  • ½ cup melted unsalted butter (or room temperature coconut oil)

For the nut butter layer

  • ¾ cup homemade pecan butter or creamy peanut butter
  • ¼ cup unsalted butter (or coconut oil)
  • ⅓ cup granulated sugar (or pure maple syrup)
  • 1 teaspoon vanilla extract
  • ⅛ teaspoon kosher salt

For the chocolate layer

  • 4 ounces or 2/3 cup dark chocolate chips (vegan if desired)
  • 2 tablespoons unsalted butter (or coconut oil)


  1. Preheat oven to 350 degrees Fahrenheit. Line an 9×9 inch square pan with parchment paper.
  2. Make the shortbread: In a medium bowl, stir together the flour and kosher salt. Add the melted butter (or room temperature coconut oil) and sugar or maple syrup and stir it together with a spoon. When it starts to come together, use your hands to knead it into a dough. Use your fingers to squeeze out any lumps in the coconut oil and knead until it comes together into a playdough-like texture. Press the dough into the pan in an even layer that covers the entire bottom; you can use a small glass to help roll it out (we used a shot glass!). Bake about 15 minutes until lightly browned on the edges. Allow to cool for about 15 minutes until room temperature.
  3. Meanwhile, make the pecan butter (optional): Go to Easy Pecan Butter for instructions. Measure out ¾ cup pecan butter for the recipe. 
  4. Make the nut butter layer: In a saucepan, melt the butter (or coconut oil), sugar (or maple syrup) and vanilla over low heat until the sugar is dissolved. Add the pecan or peanut butter and salt and stir until combined. Pour onto the cooled crust, shaking the pan as necessary to get an even layer. Freeze for 10 minutes. 
  5. Make the chocolate layer: Place the butter (or coconut oil) in a small saucepan over low heat and melt the butter. Remove from the heat and stir in the chocolate chips, stirring until fully incorporated and liquid. Immediately pour the chocolate layer onto the top of the nut butter layer. Refrigerate for at least 1 hour. 
  6. Cut the bars: Remove the bars from the refrigerator, loosen them from the edges of the pan with a sharp knife, and remove them from the pan using the parchment paper. Cut into 1 inch by 2.25 inch rectangles, to make 36 rectangles in all. (If there is any cracking, allow the chocolate to sit at room temperature for a few minutes to warm) Eat immediately or refrigerate until serving (the chocolate hardens more after a few hours, but it’s delicious immediately too).


*We don’t recommend using gluten free flour in this recipe; it’s a bit too dry!

  1. Love your recipes and love the taste of these bars! My pecan butter turned out really crumbly though. Do you know why? Is there such a thing as over processing? It also separates from the shortbread.

    1. Thank you so much for letting us know. The pecan butter should come to a creamy consistency — you can drizzle in more oil and continue processing if it is too crumbly. I added a note about this to the recipe to help with troubleshooting. We are so sorry that it turned out too crumbly!

    1. We don’t recommend freezing since the bars can separate, but if you’re ok with the risk you can go for it!
