Millionaire’s Shortbread, aka Homemade Twix Bars

5 Sep

Happy labor day, all! Today my husband and I headed to his grandmother’s house for a little family get-together. I love these family gatherings because I not only get to see the family (including two cute babies), but I also have an excuse to bake and pawn off my desserts onto others. The family has come to expect a new dessert each time I come, and I’m happy to oblige 🙂

So last night I decided to try out a recipe for millionaire’s shortbread. At first I was a little hesitant because many of the reviews on the Food Network website indicated it was a giant hassle to make, but on the other hand, other reviews indicated that it was easy and delicious [and that those leaving reviews to the contrary had obviously not followed the directions]. Well, I’m good at following directions, and I had been tempted to make this dessert after being inspired by several food blogs lately, so I forged ahead.

I’m so glad I did!! Sure, it’s a little time consuming, but not difficult. And, it was definitely worth the wait! Luscious dulce de leche, sandwiched between soft shortbread and rich milk chocolate…does this sound familiar?

Yes, it has all the flavors of a twix bar, but of course much better. Maybe twix bars fit for a millionaire? 🙂

Millionaire’s Shortbread

(adapted from recipe by Claire Robinson)


For the Shortbread-

  • 2 sticks butter, cut into small pieces, plus more for preparing pans
  • 2 cups flour, plus more for preparing pans
  • 2/3 cup sugar
  • 1/2 teaspoon salt

For the Dulce de Leche Layer-

  • 2 (14-ounce) cans sweetened condensed milk
  • 2 tablespoons butter
  • Sprinkle of salt

For the Chocolate Layer-

  • 11.5 oz bag milk chocolate chips


  • Preheat the oven to 350 degrees F.
  • Butter a 9×13 inch pan and coat with flour, tapping off excess.
  • To make the shortbread: Place the flour, sugar, and salt in a food processor and pulse once. Add butter and pulse until mixture resembles peas. Press the shortbread mixture into prepared pan and bake until golden brown around the edges, about 20-25 minutes. Remove from the oven and let cool completely.
  • To make the dulce de leche layer: In a heavy-bottomed saucepan over medium heat, combine the condensed milk and 2 tablespoons of butter. Bring the mixture to a boil, stirring continuously to ensure it doesn’t burn. Once the mixture begins to boil, reduce heat to medium-low and continue stirring until the mixture becomes thick and amber in color, about 15-25 minutes. When finished, immediately pour the dulce de leche over the cooked shortbread and spread evenly. Sprinkle dulce de leche layer with a small amount of salt, and cool to room temperature.
  • To make the chocolate layer: In a glass bowl, heat chocolate chips in the microwave as directed on the package, stirring after one minute. Once the chocolate has melted, pour it over the cooled dulce de leche layer. Cool at room temperature for about 10 minutes, then place in the refrigerator to cool completely, allowing the chocolate to harden slightly but not get hard.
  • Cut into small squares and enjoy at room temperature, or keep in the refrigerator for a cool treat.

    Do you know how long it keeps? x

      Haha, they only lasted two days in my house, but that’s because we gobbled them up so quick 🙂 I would guess they could keep for a lot longer though, especially in the fridge. Maybe a week or two?
