Chocolate Caramel Bars

UPDATE: New photos were added on 12/13/2011, and the recipe now includes a link to a printable version.

Did you have a favorite candy bar when you were a kid? I had a few that I preferred, but the best ever to my mind was a Twix. That’s why I was determined to get these cookie bars right even though it took a couple of tries. This all started when I read the recipe for millionaire’s shortbread in the Baked book, and it sounded straightforward enough. The concept is exactly what you see here which is a layered bar of shortbread, caramel, and chocolate otherwise known as a homemade Twix candy bar. I had a caramel disaster in that the sweetened condensed milk which cooked in a double-boiler (for more than twice the suggested time) never became caramelly or thick enough. Plan B was using store-bought dulce de leche, but that didn’t work either because even chilled it isn’t firm enough. But, then I remembered the chocolate caramel squares recipe I had mentioned from The Golden Book of Baking, and its caramel layer is built in a slightly different way. After comparing the two recipes, I ended up mixing and matching and adding my own touch by keeping the chocolate glaze from Baked and using the caramel from The Golden Book of Baking and sprinkling the chocolate with French sea salt. To clear up all this confusion, I’ll include the final, complete recipe below.

The shortbread cookie base was made first, and the two books differ in that the Baked version is richer with a little more butter and an added egg yolk. For my final version, I went with the more basic shortbread with no egg from Golden Book of Baking. While the shortbread cooled, the caramel was made. In the successful version, butter, sugar, light corn syrup, and sweetened condensed milk were combined in a saucepan over medium heat. It was stirred while the butter melted, then brought to a boil, reduced to a simmer, and stirred while simmering for about 20-25 minutes. The recipe suggests five minutes, but at that point it wasn’t caramel yet. I was not willing to accept failure number two, so I continued cooking until it looked right. From time to time during the 25 or so minutes, I would drop a little caramel onto a white plate to see the color clearly and how it set up at that point. When it looked like the filling in a Twix bar, the caramel was poured over the shortbread and was left to cool. Then, the chocolate glaze was made with melted chocolate, corn syrup, and butter. Once melted together and smooth, that combination was poured over the cooled caramel. Last, I sprinkled sea salt on the chocolate before it set because I’m addicted to doing that with anything involving chocolate and/or caramel.

So, finally, after testing, failing, tinkering, and persevering, I did produce what could be called a homemade Twix bar kind of cookie. The three steps can easily be spaced out over two days, and the steps are simple now that I know what works. I did store the cut bars in an airtight container in the refrigerator to keep them firm, but they are solid enough to remain at room temperature and would travel well. Now that I’m happy with this version of a Twix, I may have to move on to trying Michel Richard’s adaptation of a Kit Kat.

print recipe

Shortbread base:
2 c (300 g) all-purpose flour
2 teaspoons baking powder
1/4 teaspoon salt
1 cup (250 g) butter, softened
1/2 cup (100 g) sugar

Caramel layer:
1 c (250 g ) butter, cut into small pieces
1 c (200 g) sugar
4 tablespoons light corn syrup
2 cans (14 oz/400 g) sweetened condensed milk

Chocolate glaze:
8 oz chocolate of your choice (I used milk chocolate with about 40% cacao), chopped if from bars (I used feves)
1 teaspoon light corn syrup
1/2 c (125 g) butter, cut into small pieces
Fleur de sel for sprinkling

Shortbread base:
-Pre-heat oven to 325 degrees F (170 degrees C) and line a 9-inch by 13-inch baking pan with parchment paper.
-Combine flour, baking powder, and salt in a large bowl. Beat butter and sugar in a mixer on high speed until light and well-combined. Turn mixer speed to low and slowly add the dry ingredients. Place dough in the prepared pan and press into an even layer. Placing plastic wrap over the top and pressing with a flat-bottomed glass helps to spread and flatten the dough. Bake for 15-18 minutes or until golden. Cool pan completely on a rack.

Caramel layer:
-Place butter, sugar, corn syrup, and sweetened condensed milk in a medium saucepan over medium-low heat. Allow butter to melt, and stir to combine. Raise heat to medium-high and bring mixture to a boil, then reduce heat to medium-low again to maintain a simmer while stirring constantly. After ten minutes or so, you may want to switch to a whisk if the butter seems to be separating. For this step, the time could vary a lot depending on the heat of your burner, so watch carefully. The mixture should become a light amber, caramel color, and it should thicken a bit. You can drop a small amount onto a white plate to check the color and consistency while it's cooking. Mine cooked for about 25 minutes. When it reaches the desired color and thickness, pour mixture over shorbread, spread evenly with a heat-proof spatula, and allow to cool completely.

Chocolate glaze:
-In a large, heat-proof bowl, combine chocolate pieces, corn syurp, and butter pieces and place over a saucepan of simmering water. Cook, stirring constantly, until melted and well-combined. Remove from the saucepan and allow the chocolate glaze to cool for 30 seconds. Then, pour the glaze over the cooled caramel and spread evenly with an off-set spatula. Allow the glaze to sit and cool for a few seconds before sprinkling with coarse sea salt.

-Cut into narrow bars and serve with a little nostalgia on the side.
