Salted Caramel Chocolate Shortbread Bars
It’s officially Christmas cookie season. That means, for the next couple of weeks (probably through New Year’s) it will be all Christmas cookies all the time. This year, I’m going the slightly nontraditional route with my tins, including some new recipes and experiments, but if you’re looking for some classics, here’s last year’s selection:
Anyways, this week’s recipe was definitely an experiment. I had seen it on Pinterest and thought they looked amazing. Also, I needed to make something that would keep for a week since I’ll be making the rest of my cookies in a bit of a cookie making binge next weekend.
Side note: when I told my mom my plans of baking for the entirety of next weekend, she immediately recommended I invite friends over to help. I had to explain to her that I actually love listening to Christmas music and spending the day alone in my kitchen making cookies. If that makes me an introvert I’m totally OK with that.
So, it starts off pretty straight forward. Whisk together the flour, baking powder, and salt in a small bowl and set aside.
Then, combine the butter and sugar in the bowl of a stand mixer and beat on medium speed for about 2 minutes, or until fluffy.
Add the flour mixture to the butter mixture and beat on low speed until just combined. It will be in smallish pieces.
Press the dough into the bottom of a 9×13 inch pan lined with parchment paper. You don’t want to skip the parchment paper on this one – it’s going to come in very handy when you go to cut the bars later.
Bake at 325°F for about 15 minutes or until edges are golden. Put on wire rack to cool completely.
At this point, I was cruising along, feeling totally fine about my decision with this recipe. My shortbread layer looked great, life was good.
Then, I came to the caramel layer. Now, I think I’ve discussed my fear of caramel before, but I couldn’t find the post to reference, so I’ll say it again: I am always afraid that I will burn the sugar. And burnt sugar is possibly the worst smell ever. It’s amazing that something so sweet and innocent can turn so vile and disgusting in about 5 seconds flat.
To add to this fear, this particular recipe called for a different combination of things to make the caramel than I was used to. I’ve made caramel using actual caramels and melting them with sweetened condensed milk. I’ve made it with just sugar and butter. But this called for a weird combination of the two: butter, sugar, karo syrup, and sweetened condensed milk.
However, the shortbread had gone beautifully, so I had no reason to doubt the recipe yet. I went ahead and trusted it. I combined the four ingredients in a medium saucepan, heating it over medium heat until the butter melted, stirring frequently.
Then, I increased the heat to medium high, hoping to bring it to a boil while stirring constantly, after which I would reduce the heat to a simmer and continue to stir constantly until it turned amber in color. Alas, it was not to be. I began to notice little flecks of amber in my supposed caramel. I was pretty sure that wasn’t how it was supposed to work, but I pushed on.
Turns out, my sugar found its way into the corners (round pans don’t have corners, but you know what I mean) of my saucepan and begin to do that terrible thing where it burns. Even my constant stirring didn’t prevent it. When I realized what was happening, I turned the heat down to simmer and just stirred until it turned less bright whitish-yellow than sweetened condensed milk, and called it a caramel, which I then poured over the shortbread layer.
Now, it may be that I was just overconfident and got lazy, and your caramel layer may turn a beautiful amber. But I think if I were to make these again, I would use the caramel from my Peanut Butter Samoa Bars recipe instead of the one they had here. Fortunately, the end result, though maybe not as caramel-y as it was supposed to be, is still 100% delicious.
After letting the caramel cool for a bit, I put it in the freezer to chill overnight. You definitely don’t have to let it chill that long, I just didn’t feel like finishing it last night.
For the chocolate layer, I did decide to stray from the recipe’s suggestion of a double boiler and used the microwave method instead.
Combine the butter, chocolate, and karo syrup in a microwaveable bowl. Heat in 15 second intervals at 50% power, stirring after each interval, until smooth.
Pour the chocolate layer over the caramel layer and sprinkle with sea salt. Chill until ready to cut and serve.
These will keep in the freezer (and taste better out of the freezer), for as long as you want. I cut them into bars and wrapped them individually in plastic wrap, but that’s more because they’ll be going in tins later. End product: a slightly less caramel-flavored Twix bar.
Enjoy!
