It’s pretty much a given that I package up a batch of sweets with Nick when he returns to college. As a caramel fan like his mother, I knew these Ganache Topped Caramel Bars would put a smile on his face. They sure did!!

These Homemade Twix Bars have the 3 crucial components of the classic candy: Shortbread, Caramel, and Chocolate! You’ll fall for them with your first bite.

Why You Must Make

  • I’ve shared the similar Homemade Twix Bars recipe a couple of times which are also known as Millionaire Shortbread and probably have a couple of other aliases as well. All with 3 delectable layers including caramel. So you may not be shocked that I had to bake up these ganache-topped caramel bars!
  • If this trio of layers is calling your name, you won’t be disappointed.
  • This version has a homemade caramel version while others use melted grocery store caramels. 

As a preschooler, Nick used to accompany me on my errands, one being a weekly trek to the butcher shop for chops, hamburger, and such plus some thinly sliced ham for his sandwiches. He’d get a slice of ham to sample from the proprietor as our ham was being weighed plus there was the requisite trip to the candy jar on the counter for the coveted caramel.

So began his love affair with this confection. One in which his mother was happy to contribute–even now as he’s grown from that tot to a young man.

Recipe Tips

The shortbread crust was a piece of cake, but the first caramel attempt was a bit of a disaster. I have made desserts with homemade caramel from scratch as well as those using melted pre-made caramel candies. This caramel called for sweetened condensed milk and I thought it would be a no-brainer.

I cooked the mixture and watched it boil and eventually grow a little darker to an amber shade. But when I removed the molten sugar mixture from the stovetop, the butter had separated and the caramel was far from a smooth consistency. Flop. So I tried again, reducing the amount of butter and using a candy thermometer so I could pull the caramel off the heat at the perfect time. Success. Whew.

So you may also need a few tips to ensure your caramel layer is perfect!

  • All caramel recipes are different. Some are sweetened with white sugar, others with brown sugar. This is the first I’ve encountered with sweetened condensed milk, which is a substitute for the typical heavy cream and part of the sugar.
  • PRO Tip: To start this recipe, all ingredients are whisked together in a saucepan. This is also not typical of caramel recipes!
  • For the best caramel consistency, not too hard nor too soft, a candy thermometer (affiliate link) is imperative.
  • Whisk constantly so the mixture does not burn. Watch for the caramel to darken to a “caramel” color which should occur around 225 degrees, approximately 6 minutes into the cooking process. Pour over the crust when your caramel reaches temperature.
  • Make sure the caramel layer has cooled and solidified before adding the chocolate topping.
  • I used a small offset spatula to spread the chocolate layer over the caramel. 
  • Since these most likely will be stored in the refrigerator, you’ll want to cut them with a hot knife. I run a knife under very hot water and dry it off before slicing. The heat helps the knife glide through the chocolate and caramel.
  • PRO Tip: Remember this caramel mixture is extremely hot, so use caution when mixing, pouring, and spreading so you don’t get burned.

Homemade caramel tastes best and is a new skill to learn if you haven’t made caramels from scratch before. But an alternative is to melt store-bought caramels with a little cream for a semi-homemade version.
