Buttery shortbread cookies are transformed into petit chocolate caramel shortbread sandwiches filled with creamy chocolate caramel toffee sauce made in the slow cooker!
I am so excited to be participating in the Food Blogger Cookie Swap for the second year in a row!
This year over 500 food bloggers got together and made cookies. Sponsored by Dixie Crystals, OXO, and Land O Lakes, we shared our creation with three other bloggers and today we are all sharing our recipes online! Last year I made a Dark Chocolate Salted Caramel Almond Biscotti Bites. I ended up eating more than I exchanged, which is sad because I gained at least 7 pounds over the holiday season.
I will tell you that I signed up for the swap and had no idea what cookie I was going to make. I started thinking about ingredients and flavors that I like and that is what led me to this recipe.
Learning a new technique also sparked my creativity. Have you ever made caramel toffee sauce in the crock pot? I found a recipe for making toffee/caramel with a can of sweetened condensed milk. Boil an unopened can for 4 hours and it makes perfect caramel/toffee sauce? SHUT UP! There is no way that can work!! Total disbelief took over. Then an urgent need to try it right then and there!
First of all, who has 4 hours to stand in front of the stove and watch a closed can boil? Not me, until I was at church cooking on Wednesday and realized that I was going to be in the kitchen for the same amount of time. I grabbed a can from the church pantry (I gave the church money to replace it!) and threw it in a pot, covered it with water, and boiled away.
When the time I was up, I removed the can from the hot water, let it cool for about 15 minutes, and opened it up.
What I saw was nothing short of a miracle. Perfect caramel sauce! The albino sugar sauce that was in the can to start with came out a perfect amber color, poured like syrup when still warm, and tasted like decadent toffee. When it cooled down, it firmed up like a dense pudding. Able to hold its shape like frosting.
You might be wondering why I have two cans in this picture and why the one on the left is darker. Well, let me tell you that I found a chocolate flavored sweetened condensed milk. Like it could get any better?!?!? They also have a caramel flavored one, but I figured it would be dumb to make a caramel toffee sauce with caramel-flavored milk. Overkill much?
I thought the chocolate one would be a long shot anyway. Visions of bitter or burnt chocolate pudding flavor hovered in my brain, but NOPE! It tasted like perfectly caramel-y chocolate heaven!
1-Here are what the cans look like.
2-Here is the consistency of the milks prior to cooking.
3-Place your cans UNOPENED into the crock pot and completely cover with water. Use the slow cooker liners or take off the labels because the adhesive from the labels left a weird residue that was hard to clean off afterward. I wrote on the chocolate one with a sharpie in case the cans got mixed up.
4-Cook overnight on low for 8 hours.
5-You can cool and store the cans, unopened in the fridge until ready to use, or you can open them and eat right away. If it is still warm, you can pour it. I cooled mine down so I could use like frosting for my sandwich cookies. You can always just eat out of the can with a small shovel.
6-Once opened it will last in the fridge (in another storage container) for about a week. I just make a few cans at a time and then leave them unopened in the fridge. I wonder if you could leave them at room temp after you cook them without them spoiling? Anyone know? I would think you could because they have been processed, but don’t hold me to that! I wouldn’t be able to wait that long to use it:)
7-To warm up a can that has already been cooled down I just place the can in a pot of simmering water and then pour when ready. I have not tried microwaving it, FYI. If anything, I might put it in a double boiler on the stove and stir to melt.
Now you know how to make perfect toffee caramel and chocolate toffee caramel.
Let me show you what I did with mine!
I nestled mine in between two squares of buttery shortbread! Chocolate caramel shortbread sandwiches. I have made shortbread before. Click here to read my Dark Chocolate Pistachio Shortbread Cookie Recipe!
I just took my shortbread recipe, baked it into a thicker cookie bar, and added some of this glorious chocolate toffee caramel sauce!

I love this idea of using the crock pot to do the work for the caramel!! I will HAVE to do this the next time I’m making something with caramel (which, because of my husband’s caramel addiction, will likely be SOON!). Thanks for the great tip!

Once I found this tip, I have never looked back!!! Make a few cans at a time!

Amusingly I grew up with boiled can dulce de leche and we called it Brown Wiggle. Because, you know, we were such gourmandes lol. My mom now rolls her eyes at me when I call it dulce de leche! LOL, anyway, putting it in between 2 shortbread cookies is about one of the most delicious things I can imagine.
