Loaded with toasted pecans, these Pecan Toffee Bars have a shortbread crumb base and a caramel, pecan center. Topped with melted milk chocolate, these bars are just heavenly! This is a holiday confection that will be difficult to share and part with. Maybe it’s a good idea to make a double batch of these after all!

It should come as no surprise to you, Dear Reader, that I bake a lot! Nearly one hundred percent of the time, I package up the baked goods once they are photographed and John.e will walk them over to one of our neighbours. Very rarely does it happen that I keep all of a particular baked good for ourselves. Yet, that is exactly what happened with these Pecan Toffee Bars. Sometimes something is just so good, it’s hard to share!
Speaking of toffee, do you love it or hate it? There seems to be two schools of people when it comes to toffee-flavoured items. There are people that absolutely love it and can’t get enough of it. And, then there are those who don’t like it at all. Are there any in-between people? I really don’t get what’s not to love. It’s sticky and sweet and tastes buttery and creamy. Um, excuse me while I run to the fridge to fetch another Pecan Toffee Bar! Be right back!

My third series this year is the second volume of my 12 Bars and Squares of Christmas! You can find the first bars and squares series here! Before we get to a list of ingredients and instructions for today’s recipe, let me tell you about this series and more!

INGREDIENTS NEEDED TO PREPARE THIS RECIPE
The following is a list of the ingredients needed to prepare this recipe. For exact amounts and measurements, refer to the printable recipe card located near the bottom of this post.
- Flour – I’m using all-purpose flour. This recipe has not been tested with other flour options.
- Brown Sugar
- Butter – Salted butter works best here.
- Pecans – Toast your pecans first for optimum flavour.
- Milk Chocolate Chips
- Vegetable Oil
HOW TO MAKE PECAN TOFFEE BARS
To prepare the base, preheat your oven to 350 degrees F. Line a 9×13-inch baking pan with parchment paper. Set aside. Measure the flour, brown sugar, and butter into a mixing bowl. Beat until well combined. The mixture should look dry – almost like lightly wet sand. Transfer the mixture to the prepared baking pan and lightly press into the pan to form a flattened crust. Sprinkle over the toasted whole pecans. Set aside.
For the middle, in a saucepan, measure in the butter and brown sugar. Over medium heat, cook the butter and brown sugar, stirring constantly, until the mixture begins to bubble. From that point, cook for one minute while stirring. Pour this mixture into the baking pan over the pecans. Bake for 18 minutes or until the top is bubbling. Remove the pan from the oven and set aside.
Finally, for the top, place the chocolate and vegetable oil into a microwave-safe bowl. Microwave it at half speed for 30 seconds. Stir well and microwave in 30-second increments, stirring between each increment, until melted and smooth. Pour the chocolate over the pecan and caramel layer. Use a spatula to smooth it out. Set aside to cool for 2-4 hours. Cut into squares. Transfer the squares to a food-safe container and keep them refrigerated.

TOASTING PECANS
The first thing you should do it to toast your nuts. How do you do that? It’s very simple! To be perfectly honest, this applies to any nuts or seeds, not just the nuts in this recipe. If you are not familiar with toasted nuts, then please try it just once. You will probably never revert to using nuts in your cooking or baking again without toasting them first!
I have tried using non-stick frying pans for toasting, but nothing works as well as a stainless steel pan. You could use a cast iron pan, but since they get very hot and retain heat so well, it’s easier to burn the nuts. See the frying pan in this picture? That’s the exact one that I use all the time. I’m not suggesting you run out and buy this same cookware set, but I want you to see the pan – remember, do not use non-stick if possible. You’ll get better results will plain stainless steel.

So, unlike most cooking where you’re required to preheat first, you don’t want to apply that same rule to toasting nuts. Add the nuts to a cold pan. Place the pan on the burner and turn the heat on – no higher than medium and probably even less if using a gas burner.
Keep the nuts moving about. I use a rubber spatula. Once you start to smell that warm and toasty aromatic smell, pay close attention. The nuts will take on a darker colour. Don’t let them get too dark. Once you’re satisfied, immediately remove them from the hot pan and transfer them to a dinner plate where they can be spread out to cool.

STORING, PACKAGING, & FREEZING
Most no-bake confections are made without the need to freeze them for long periods of time, but they can be frozen. For this recipe, I have tested whether or not they can be frozen, and they certainly can! Once they are completely firm, pile them into a clean, food-safe container. The container must be freezer-friendly! You’ll want to ensure a very tight-fitting lid too. I use these quite often when freezing baked goods. I like to place a sheet of plastic wrap over the top of the container before pushing the lid on. This helps to create a better seal. The goal is to keep all of that freshness locked in! You can freeze these for up to three months.
If you plan to give previously frozen bars or squares as a gift, I would lay them out on a wire cooling rack to thaw completely. Once thawed, pile into cellophane bags and tie with a ribbon, or stack in a cookie tin/box.
