In The Test Kitchen
I tested this a few times to get the caramel just right because that’s where these bars either shine or fall flat. The key was keeping the heat low and letting it slowly thicken instead of rushing it. Once it hits that glossy, golden stage and coats the back of a spoon, you get that soft, sliceable caramel layer that holds perfectly without oozing everywhere. Pair that with the buttery pretzel shortbread and it’s one of those recipes people immediately ask for.
Ingredient Notes
For the Shortbread Base
Best Choice
Unsalted butter for control over salt
Substitutions
Salted butter works, just reduce added salt slightly
For the Caramel Layer
Best Choice
Sweetened condensed milk (full-fat only)
Substitutions
Golden syrup can be swapped with light corn syrup
For the Topping
Best Choice
Semi-sweet chocolate for contrast
Substitutions
Milk or dark chocolate both work
Where to Find
Coconut oil is usually near baking oils

Step By Step Instructions
1
Prep The Pan
First things first, preheat your oven to 350°F (177°C). While it’s heating up, grab a 9×13-inch baking pan and line it with parchment paper. Make sure to leave some overhang on the sides—this will be your secret weapon for lifting the bars out easily later
2
Make the Shortbread Base
Beat the butter until smooth, then mix in 2 cups flour, ½ cup crushed pretzels, ½ cup sugar, ½ teaspoon salt, 2 egg yolks, and 2 teaspoons vanilla until crumbly. Press firmly into your lined pan in an even layer.
3
Bake Until Lightly Golden
Bake at 350°F for about 25 minutes until the edges turn lightly golden and the center looks set. Let it cool completely before adding anything on top.
4
Cook the Caramel Low and Slow
In a saucepan, combine the condensed milk, 14 tablespoons butter, both sugars, syrup, and salt. Stir constantly over medium-low heat until thick, golden, and bubbling, about 15 minutes. It should coat the back of a spoon. Stir in the vanilla.
5
Pour and Set the Caramel
Pour the caramel over the cooled crust and spread evenly. Let it set until firm, about 1 hour at room temperature or 30 to 45 minutes in the fridge.
6
Add Chocolate and Finish
Melt the chocolate with the coconut oil until smooth. Spread over the caramel, then scatter 1½ cups pretzel pieces on top and press lightly. Chill for 30 minutes until set, then lift out and slice.

Recipe
Salted Caramel Chocolate Pretzel Bars
Ingredients
Shortbread Base
- 1¼ cups unsalted butter (slightly softened, 2 ½ sticks )
- 2 cups all-purpose flour
- ½ cup finely crushed pretzels
- ½ cup granulated sugar
- ½ teaspoon salt
- 2 large egg yolks (at room temperature)
- 2 teaspoons vanilla extract
Homemade Caramel Layer
- 28 oz sweetened condensed milk (two 14 oz/400g cans)
- 14 tablespoons unsalted butter (cubed)
- ½ cup light brown sugar (packed)
- ½ cup dark brown sugar (packed)
- ⅓ cup golden syrup (or light corn syrup)
- ¾ teaspoon table salt
- 1 teaspoon vanilla extract
Toppings
- 12 ounces semi-sweet chocolate chips ( or chopped chocolate, about 2 cups)
- 1 tablespoon coconut oil (plus 1 teaspoon)
- 1 ½ cups broken pretzel pieces
Instructions
- Preheat your oven to 350°F (177°C). Line a 9×13-inch baking pan with parchment paper, leaving extra on the sides to lift the bars out later.
- In a large bowl, beat the butter on high speed until smooth and creamy — about 1 minute. Add the flour, crushed pretzels, sugar, salt, egg yolks, and vanilla extract. Mix until crumbly but combined.
- Press the dough evenly and firmly into the prepared pan.
- Bake for about 25 minutes, or until the edges are lightly golden. Set aside to cool completely before adding the caramel.
- Combine the sweetened condensed milk, butter, brown sugars,golden syrup, and salt in a medium-sized heavy-bottomed saucepan over medium-low heat. Stir frequently until the butter is melted and everything is well combined.
- Continue to stir constantly as the mixture thickens, turns golden caramel in color, and begins to bubble — this will take about 15 minutes or more, depending on your stove. Do not increase the heat or the mixture may scorch or separate.
- Use an instant-read thermometer if you have one — the caramel should reach about 225°F (107°C) and coat the back of a spoon.
- Remove from the heat and stir in the vanilla extract. Pour the caramel evenly over the cooled shortbread crust. Let it cool at room temperature for several hours or refrigerate for about 1 hour before adding the chocolate layer.
- Pour the hot caramel evenly over the cooled shortbread crust. Spread it out with a spatula, then let it cool completely until firm — about 1 hour at room temperature or 30 minutes in the fridge.
- Melt the chocolate and coconut oil together in 15-second intervals in the microwave, stirring until smooth. Pour the melted chocolate over the caramel and spread evenly.
- While it’s still soft, scatter broken pretzel pieces over the top and gently press them in so they stick.
- Set the chocolate by placing it in the refrigerator for 30 minutes. Once fully set, lift the bars out using the parchment overhang and cut into squares or rectangles.

- Stir constantly once it starts thickening to prevent scorching
- Use parchment overhang so you can lift the bars cleanly
- Let the chocolate fully set before slicing for neat edges
- If your pretzels are very salty, taste before adding extra salt anywhere

FAQs
Why is my caramel too soft?
It likely didn’t cook long enough. It should thicken and coat a spoon before removing from heat.
Can I use store-bought caramel?
You can, but it won’t set as firmly or have the same rich flavor.
Do these need to be refrigerated?
Not required, but chilling helps them stay firm and slice neatly.
How do I cut clean slices?
Use a sharp knife and wipe it clean between cuts for the best edges.
