    I have always been a huge fan of anything that contains caramel as I have a super sweet tooth! So if you have a sweet tooth too then this is the recipe for you.

    These caramel bars are known by many names such as millionaire's shortbread, caramel shortcake, chocolate caramel bars, and caramel shortbread. You can call this easy gluten free caramel slice whatever name you prefer and I am sure you won't be disappointed.

    Is Caramel gluten free?

    Caramel is usually gluten free as it is made mainly with milk, sugar, and butter and does not contain ingredients containing gluten. If buying ready-made caramel sauce I recommend always checking the ingredients label as some brands may contain gluten due to flavorings used within the caramel sauce.

    For this recipe, I recommend making homemade caramel as tinned caramel will not be thick enough to set and will create a saucy mess when you slice into the caramel slices as well as being sure your caramel is gluten free.

    Ingredients

    Equipment

    • 8×8 lined baking tin
    • non-stick pan

    Gluten free Shortbread recipe

    • Butter - Be sure to have your butter at room temperature as this will make it easier when beating together with the sugar.
    • Caster sugar - Don’t worry if you can’t get caster sugar for this recipe. Superfine granulated sugar or regular granulated sugar will also work well.
    • Gluten free plain flour - I used Doves Freee Plain flour but you can use your preferred brand of gluten free plain flour or Gluten free all-purpose flour.
    • Cornflour - If in the US be sure to use Corn starch. As I am in the UK it is called cornflour but not to be mistaken with the US cornflour (yellow powder).
    • Xanthan gum - Used as a binding agent in gluten free baking. Essentially acting like gluten keeping everything together.

    Caramel layer

    • Sweetened condensed milk - I used Carnation condensed milk in this recipe but you can use your preferred brand of sweetened condensed milk.
    • Brown sugar
    • Butter

    Chocolate Topping

    • Chocolate - I used milk chocolate in this recipe but it would also work with dark chocolate for this gluten free chocolate caramel slice. If you want to make gluten-free white chocolate caramel slice then just switch out the milk chocolate for white chocolate. 
    • White chocolate - Optional if you want to add some extra flair to your gluten free millionaire bars and create a beautiful feathered finished look.

    Instructions

    Recipe steps

    • Optional-Melt white chocolate and place it in a piping bag with a small narrow piping nozzle or a small hole on the bottom of the piping bag.
    • Carefully pipe the white chocolate in parallel straight lines over the top of your melted milk chocolate. Using a wooden skewer or the back of a knife gently drag through the lines at a 90° angle to make a beautiful feathered design.
    • Leave to fully set. You can place it in the refrigerator for a faster setting.

    Recipe Tips

    • Gluten Free Flour – I used a shop bought Gluten free flour blend from Doves Farm Freee from range. Which is a flour blend of Rice, Potato, Tapioca, Maize and Buckwheat flour. I have had reports that others have used Bob’s Red Mill and other Gluten free All purpose blends with my recipes that have worked well. I would love to know what flour blends worked for you. So feel free to get in touch by leaving a comment below or you can contact me directly.
    • Kitchen Scales - Using digital scales is recommended when baking. I always measure using scales and in grams as baking is a science. When baking gluten free it is essential to weigh out ingredients to get the best results! There is no need to purchase expensive digital scales and you can find them available cheaply online.
    • Oven Temperatures - Your oven temperature may be slightly different. As all ovens vary in temperature and the baking time is used as a guide. Some ovens run hotter than others. You could invest in an oven thermometer to be more accurate.

    Variations

    There are a few recipe variations that can be done for this millionaire's shortbread recipe and I thought I would also include them below as you might find them helpful and you can adapt easily to suit your preferred outcome.

    • Gluten free white chocolate caramel slice - To make a beautiful white chocolate slice you can substitute the milk chocolate for white chocolate.
    • Gluten free Billionaires shortbread - To make billionaires caramel slice just add ½ teaspoon of sea salt to the caramel mixture during the cooking process for a gluten free salted caramel slice. Then top with dark chocolate and sprinkle with a little sea salt to finish.
    • Gluten free no bake caramel slice - If you want a quick and easy no bake base that means you dont have to put on the oven. You can use my gluten free biscuit base used in my gluten free banoffee pie in place of the shortbread base. Always use a gluten free cookie base to ensure that you make the caramel slice gluten free.

    Recipe FAQs
