Millionaire’s shortbread is one of my favourite treats to enjoy with an afternoon cup of coffee, and when I stumbled across a banoffee version on Pinterest from deliciousmagazine.co.uk, I knew that I had to make vegan version! So here it is, layers of gluten-free shortbread, sliced creamy bananas, decadent peanut butter caramel and a thick chunk of chocolate – heaven!

The original recipe used a caramel that was based on condensed milk, and instead of going down the condensed coconut milk route I decided to make a nut butter caramel. That means there’s no boiling and waiting for it to cook, it’s just a matter of blending up the peanut butter with a few other ingredients and you have an instant caramel layer.

WHAT INGREDIENTS WILL I NEED TO MAKE THIS MILLIONAIRE’S SHORTBREAD?

To make the shortbread base, you’ll need the following:

Gluten free all purpose flour: The best gluten-free flour to use will be made up of a blend of several flours such as rice flour, millet flour, tapioca starch and xanthan gum. It will vary depending on what brand you use, but the most important thing is to go with a blend, not a single ingredient flour. If you’d like to take a crack at making your own, check out the recipe for homemade gluten-free all purpose flour on crowdedkitchen.com. You can of course also use regular all purpose flour if you don’t need the recipe to be gluten-free.

Ground almonds: Ground almonds, or almond flour is used to make the shortbread along with the all purpose flour at a ratio of 50:50.

Vegan butter: Traditional shortbread uses a lot of butter and dairy. The base of this millionaire’s shortbread comes together with plant-based butter, and uses just a fraction of the butter you’ll find in conventional recipes. You can also substitute the butter for solid coconut oil if preferred.

Pure maple syrup: The liquid sweetener for the shortbread, you can also use agave syrup.

You’ll also need a pinch of sea salt.

For the filling and topping you’ll need:

Bananas: You’ll need ripe bananas, but not mushy discoloured ones as they will need to hold their shape well when cut.

Lemon juice: This stops the bananas from discolouring and increases their shelf life a little!

Peanut butter: The main ingredient for the caramel layer. You can use any nut butter of your choice for this part, I find that the peanut butter works really well with chocolate and banana. Cashew butter, almond butter or even sunflower butter would work well too!

Coconut oil and canned full fat coconut milk: As well as creating a rich and creamy caramel, coconut milk and coconut oil solidify when chilled which helps the caramel to set and keep it’s shape when cut.

Vanilla extract: This adds more flavour and depth to the caramel layer and pairs really well with the banana and peanut butter.

Vegan chocolate: You can use vegan milk chocolate or dark chocolate depending on your taste.

THE SHORTBREAD BASE

The shortbread for this traybake could not be easier. There’s no kneading or chilling required which makes it a super quick pastry to prepare. You’ll simply chuck all of the ingredients into your food processor and let it do all the work. It’ll just take a minute or so of blitzing and the ingredients will come together to form a shortbread dough.

Next you’ll press the shortbread into the base of an 8×8″ pan lined with some parchment paper. I like to use the base of a flat bottomed glass to help smooth out the pastry and get a nice even layer.

Once the base is compact and even, use a fork to prick several holes into the shortbread before transferring it to an oven that’s been preheated to 175°C (350°F).

BANANA LAYER

Slice the bananas into coins about 1cm in height. Then transfer them to a shallow bowl with lemon juice in it. Coat all sides of the banana coins in the juice before laying them on a paper towel or kitchen towel. Gently blot off any excess moisture to make sure that they don’t weep liquid into your perfectly baked shortbread crust.

Carefully arrange the banana coins on top of the shortbread in an even layer. Cut the coins to size for the edges if needed (see image below)

PEANUT BUTTER CARAMEL

The caramel is super easy to make, just like the shortbread dough, all you need to do is add all of the ingredients to your food processor and blend until smooth. Once you have a silky smooth caramel consistency, carefully transfer the caramel to the baking tin on top of the banana slices. Use a spatula to spread it out evenly, be cautious not to press down too hard as you may dislodge the banana coins if you’re too rough!

Next it goes into the fridge to chill for at least 2 hours, although it works really well if you want to leave it set in there overnight.

CHOCOLATE COATING

Melt the chocolate over a double boiler and use a spatula to spread it over the caramel in an even layer.

double boiler consists of a water bath made using a saucepan which is filled about quarter ways with water. The saucepan is placed on a low-medium heat so that the water is brought to a gentle simmer. The chocolate is then added to a heat resistant bowl (which covers the entire circumference of the saucepan), and the steam that rises from the simmering water will gently melt the chocolate. It’s important not to apply direct heat to chocolate as it will burn, also, make sure you avoid water splashing into the bowl at all costs as this will cause the chocolate to seize.

Place in the fridge for 15 minutes to set and then slice! (find out how to get the perfect cuts further down under “recipe tips”)

HOW TO GET THE PERFECT CUTS

  1. Use a knife and measuring tape to evenly mark out your cuts.
  2. Place a sharp knife in a jug of boiling water for a couple of minutes to heat it up.
  3. Wipe the knife dry and gently slice into the traybake, using the pre-marked cuts as your guide. Allow the heat of the knife to do the work and melt through the chocolate layer, without applying too much pressure.
  4. Cut one slice at a time, and reheat the knife in between slices.
  5.  

HOW TO STOP BANANAS FROM DISCOLOURING

One problem with using fresh bananas is they tend to discolour when exposed to oxygen in the air. But, when you add a little squeeze of lemon juice, magic happens! Your banana slices will keep their original colour and the taste won’t be affected. Lemon juice contains citric acid which alters the enzymes in banana and prevents enzymatic discolouration. You can also use lime juice in place of lemon if you have it handy.

HOW TO STORE YOUR BANOFFEE MILLIONAIRE’S SLICES

To get the best out of your shortbread treats, store them in an airtight container and refrigerate. Because they contain fresh banana, these bars are best enjoyed within 2 days, maybe 3 at a push!
