Different yes, deliciously addictive…definitely yes! A classic twist on white chocolate blondies, these are a must have. Chewy, indulgent and the sweetness and sourness go hand in hand.
Blondie anyone? Yes please! In my view you just can’t beat a blondie. Especially a gluten free rhubarb and custard blondie! I think they’re so underrated and they’re by far one of my favourite bakes. Crispy on the top, gooey in the middle. Perfect.
As said above, they’re horribly addictive so watch out if you have no willpower. Even if you do end up eating the entire tray because lets face it, everyone has their guilty secrets, it will be totally and utterly worth it.
This is the perfect summer recipe for a naughty dessert or even to eat on their own.
So step by step instructions are below in the recipe and there is a print button at the top if you would like to print it off.
Shopping List
- 300g stewed rhubarb
- 45g caster sugar
- 2-3 tbsp water from the rhubarb after being defrosted
- 200g salted butter
- 3 medium eggs
- 125g gluten free plain flour
- 250g caster sugar
- 70g custard powder
- 1/4 measured tsp xantham gum – only add if your flour doesn’t already contain it
- 100-120g white chocolate chips/chopped white chocolate
I use Doves Farm Freee gluten free flour, I always have done and it’s always been very reliable however you can use another of your choice.
Ensure your custard powder is gluten free, I use Birds myself.
Make sure your chocolate chips are gluten free as well! You don’t want to make the mistake of buying something that’s not safe for you to eat! It’s always best to check the labels when shopping. I like using Molly’s chocolate for baking, it’s cheap, delicious and gluten free of course!
Can this recipe be made dairy free?
Yes you can make this recipe dairy free! You will have to make a few substitutions listed below.
- Use a block of Stork or Flora Plant Butter instead of the dairy butter
- Use dairy free white chocolate chips
Just a note!
When it comes out of the oven the outer edges should seem crispy and the centre just a little wobbly. If it’s all liquid however, it needs longer baking! Make sure you leave it to cool in the tin with no picking at it! It will continue to set more whilst it cools.
If you enjoy this recipe I’ll be very grateful if you give me a star rating!
On with the baking then…
Gluten Free Rhubarb and Custard Blondies
Equipment
- 1 23cm squared baking tray or one equal to
- 1 wire rack
- 1 electric handmixer
Ingredients
FOR THE STEWED RHUBARB
- 300 g rhubarb
- 45 g caster sugar
- 2-3 tbsp water from the rhubarb after being defrosted or use 2 tbsp water if using fresh rhubarb
FOR THE BLONDIE
- 200 g salted butter
- 3 eggs
- 125 g gluten free plain flour
- 250 g caster sugar
- 70 g custard powder sieved
- 1/4 tsp xantham gum add only if flour doesn't already contain it
- 100-120 g white chocolate chips or chopped chocolate
Instructions
FOR THE STEWED RHUBARB
- Chop the rhubarb up and place in a saucepan with the sugar and water.
- Cook over a medium heat for 5 minutes stirring every now and then. You can place a lid on for it to cook quicker.
- Once mostly stewed down, turn off the heat and leave to cool.
FIOR THE BLONDIES
- Preheat the oven to 180℃/160℃ Fan. Line a baking 23cm baking tray with greaseproof paper. Make sure some overhangs the tray.
- Melt your butter in a saucepan on a low heat and add to a large bowl with the rest of the caster sugar. Beat until smooth.
- Add the eggs one at a time and beat well between each addition.
- Add the gluten free plain flour in 3 lots and thoroughly beat in between each addition.
- Sieve your custard powder and xantham gum into the batter and beat once more.
- Fold in the white chocolate chips and pour into the baking tray.
- Evenly dollop spoonfuls of stewed rhubarb on top until it's all used up and place in the oven to bake for 35-50 minutes. The cooking time may vary depending on your oven.
- Once fully baked remove from the oven and leave to fully cool in the tray. It carries on cooking after being baked so you need it to cool completely and set before cutting up I'm afraid!
- Once cooled completely you can cut the blondie up and enjoy with a good cup of tea!
