This easy Plum Crumble recipe is the perfect summer dessert recipe to make the most of plum season! Seasonal, juicy plums with a twist of amaretto for a marzipan-like flavour, topped with a buttery, gluten free crumble topping. Perfect comfort food served with vanilla ice-cream or custard.
This Gluten Free Plum Crumble with amaretto is the absolute dream. It’s warming, delicious, a little bit cheeky and the perfect dessert to serve in summer or fall.
Nobody will ever know the crumble topping is gluten free – and trust me, gluten free flour makes the BEST crumble topping!
You’ll find plums at their best in the UK from August to September, while in the US plum season tends to run from May to October.
I like to use ripe plums for this recipe to add to the sweetness – I tend to buy ‘ripen at home’ punnets a few days before I want to make this so they’re perfect come baking time.
If plums aren’t quite in season when you stumble across this recipe, I do have more delicious gluten free crumble recipes for you.

Ingredients
There’s a printable recipe card for this gluten free plum crumble below. But for the shopping list you will need…
For the gluten free crumble topping:
- Caster Sugar: Or baker’s sugar in the US. You can use light brown sugar if you prefer.
- Butter: I use cold, unsalted butter in this crumble topping recipe. Swap for a vegan option if you need dairy free.
- Gluten Free Self Raising Flour: If you can’t find a self rising flour, simply mix 1 teaspoon gluten free baking powder per 100g gluten free plain or all purpose flour.
For the plum crumble filling:
- Plums: Fresh plums are best for this recipe. You want them to be ripe, but not so ripe they go soft and mushy.
- Brown Sugar
- Ground Cinnamon
- Amaretto: For an alcohol free version, you could swap this for 1/2 tsp almond extract. Or just omit it entirely for a plum crumble without the marzipan taste.
How to make plum crumble
There’s a printable recipe card below with the method. But here are some step-by-step photos to show you how easy this gluten free plum crumble is to make:
Firstly, preheat the oven to 180’C / Fan 160’C / Gas Mark 4. You’ll need a 20cm ovenproof dish or cast iron skillet to make your crumble in.
In a large bowl place the plum halves, sugar, cinnamon and amaretto. Mix well until the plums are evenly coated and then pour evenly into an ovenproof dish (approx 20cm diameter). Set to one side.
In a separate mixing bowl add the caster sugar and gluten free self-raising flour. Cut the cold butter into cubes and add to the dry ingredients.
Use your fingertips to rub the mixture together until it starts to form a breadcrumb-like, lumpy consistency.
Some bigger lumps are good as they add a lovely crunch to the crumble. Try not to squish it together into one big mass – just gently use your fingertips, not your whole hand!
TOP TIP: If you struggle to use your hands (or don’t want to get messy!) you can also blitz this in a food processor until it forms a breadcrumb-like texture too.
Pour the crumble mixture evenly over the plums, ensuring they are completely covered.
Place the crumble in the oven for 35-40 minutes until golden brown on top. Remove from the oven and sit for 10-15 minutes before serving hot.
Storing and Freezing
Got any leftover plum crumble? Here’s what to do with your remaining plum crumble:
To store: Pop any leftovers in the fridge for 1-2 days. Any longer and you may find the crumble starts to absorb the juice from the plum filling and go soft.
I recommend reheating any leftover plum crumble in the oven before eating – the microwave may cause the crumble top to go soggy.
To freeze: Can you freeze plum crumble? Yes, you can! Cool the crumble completely, portion into tubs and then freeze for up to 6 months. Reheat in the oven before eating.
