Metis® Fruit and Maple Crumble Bars

These Metis® fruit and maple crumble bars make for a perfect summer dessert or sweet treat. With a delicious layer of sweet Metis® fruit and maple jam sandwiched between a soft buttery crumble.

They’re totally addictive so be careful who you share them with!

Let’s start with the jam. The jam is made up with Metis® stone fruit, a natural cross between a plum and apricot. For this recipe I’m using Oxy Solar.

It has a dark purple skin and super juicy sweet flesh which make it perfect for baked goods, in this case, crumble bars! There are also three other family members – Dark Moon, Safari Star and Sunset Sky. Find out all about them here!

For the jam you’ll need a few simple ingredients. Metis® fruit, maple syrup, lemon juice, vanilla and cornstarch. Carefully pit the Metis® and place in a pot on medium heat with the other ingredients.

Let this simmer until the fruit has broken down and the jam has thickened, it will take about half an hour.

Whilst the jam is cooking you can prepare your crumble. You don’t need to make a different crumble base to the topping, making this super simple!

I like to use a food processor to make the crumble, it means you don’t need to get more utensils dirty, which is always a no brainer for me!

Blitz the oats along with soft brown sugar, baking powder and flour until it turns into an oat flour consistency. Add vegan butter and blitz again until well combined and it is starting to clump.

That’s it, you’ve made your crumble. Told you it was easy, and quick! For the base, we are going to use 2/3 of the crumble.

Grease and line an 8×8 inch cake tin and use a spoon or your fingers to push the mixture into the tin until you have an even layer. Bake for 10 minutes.

Once the base has baked it’s time to assemble the jam and the remaining crumble mixture. Using your hands, crumble it between your fingers on top of the jam.

Place in the oven for 25-30 minutes. The crumble topping should be golden brown.

You’re going to need to leave the crumble bars to completely cool before cutting into them. Which means leaving them in the fridge to set for a couple of hours.

If you’re anything like me, you’ll have little patience waiting for baked goods to cool out the oven. So, I give you full permission to also just dig in with a fork and eat it warm out the tin.

Hopefully you’re on your way to the shops or the kitchen so start making these Metis® fruit and maple bars. Trust me when I say they’re irresistible!

Whilst these crumble bars are delicious on their own, they also pair nicely with some vegan ice cream or custard! I’ll leave that decision with you.

If you want to get your hands on Metis® fruit head to Co-op, Tesco, Morrisons, M&S or Costco. They will be available all summer and you’ll find them in the fresh fruit section!

Look out for the Metis® sticker on packs of plums and pick up a couple of packs! To make these crumble bars, of course.
