At this time of year we love to go blackberry picking in our local area. Picking wild blackberries is an easy peasy way to keep the children entertained for an hour or so and we love making goodies with our blackberry haul. This recipe was born as a result of one of these blackberry pickings during blackberry season. These blackberry oat bars are soft, really tasty and naturally sweet and full of protein and goodness - you can't not love them!
These blackberry oatmeal bars are a perfect late summer / autumn snack, whenever you find that blackberries are in season and something different for school bake sales.

You can also use frozen blackberries so if you find that you have some left from your blackberry picking endeavours you can pop them in a freezer bag and freeze for up to three months. They will just need a little bit of extra cooking time when you are making the blackberry layer. See below for more tips for making this with frozen blackberries.
This recipe is quite similar to my vegan raspberry flapjacks on this site, and pairs well warmed up and served with vegan cream.
Ingredients
You will need a few ingredients for this recipe. Most of them are store cupboard ingredients so hopefully you have most of them in the house already. There is nothing artificial in these oat bars and they are full of the goodness of natural ingredients and naturally sweetened by the fruit and maple syrup. Oats and almonds provide protein and make these not only delicious but filling too.

- Oats
- Ground almonds
- Coconut oil
- Maple syrup
- Apples
- Blackberries
- Ground cinnamon
- Chia seeds
- Flaked almonds
See recipe card for exact quantities.

Instructions
Grease and line a 9 x 9 baking tin with parchment paper and pre-heat the oven to 180 degrees celsius.
Start off by making the oat layer. Blitz the oats in a food processor to turn them into an oat flour. Mix this with the maple syrup, coconut oil and ground almonds. Divide this mixture into two, one 400g portion and another 200g portion. Set the 200g portion aside in a large mixing bowl for later and press the 400g portion into the base of your baking tin. Press it down using the back of a spoon or the bottom of a glass. Pop into the oven for 15 minutes or until starting to turn golden brown. Remove and leave to cool.

Next you will need to make the blackberry layer. Peel and finely chop 150g of apples (approx 2 medium apples). Put the cubed apple with the blackberries, maple syrup, cinnamon and chia seeds into a medium saucepan and cook over a medium heat, stirring often until the mixture thickens. Set aside to cool.
Top tip: Make sure to cut the apples into small pieces or otherwise the blackberry layer will be too chunky. Also you should keep an eye on this while it is cooking so that it doesn't overcook.
In the other bowl add cinnamon and flaked almonds to the remaining crumble mixture. Stir to combine.
When the base layer is cool spread the blackberry mixture over the top in an even layer and then sprinkle the oat and almond mixture over the top.
Bake for 20 minutes until starting to brown. Allow to cool completely in the tin before slicing into 12 portions.
Hint: Use a loose bottomed square baking tin for making these, it will help you to remove them without them crumbling or breaking.

FAQs
How do I store these apple crumble bars?
These oat bars are best eaten warm out of the oven but they will keep in an airtight sealed container at room temperature or in a cool place for 2-3 days. Because of the fruit content these are best eaten sooner rather than later, although that's not a problem in our house!
Can I use frozen blackberries for this recipe?
Yes, you can typically use frozen blackberries for a vegan apple and blackberry crumble bars recipe. However, there are a few things to keep in mind.
Thawing: If you're using frozen blackberries, it's a good idea to thaw them first. You can do this by placing them in a strainer over a small mixing bowl to allow excess moisture to drain. You can also pat them dry with a paper towel to remove excess water. This helps prevent the excess moisture from making the filling too runny.
Adjust for Moisture: Because frozen blackberries can release more moisture during baking, you might need to adjust the recipe slightly. You can add a bit more thickener (like cornstarch or tapioca) to the fruit filling to help absorb the extra liquid.
Taste Test: Depending on the quality and sweetness of your frozen blackberries, you may need to adjust the sugar in the recipe to suit your taste.
By following these steps, you can successfully use frozen blackberries in your vegan apple and blackberry crumble bars and still enjoy a delicious dessert.
Can I use other fruits instead of apples and blackberries in this recipe?
Certainly, you can experiment with other fruits to create unique variations of vegan crumble bars. Here are some fruit options you can substitute for apples and blackberries in a vegan crumble bars recipe.
Mixed Berry Crumble Bars: Try a fruit mixture - a combination of raspberries, blueberries, and strawberries for a colorful and tangy twist.
Peach and Raspberry Crumble Bars: Peaches and raspberries offer a delightful balance of sweetness and tartness.
Cherry Almond Crumble Bars: Use sweet or sour cherries with almond extract for a delicious cherry-almond flavor.
Mango and Pineapple Crumble Bars: Opt for a tropical twist with diced mango and pineapple for a sweet and tangy result.
Pear and Cranberry Crumble Bars: Combine the subtle sweetness of pears with the zing of cranberries for a flavorful, wintery treat.
Strawberry Rhubarb Crumble Bars: Pair strawberries with rhubarb for a classic and slightly tart flavor combination.
Banana and Blueberry Crumble Bars: Ripe mashed bananas and blueberries offer a creamy and fruity crumble bar experience.
Feel free to get creative and use fruits that you enjoy or have on hand. Just be aware that different fruits may require adjustments to sugar and thickener quantities to suit your taste and maintain the desired texture.
