What types of berries work best for this jam slice?

You can use fresh or frozen blackberries, boysenberries, mulberries, raspberries, or strawberries, or a mix of any of these, for the jam filling.

How can I ensure the oat base isn't too crumbly to press into the tray?

If the mixture feels too crumbly after combining, simply add a bit of water or your milk of choice until it forms a more cohesive ball.

Why is arrowroot powder added to the berries?

Arrowroot powder helps to thicken the berry mixture during baking, ensuring your jam layer sets nicely within the slice.

Can I prepare the berry jam mixture ahead of time?

The recipe suggests combining the berries, arrowroot powder, and lemon juice right before distributing it over the base layer to ensure optimal thickening during baking.

How should I store leftover Oat and Berry Jam Slices?

After allowing the slices to cool completely, store them in an airtight container at room temperature for a few days, or refrigerate for longer freshness.

How to Prepare Oat and Berry Jam Slice [Vegan]

Preheat oven to 360ºF and line a tray with parchment paper.
In a large bowl, combine ground oats, oats, coconut sugar, butter/coconut oil, and almond butter by hand. Rub the mixture between your fingers until well combined then form a ball with two thirds of the mixture. If too crumbly, simply add a bit of water or milk of choice. Reserve the other third to crumble on top.
Press large ball of mixture into prepared baking tray. Use a rolling pin if necessary.
Place berries into a shallow bowl and combine with arrowroot powder and lemon juice. Use a fork to mash it all together and distribute over base layer. (Don’t worry, it will thicken during baking).
Lastly, crumble remaining oats over jam and bake for 15 - 20 minutes or until golden on top.
Let cool completely before slicing.
