Preheat the oven to 350°F (180°C, or gas mark 4).

Prepare a large rimmed baking sheet.

In a microwave-safe bowl, combine peanut butter, sugar, and water.

Heat in the microwave for 30–60 seconds to soften the peanut butter.

Mix in 20 g (2 tablespoons) of the brown rice flour, cinnamon, salt, and oats.

The mixture will become thick.

Transfer the mixture to the baking sheet and combine with your fingers, working it into chunks.

Sprinkle the remaining 20 g (2 tablespoons) of brown rice flour on top and gently work it in, taking care not to break the granola chunks too much.

Add the jam in small dollops, distributing it throughout the granola without fully coating it.

Spread the mixture evenly across the baking sheet.

Bake for 8 minutes, then stir well.

Bake for an additional 10 minutes, or until golden brown.

Allow to cool completely on the baking sheet before transferring to an airtight container.

Store in the refrigerator once cooled.
