Rhubarb Crumble 🤤

This is such a comforting classic and works so well in the air fryer! The tangy rhubarb balances perfectly with the buttery, crunchy topping, and it’s ready in no time. I usually make mine using both drawers of my air fryer, but if you only have a single drawer, you can warm the rhubarb on the hob while the crumble topping cooks. I cook the crumble and rhubarb separately so the topping is nice and crispy. This works really well with tinned apples too 🍎
