First things first, get those apples peeled, cored, and sliced – about half an inch thick is what I aim for. Then, toss them into a big bowl with your mixed berries, granulated sugar, flour, and a good squeeze of fresh lemon juice. Give it a gentle mix; you want everything coated but not bruised. I often find myself taking a sneaky bite of the fresh fruit here, oops!

Now for the fun part! In another bowl, combine the rolled oats, brown sugar, more flour, ground cinnamon, and that pinch of salt. Give it a whisk to combine. Then, cut your very cold butter into small cubes and add them in. Use your fingertips or a pastry blender to work the butter into the dry ingredients until it looks like coarse crumbs with some pea-sized pieces. This is where I always make a bit of a mess, but it’s worth it!

Pour your fruit mixture into a 9x13 inch baking dish. Make sure it's spread out evenly. It should smell wonderfully fruity already, even before baking! I usually use a glass dish, but honestly, any oven-safe dish works. Don't overfill it, or you'll have bubbling fruit everywhere, and trust me, that's a cleanup you want to avoid.

Generously sprinkle that glorious oat crumble topping all over the fruit. Don't press it down; we want air for maximum crispiness! This is where you can be a little artistic, making sure every juicy fruit bit gets covered. I sometimes leave a few bigger clumps of topping because, let's be real, those are the best bits, aren't they?

Pop your crumble into a preheated oven at 375°F (190°C). Bake for about 40-50 minutes, or until the topping is beautifully golden brown and the fruit is bubbling away underneath. You'll smell it when it's ready, trust me! I always set a timer, but then find myself peeking through the oven door every five minutes, honestly, I can't help it.

Once it's out of the oven, let it cool for at least 15-20 minutes before serving. This allows the fruit filling to set up a bit, preventing a watery mess. It will still be wonderfully warm. The aroma filling your kitchen right now? That's pure magic. Serve it warm with a scoop of vanilla ice cream or a dollop of whipped cream – pure bliss!
