**The One-Bowl Method for a Cozy Night:**
**Preheat & Prep:** Preheat your oven to 375°F (190°C). Find your favorite baking dish and one large mixing bowl. That’s all you need.
**Fill the Bowl with Apples:** Put all the sliced apples directly into your one bowl. Add sugar, flour, cinnamon, nutmeg, lemon juice, and vanilla. Toss gently with your hands until every slice is coated. You’ll already smell the comfort. Pour this into your baking dish.
**Make the Crumble in The Same Bowl:** Don’t wash it. Add the flour, oats, brown sugar, cinnamon, and salt to the same bowl. Add the cold butter cubes. Use your fingertips to rub the butter into the dry ingredients until it looks like wet, clumpy sand. This is the most therapeutic part.
**Bake the Comfort:** Sprinkle that beautiful, buttery crumble evenly over the apples. Bake for 40-45 minutes, until the top is deep golden brown and you see the apple juices bubbling thickly at the edges.
