1. Preheat your oven to 350 degrees F. This temperature is essential for creating the perfect crumb texture that will be both crisp and tender.
2. In a medium bowl, take the strawberry flavored Jell-o and mix it with 1/2 cup of flour and 1/4 cup of butter using a fork. Stir until the mixture resembles a crumble.
3. In another medium bowl, combine the remaining 1/2 cup of flour, 1/2 cup of sugar, and 1/4 cup of butter. Add 1 teaspoon of vanilla. Mix these ingredients until they form another crumbly mixture.
4. Prepare your baking sheet by lining it with parchment paper. This step is crucial to ensure the crumbs do not stick to the pan.
5. Now, sprinkle the strawberry crumbles evenly onto the baking sheet. Follow this by adding the vanilla crumbles.
6. Bake the mixture for 7 to 8 minutes. Watch carefully; you don't want them to brown too much.
7. Once baked, remove the baking sheet from the oven and allow the crumbles to cool completely.
8. After cooling, store the crumbs in an airtight container in the fridge.
