This bakery-style crumble topping features browned-butter magic and a hint of cinnamon for a golden, crunchy texture that elevates any fruit crisp, muffin, or dessert.
In a medium bowl, whisk the all-purpose flour, light brown sugar, baking powder, ground cinnamon (optional), and salt until the color looks even and you do not see sugar clumps hiding in the corners.
Use your fingertips to break any stubborn brown sugar nuggets. The mixture should look sandy and uniform with a cozy cinnamon scent.
Add the butter and build crumbs
Drizzle in the melted and cooled unsalted butter. Start tossing the mixture with a fork so the flour coats the butter instead of turning greasy.
Keep mixing just until moist crumbs form. You should see a mix of pea-sized bits and bigger marble-like clumps that hold together when pinched.
Chill until you need it
For the best results, let the mixture rest for 10 minutes to allow the flour to hydrate. This helps the clumps stay sturdy when baked.
Spoon the crumble topping into an airtight container and refrigerate for up to 5 days. It will firm up and be easy to sprinkle in generous clumps whenever dessert calls.
Notes
Safety Tip: Because this topping contains raw flour, avoid tasting the mixture before it is fully baked.Pro Tip: Ensure the melted butter is cooled slightly before mixing. Using butter that is too warm will dissolve the sugar and prevent those beautiful, distinct clumps from forming.Storage Tip: You can freeze the raw crumble in an airtight bag for up to 3 months. Sprinkle it directly from frozen onto your desserts to help the topping stay extra crunchy.Nutrition information is estimated based on common ingredients and serving sizes and may vary.
