How To Make a Crumble Topping

This versatile crumble topping starts with real butter—and that’s what makes it so good. Rich, melted butter brings everything together while baking into golden clusters with irresistible crunch. A hint of lemon zest and warm cinnamon brighten the flavor, making this the perfect topping for cheesecakes, ice cream, crisps, or even yogurt parfaits.

Get Started

Step 1: Choose Your Flavors

The cinnamon adds cozy warmth while the lemon zest gives a bright citrus pop—both bring balance to the richness of the butter.

Step 2: Combine Dry Ingredients

In a large bowl, whisk together:
  • 1 cup all-purpose flour
  • 1/3 cup light brown sugar
  • 1/3 cup granulated sugar
  • 1 teaspoon cinnamon
  • 1/2 teaspoon lemon zest
  • 1/4 teaspoon kosher salt

Step 3: Add Melted Butter

Pour in 1/2 cup melted and cooled unsalted butter. Stir with a spoon or spatula until the mixture begins to form clumps.

Step 4: Mix Into Crumbs

Use your hands to gently press and mix until coarse crumbs form. The butter binds the ingredients into sandy, buttery clumps that will crisp up beautifully in the oven.

Step 5: Bake

Spread the crumbs into an even layer on a baking sheet lined with parchment paper. Bake at 350°F for 20–25 minutes, or until the crumble is golden and lightly crisped.

Step 6: Cool & Store

Let the crumble cool completely on a wire rack. Once cool, break into smaller chunks if needed. Store in an airtight container at room temperature for up to 2 days.
