Crumb Topping for Cakes
Perfect for bundt cakes, coffee cakes, apple cake …did I mention cake? This buttery cinnamon-brown sugar crumb topping adds the perfect sweet, crunchy finish to any cake that needs a little extra love.

Ingredients

1 topping servings
  • 1/2 cup flour
  • 1/2 teaspoon cinnamon
  • 1/2 cup brown sugar
  • 4 tablespoon softened butter

Step-by-Step Instructions

  1. For the crumb topping, mix the softened butter with flour, cinnamon, and brown sugar using a fork or your fingers until crumbs form. The mixture should resemble coarse crumbs.
  2. Sprinkle crumbs evenly on top of your cake batter before baking. Bake cake according to the recipe’s directions. Works wonderfully on bundt cakes, coffee cakes, or apple cake.

Common Problems and Solutions

Q: Why is my crumb topping melting into the cake instead of staying on top?

A: Your butter was likely too soft or melted. The butter should be softened but still hold its shape—about room temperature. If it's too warm, chill the crumb mixture for 10-15 minutes before sprinkling on the batter.

Q: Can I make this ahead of time?

A: Yes! Mix the crumb topping and store it in an airtight container in the refrigerator for up to 3 days, or freeze for up to 3 months. Use straight from the fridge or freezer—no need to bring to room temperature.

Tips and Techniques

Butter should be softened but not melted for the best crumb texture. If it’s too soft, the mixture will clump rather than form nice crumbs. You can use your fingers or a pastry cutter to work the butter into the dry ingredients.
