Streusel is a crumbly mixture of flour, butter, and sugar. Streusel topping is most commonly used on fruit pies, a crisp, or a crumble, and should be added right before the pie goes into the oven. It can also be used to top muffins, batter breads, and cakes.

Overview

  • Skill Level: Beginner

This basic streusel topping can be used to top numerous baked goods such as pies, cakes, muffins, and sweet breads. A streusel creates a sweet and crumbly texture that elevates simple recipes.

The recipe, in it’s most simple form, contains very few ingredients: flour, sugar, and butter. However, spices and chopped nuts can be added if desired.

Ingredient Functions

  • Brown Sugar adds sweetness and a rich flavor to the streusel topping due to the molasses present in it. The brown sugar also helps to add moisture to the topping. If you want more crunch and texture to your streusel topping, you can use all granulated sugar instead of the combination of brown sugar and granulated sugar.
  • Granulated Sugar adds more sweetness and helps the streusel topping crisp up slightly once it is baked. This adds a nice texture to the top of your baked good.
  • All-Purpose Flour is used in a small amount to help bind the mixture together and give it a crumbly texture. A gluten free baking blend will work well as a replacement if you need to make a gluten free streusel.
  • Cinnamon is an optional ingredient but works well for most streusel uses. Cinnamon’s only function is flavor and can be left out completely or substituted with other spices if desired.
  • Salt rounds out and balances the sweet flavor.
  • Butter coats the mixture in fat to help create the crumbly texture by adding moisture. Without the fat, the streusel mixture would be extremely dry and unpalatable after baked. Vegan butter substitutes can be used in place of real butter.

Tips, Tricks, and Techniques

There are very few basic steps to creating a streusel topping. All of the ingredients, except the butter, are stirred together.

Melted butter is then added to the mixture and coated over the dry ingredients.

The streusel topping can be made up to three days ahead of time and kept in an airtight container in the refrigerator until ready for use. Use streusel to spruce up a simple recipe, such as a topping for blueberry muffins, coffee cake, or even on a basic banana bread.

How to bake streusel topping

If you’re adding streusel on top of an unbaked batter like you would for muffins or banana bread, then you don’t need to bake the streusel topping separately. It will bake in the oven while the bread bakes.

If you plan to use the streusel as a layer in a cake trifle or as a topping over yogurt or ice cream, then you need to bake the streusel topping separately.

How to bake

After mixing up the topping, spread it out in an even layer on a parchment lined baking sheet. Bake on 350°F/175°C for about 8-12 minutes until browned. After cooling, break it up with your hands to make crumbles. Store in an airtight container at room temperature for 3-4 days.
