Struesel Topping

Store in an airtight container. If storing at room temperature, ensure it's completely cooled and dry.

For extra flavor and texture, add chopped nuts like pecans or walnuts to your streusel mixture.

Don't overmix the streusel; you want distinct crumbles, not a paste.

Chill the streusel mixture before topping your baked goods for a crisper result.

For a spicier kick, increase the amount of cinnamon or add a pinch of nutmeg or cardamom.
