Zucchini Coffee Cake

Gather all ingredients. Preheat oven to 350 degrees F (175 degrees C). Line a 9x13-inch pan with foil and coat with cooking spray.

Using large holes of a box grater, shred zucchini. (You should have 2 cups packed.) Transfer zucchini to a clean kitchen towel. Roll up; squeeze out as much moisture as possible.

Stir together flour, baking powder, and salt in a bowl.

In a large bowl, beat 1 cup softened butter with an electric mixer until light and fluffy.

Gradually beat in sour cream, then white sugar.

Beat in eggs, 1 at a time.

Stir in zucchini and vanilla.

Fold in flour mixture with a spatula, mixing just until incorporated.

Spread batter into prepared pan.

Stir together pecans, brown sugar, and cinnamon in a bowl. Stir in 2 tablespoons melted butter until crumbly.

Sprinkle topper over cake batter.

Bake until a toothpick inserted into center of cake comes out clean, 35 to 40 minutes. Let cool in pan 10 minutes before serving.
