# How-To Steps:

01 - Preheat oven to 350°F. Grease and flour a 9x13-inch baking pan.
02 - Whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg in a bowl.
03 - In a large bowl, beat vegetable oil, granulated sugar, and brown sugar until well combined. Add eggs one at a time, mixing thoroughly. Blend in yogurt and vanilla extract.
04 - Stir in grated zucchini. Gently fold in the dry ingredients until just combined. If desired, incorporate chopped nuts.
05 - Spread batter evenly in the prepared baking pan. Bake for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean.
06 - Allow cake to cool completely in the pan on a wire rack.
07 - In a small saucepan, melt butter over medium heat. Add brown sugar and milk, stirring constantly until sugar dissolves and mixture reaches a gentle boil. Boil gently for 1 minute. Remove from heat and let cool for 5 minutes.
08 - Whisk in powdered sugar and vanilla extract until smooth and spreadable.
09 - Spread icing evenly over cooled cake. Allow icing to set before slicing and serving.

# Expert Hints:

01 -
  • The brown sugar icing melts into each bite like a buttery secret you wont want to share.
  • It stays ridiculously moist for days—assuming it lasts that long on your counter.
02 -
  • If you skip cooling the cake fully, your icing slips off in buttery puddles—patience really pays off here.
  • Switching to a hand whisk for the icing gave me a smoother finish than any mixer ever did.
03 -
  • Lining the pan with parchment makes lifting the cake out a breeze—no more stuck corners.
  • Mix grated zucchini with a pinch of sugar and let it sit for five minutes to release extra moisture before folding in.
