How to Bake a Rich Chocolate Cake with Hidden Zucchini

Step 1: Prepare Oven and Pans

Warm up the oven to 350°F (180°C). Grease two 8-inch cake pans thoroughly with cooking spray or butter.

Step 2: Create Buttermilk Substitute

In a small bowl, combine:
  • Milk
  • Vinegar

Whisk together and let sit for 5 minutes to create a buttermilk-like mixture.

Step 3: Mix Dry Ingredients

In a large mixing bowl, combine:
  • Oat flour
  • Cocoa powder
  • Arrowroot powder
  • Baking soda
  • Baking powder

Stir ingredients until well blended.

Step 4: Combine Wet Ingredients

In a separate bowl, whisk together:
  • Buttermilk mixture
  • Brown sugar
  • Applesauce

Blend until smooth and creamy.

Step 5: Create Cake Batter

Pour wet ingredients into dry ingredients. Stir gently until just combined. Fold in shredded zucchini with a light touch.

Step 6: Fill Cake Pans

Divide batter evenly between the two prepared cake pans, spreading smoothly.

Step 7: Bake the Cake

Place pans in preheated oven. Bake for 35-40 minutes. Check doneness by inserting a skewer into cake center- it should come out clean.

Step 8: Cool the Cake

Remove cakes from oven. Let cool completely inside the pans.

Step 9: Frost and Serve

Apply chocolate frosting between layers and on top and sides of cake. Slice and enjoy your delicious zucchini chocolate cake!

Tips for Getting Moisture and Richness Just Right

  • Squeeze Out Moisture: Grate zucchini and use a clean kitchen towel to remove excess water, preventing a soggy cake texture.
  • Gentle Mixing Technique: Stir wet and dry ingredients just until combined to maintain a tender, light cake crumb.
  • Even Baking Trick: Rotate cake pans halfway through baking to ensure uniform heat distribution and consistent browning.
  • Cooling Crucial Step: Let cakes cool completely in pans to prevent breaking or crumbling when removing and frosting.
  • Flavor Boost: Add a dash of cinnamon or espresso powder to enhance the chocolate's depth and complexity.

Storing and Reheating This Unexpected Chocolate Gem

  • Refrigerate: Wrap the cake tightly in plastic wrap or store in an airtight container. Keep in the refrigerator for up to 5 days to maintain moisture and freshness.
  • Freeze: Slice the cake, place parchment paper between layers, and store in a freezer-safe container. Freeze for up to 3 months for longer preservation.
  • Reheat: Thaw frozen cake slices in the refrigerator overnight. Warm individual pieces in the microwave for 15-20 seconds, or let sit at room temperature for 30 minutes before serving to restore soft texture.
