Carrot Oat Ginger Cakes

  1. In a large bowl, stir together oil, honey, yogurt, eggs and ginger. Stir in carrots.
  2. In a smaller bowl, whisk together oats, flour, baking powder, baking soda, cinnamon and salt.
  3. Add the dry ingredients to the wet, folding together until combined.
  4. Allow the batter to rest for 30 minutes.
  5. Using a 1/4 cup scoop, drop cakes onto a parchment-lined cookie sheet. Do not flatten the batter.
  6. Bake at 375°F (190°C) for 15 minutes, or until a toothpick inserted in the center comes out clean.

Cream Cheese Filling

  1. Whip cream cheese and butter until smooth.
  2. Add powdered sugar, one half-cup at a time, beating well after each addition. Beat in vanilla.

To Assemble

  1. Cool cakes completely before assembling.
  2. Spread a generous dollop of filling on the bottom (flat side) of one cake. Carefully place a second cake on top (flat side toward filling), pressing halves together gently.
  3. Serve at room temperature, or chill to firm up filling.
