Ingredients
  

  • 1 cup all-purpose flour
  • 3/4 cup white whole wheat flour (or use all all-purpose)
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon fine sea salt
  • 2 large eggs, room temperature
  • 1/3 cup maple syrup
  • 1/3 cup cane sugar (or coconut sugar)
  • 1/4 cup olive oil or avocado oil
  • 3/4 cup low-fat milk (2% or almond milk)
  • 2 teaspoons pure vanilla extract
  • 1 teaspoon lemon zest (optional, brightens flavor)
  • 2 large egg yolks
  • 2 tablespoons cornstarch
  • 1/4 cup maple syrup or honey
  • 1 cup low-fat milk (2% works best)
  • 1/2 cup plain 2% Greek yogurt
  • 1 teaspoon pure vanilla extract
  • Pinch of fine sea salt
  • 3 ounces dark chocolate (60–70% cacao), finely chopped
  • 1/3 cup low-fat milk (or unsweetened almond milk)
  • 1 tablespoon butter or coconut oil
  • 1 teaspoon pure vanilla extract
  • Pinch of sea salt

Method
 

  1. Prep the pans and oven: Heat the oven to 350°F (175°C). Grease and line the bottoms of two 8-inch round cake pans with parchment.
  2. Whisk dry ingredients: In a bowl, whisk the all-purpose flour, white whole wheat flour, baking powder, and salt.
  3. Mix wet ingredients: In a separate bowl, whisk eggs, maple syrup, sugar, oil, milk, vanilla, and lemon zest (if using) until smooth.
  4. Combine and pour: Add dry ingredients to wet and stir just until no dry streaks remain. Don’t overmix. Divide the batter evenly between the pans.
  5. Bake: Bake 18–22 minutes, until the centers spring back and a toothpick comes out clean. Cool in pans 10 minutes, then turn out onto a rack to cool completely.
  6. Make the custard: In a saucepan off heat, whisk egg yolks, cornstarch, maple syrup, and a splash of the milk until smooth. Whisk in the remaining milk, salt, and vanilla. Cook over medium heat, whisking constantly, until it thickens and gently bubbles, 4–6 minutes. Remove from heat and whisk in Greek yogurt. Press plastic wrap onto the surface and chill until cold.
  7. Make the glaze: Warm milk and butter in a small saucepan until steaming. Remove from heat, add chopped chocolate, and let sit 2 minutes. Stir until glossy and smooth. Add vanilla and a pinch of salt. Let cool 5–10 minutes to thicken slightly.
  8. Assemble: Place one cake layer on a serving plate. Spread the chilled custard evenly to the edges. Top with the second cake layer.
  9. Glaze: Pour the chocolate glaze over the top and gently coax it to the edges with an offset spatula, letting a little drip down the sides.
  10. Set and serve: Refrigerate 30–45 minutes to set the custard and glaze for cleaner slices. Slice with a sharp knife, wiping between cuts.
