Preheat oven to 350F.
Butter a 9x5 inch loaf pan and set side.
In a medium bowl mix dry ingredients: flour, sugar, baking powder and salt.
In the large bowl of an electric mixer, whisk softened butter on medium speed for 1-2 minutes.
Add dry ingredients and combine with butter for 30-40 seconds.
Add heavy cream, oil, lemon juice, lemon zest and eggs one at a time, mix on medium-high for one minute, until well combined.
In a buttered loaf pan, pour 1/3 on the lemon batter on the bottom of the pan. Start stacking the batman shapes one inch from the front of the pan, stack them thru the length until the end of the loaf pan (see picture at the end of the post). Carefully, pour the remaining batter over the batman shapes and transfer to the oven.
Bake for 25-30 minutes, a tooth stick inserted into the center of the cake must come clean.
Once baked, remove from oven, let it chill, sprinkle with powdered sugar, slice and serve.
