Step 1In a large bowl, whisk together the flour, sugar, baking powder, baking soda and salt. Whisk in the egg, buttermilk and 2 tablespoons olive oil until the batter is smooth, then stir in the chocolate pieces.
Step 2Heat the remaining 2 tablespoons of olive oil in a medium saute pan over medium-low heat. Ladle one-fourth cup of the pancake batter into the pan and cook until golden brown, about 2 minutes. Flip the pancake with a spatula and cook until golden brown on the second side, 1 to 2 more minutes. Place the pancakes in a warm oven until all are cooked and ready to serve. Repeat with the remaining batter, adding more olive oil to the pan as needed.
Step 3To serve, drizzle the pancakes with honey and garnish with mint.
