04In another bowl, combine the sour cream, butter, heavy cream, the remaining bacon, 1/4 cup Parmesan, 2 tablespoons chives and 1/4 teaspoon salt. Set aside.05When the potatoes are cool enough to handle but still warm, cut off the top third of each potato. Remove the skin from the tops. Using a 1 teaspoon measure or a melon baller, scoop out some of the insides of the cooked potatoes, leaving 1/4-inch borders around the edges. This creates little boats. Place the scooped insides and the peeled tops of the potatoes in a medium bowl and mash using a potato masher or the back of a fork. Add the reserved bacon and sour cream mixture. Using a rubber spatula, mix together the filling until well combine. Spoon the filling back into the potato boats until slightly overfilled and mounded on top. Top with a sprinkling of the panko mixture and a drizzle of olive oil. Bake until the filling is heated through and the topping is golden brown, 10 to 12 minutes. Serve warm or at room temperature.
