1. Preheat oven to 400°.
2. Scrub potatoes; pat dry with paper towels. Rub potatoes with olive oil. Place on a foil-lined baking sheet. Bake at 400° for 1 hour and 5 minutes or until tender. Cool slightly on pan.
3. While potatoes cook, combine brown sugar and flour, stirring with a whisk. Cut in butter with a pastry blender or 2 knives until crumbly. Stir in pecans and bacon.
4. Cut potatoes in half lengthwise. Scoop out pulp, leaving a 1/4-inch-thick shell. Place pulp in a food processor. Add granulated sugar and remaining ingredients; process until smooth. Spoon potato mixture evenly into shells; top evenly with brown sugar mixture. Bake at 400° for 20 minutes or until thoroughly heated.
