With an electric mixer on medium-high speed, cream butter and 1 cup sugar until pale and fluffy. Add eggs, one at a time, beating until each is incorporated, scraping down sides of bowl as needed. Beat in vanilla extract. Reduce speed to low. Add flour mixture in two batches, alternating with the sour cream, and beating until combined after each. Stir in 2 cups diced rhubarb. |

Divide batter evenly among lined cups, filling each three-quarters full. Bake, rotating tins halfway through, until a cake tester inserted in centers comes out clean, about 25 minutes. Transfer tins to wire racks to cool completely before removing cupcakes. Cupcakes can be stored up to 3 days at room temperature in airtight containers; remove liners before topping. |

To make rhubarb topping, use the tip of a paring knife to scrape vanilla-bean seeds into a saucepan, reserving pod for another use (such as vanilla sugar). Add the water and remaining 1 cup sugar, and bring to a simmer, stirring to dissolve sugar. Remove from heat, and stir in remaining 1 cup rhubarb. Let cool completely. Remove rhubarb with a slotted spoon, and reserve. Return liquid to a simmer, and cook until reduced by half, 5 to 8 minutes. Let cool slightly, then return rhubarb to syrup. Once cool, rhubarb can be refrigerated in syrup up to 1 week in an airtight container; bring to room temperature before using. |
