Cream Stuffed Maritozzo made with Nutella^®

In a mixer with a whip attachment, whip cream and 1 tbs. granulated sugar at medium high speed until stiff peaks form.  Place Brioche Buns on a sheet pan and slightly warm them in a 200 degree oven.  When cool, gently slice open each bun from the top, cutting out a “V” shape.  Be careful not to slice all the way through the bun.  Spread 2 tbsp. Nutella® inside each bun.  Using a piping bag fitted with a star tip, pipe whipped cream over the Nutella®.  With a spatula, smooth the whipped cream so that it fills the bun completely. Drizzle remaining Nutella® over the whipped cream and sprinkle with toasted hazelnuts.
