In a medium bowl, beat whipping cream, sugar, and ½ teaspoon vanilla until soft peaks form. Set aside.
In a shallow bowl, whisk eggs, half-and-half, brown sugar, 1 teaspoon vanilla, and cinnamon. Dip each croissant half into egg mixture, coating both sides (letting each side soak about 10 seconds).
In a skillet, melt 1 Tablespoon butter over medium heat. Add half of the croissant slices and cook for 2-3 minutes per side, or until golden brown. Repeat with remaining butter and croissant slices.
Fill each croissant with berries and whipped cream. Sift powdered sugar on each one and drizzle with honey or maple syrup, if desired. ENJOY!!
