Breakfast for Dessert : Or is it dessert for breakfast? These outrageously indulgent milkshakes are tough to pin down. But one thing's for sure: Your guests will be amazed when you whip up a batch at your next brunch party. Start with a plain vanilla milkshake recipe, then doctor it up with different mix-ins, such as maple syrup or cereal milk. The awe factor is in the embellished glass rims, so don't skimp on the sweet decorations.
