This shake disappeared in minutes at our spring gathering! The earthy matcha flavor combines beautifully with sweet Oreo crumbles, creating a perfectly balanced dessert drink. Thick, creamy, topped with whipped cream - it's like drinking a green tea ice cream dream.
Place vanilla ice cream, whole milk, matcha powder, and granulated sugar into a high-powered blender.
Blend on medium-high for 30–45 seconds, scraping down sides as needed, until the matcha is fully dissolved and the shake is thick and creamy.
Add 4 Oreo cookies. Pulse blend a few times (5–10 seconds) to leave some chunky cookie bits for that signature Jack in the Box Oreo crunch.
Pour the shake evenly into two chilled glasses. Top generously with whipped cream.
Crumble the remaining 2 Oreos over the whipped cream for classic texture and serve immediately. This assembly mimics Jack in the Box's thick, spoonable shake presentation.
