Prep the base: Add milk and yogurt to your blender.
Starting with liquids helps everything blend smoothly.
Add flavor builders: Toss in the frozen banana, cocoa powder, caramel, nut butter, vanilla, and a pinch of salt.
Create the cookie layer: Break the graham crackers into chunks and add them to the blender. They’ll give you that Twix-like biscuit vibe.
Sweeten to taste: Add honey or maple syrup if you want a sweeter smoothie. If your caramel is sweet, you may not need much.
Blend until creamy: Start low, then increase speed for 30–45 seconds.
Add ice for a frostier texture or a splash more milk if it’s too thick.
Taste and tweak: Adjust cocoa for more chocolate, caramel for more sweetness, or a touch more salt to sharpen the flavors.
Serve it up: Pour into a chilled glass. For a dessert-style finish, top with whipped cream, a drizzle of caramel, and a sprinkle of crushed graham cracker.
