The recipe

Exact quantities, then the method.

This biscuit milkshake is a thick, diner-style shake built on Tetley Digestive Biscuits tea, a Black Tea brewed strong then chilled so it tastes properly of malty biscuit without watering the shake down. Real digestives go into the blender too, for that crushed-biscuit texture.

It is tea and biscuits, in a milkshake. Five minutes, no cooking, and it makes two tall glasses.

⏱ 10 min 🍽 Makes 2 📊 Easy 📚 Biscuit Recipes

You'll need

  • 3 Tetley Digestive Biscuits tea bags
  • 100ml just boiled water, for a strong concentrate
  • 4 large scoops vanilla ice cream
  • 150ml cold milk
  • 4 digestive biscuits, plus 1 to crumble on top
  • 1 tablespoon caramel or honey, optional
  • Squirty or whipped cream, to finish

Method

  1. Steep 3 tea bags in just 100ml just boiled water for 5 minutes for a strong concentrate, then chill it in the freezer for 10 minutes so it does not melt the ice cream.
  2. Put the ice cream, cold milk, 4 digestive biscuits, the chilled tea concentrate and the caramel into a blender.
  3. Blend in short bursts to a thick, spoonable shake. Add a splash more milk only if it will not move.
  4. Pour into two tall, chilled glasses.
  5. Top with whipped cream and the crumbled digestive. Serve straight away with a fat straw and a spoon.
What you'll end up with: A thick, malty, diner-style milkshake that really tastes of biscuits and tea, with a crushed-digestive crunch on top. Rich and ready in minutes.
