Rolled cookies & cream ice cream

Cream-filled cocoa biscuits chopped into a vanilla base — a flavour children especially love.

Oreo-style biscuits are chopped finely on the pan and turn the mix greyish brown with dark specks. They are dry and sweet, so they don’t thin the layer and the rolls curl beautifully. One whole biscuit on top and you’re done.

Equipment

Ingredients

  • 120 g whipping cream 33 %
  • 190 g whole milk 3.5 %
  • 100 g sweetened condensed milk (sweetened, from a tube or tin)
  • 3 g vanilla extract (1 teaspoon)
  • 45 g cream-filled chocolate sandwich biscuits (Oreo-style) (about 4–5 biscuits)
  • 30 g cream-filled chocolate sandwich biscuits (Oreo-style) (for topping or folding in at the end, 3 whole biscuits)

Making the mix

  1. Whisk the cream, milk and condensed milk (plus the sugar or vanilla, if the recipe has them) until smooth — don’t whip it into a foam; the mix should stay liquid.
  2. Break the biscuits for the mix into quarters.
  3. Put the mix in the freezer for 30 minutes or in the fridge for at least an hour — the colder it is, the faster it sets on the pan.

Method — Ice pan for rolled ice cream

  1. Take the ice pan or tray out of the freezer only just before you start and set it on a dry tea towel so it doesn’t slide. Have two flat metal scrapers and all the add-ins ready.
  2. Pour about a third of the mix (about 130–150 ml) onto the pan. Add 2 broken biscuits and chop it right into the mix with the edges of the scrapers until it starts to thicken.
  3. Quickly spread the mix into a thin, even layer 2–3 mm thick, in a rectangle about as wide as a scraper.
  4. Let the layer set — 2–5 minutes on a home ice pan. It is ready when the surface stops being glossy and the layer is firm but still flexible.
  5. Slide a scraper under the edge of the layer at an angle of about 45° and push it firmly away from you — the layer curls into a roll. Transfer the rolls straight into a glass or bowl.
  6. Return the pan to the freezer for at least 20 minutes until it is cold again, then make the next portion. Keep the mix in the fridge in the meantime.

Professional pans are cooled by a compressor to about −30 °C and a portion is done in 2 minutes. A home ice pan with a cooling gel or a tray from the freezer only reaches about −18 to −20 °C and warms up quickly — hence a small portion, a thin layer and fast work. Freeze the pan according to the manufacturer’s instructions; a tray for at least 12–24 hours in the coldest part of the freezer. On a tray the layer often won’t set on the worktop: in that case spread it out, put the tray back in the freezer for 10–20 minutes and only then roll. Don’t scratch a non-stick surface with a metal scraper.

Serving and storage

Stand the rolls in a glass, push a whole biscuit into the middle and drizzle with chocolate sauce if you like. Serve straight away.

Not for storing — thin rolls stick together, harden and frost over in the freezer. Eat them straight away. Unused liquid mix keeps, covered, in the fridge until the next day.

Tips

  • Chop the biscuits as small as you can. Big pieces tear the layer and the roll falls apart.
  • The biscuits contain gluten and usually soya too — on a gluten-free diet, use gluten-free cocoa biscuits.
  • The most common mistake is a thick layer or a pan that isn’t cold enough: the mix then won’t set, and when you start rolling it tears. Better a smaller portion and a thinner layer.
  • If the layer cracks, it is too hard — let it soften for 30 seconds. If it squashes and won’t curl, it isn’t firm enough yet.
