Ingredient Notes:
Store tightly covered — first with plastic wrap, then a layer of aluminum foil — toward the back of the freezer, for up to 2 weeks.
- Heavy cream — use it cold, straight from the fridge. Whipped to stiff peaks, it's what gives this ice cream its texture without a machine.
- Sweetened condensed milk — sweetens the base and keeps it scoopable straight from the freezer instead of freezing rock-hard.
- Bananas — use ripe bananas for the best banana flavor.
- Digestive biscuits — break into a mix of chunks and crumbs, not all one size. Graham crackers work as a substitute.
- Toffee/caramel sauce — store-bought keeps this quick, but your own stovetop toffee (from the Banoffee Pie/Cups recipes) or a salted caramel sauce work too.
- Cold cream (and a chilled bowl, if needed) whips faster and holds more volume — key to a soft, scoopable texture.
- Fold, don't stir, once you add the condensed milk and banana — stirring deflates the whipped cream and gives you a denser, icier result.
- Don't over-swirl the toffee — distinct layers give you a better mouthful than mixing it in completely.
