This recipe is based on one in Thoroughly Modern Milkshakes (Norton, 2009) by Adam Ried.
- 1⁄2 cup cold milk
- 1⁄4 tsp. vanilla extract
- 1 tbsp. malted milk powder, such as Horlicks
- 4 cups caramel, caramel swirl, or dulce de leche ice cream
Put milk, vanilla, and malted milk powder into a blender and blend until combined. Add ice cream and blend, pausing once or twice to mash the mixture with a rubber spatula, until mixture is smooth and creamy, about 45 seconds. Pour milk shake into 2 chilled glasses.
