Method
Cook the custard base
- In a saucepan, heat the heavy cream and whole milk until steaming. While it heats, whisk the egg yolks and granulated sugar until smooth.
- Slowly whisk the hot cream mixture into the egg yolks. Return everything to the saucepan and cook until it reaches 175F, stirring constantly.
Chill and flavor
- Strain the custard into a clean container, then stir in butter extract, vanilla extract, almond extract, and salt. Continue mixing until fully combined.
- Cover and cool completely, then refrigerate for 4 hours. Chill until very cold before churning.
Churn, assemble, and freeze
- Churn the chilled custard in an ice cream maker until it thickens to soft-serve consistency. Fold in rainbow sprinkles during the last 2 minutes of churning.
- Transfer the ice cream to a container and freeze until firm. Serve with more rainbow sprinkles on top.
Notes
Pro tip: keep stirring when the custard hits 175F so it thickens evenly without scrambling. Refrigerate leftover ice cream in a sealed container for up to 1 week. Freezing is best for storage—freeze in a flat layer for quicker firming, and it keeps well for about 2 months. For a lighter option, substitute part-skim milk for some of the whole milk and use the same sugar and extracts.
