Simple Chocolate Ice Cream

Step 1
Fill sink with several inches of ice water.

Step 2
Beat eggs and cocoa powder in a bowl until well-blended and smooth.

Step 3
Heat milk, evaporated milk, sugar, and cocoa powder mixture in a heavy-bottomed saucepan over medium-low heat, whisking constantly, until custard comes to 180 degrees F (82 degrees C), about 10 minutes. The custard should be thick enough to coat the back of a spoon.

Step 4
Remove saucepan from heat and immediately transfer to sink to halt cooking. Continue to stir custard until cooled; stir in vanilla extract.

Step 5
Pour custard into an ice cream maker once it reaches 40 degrees F (4 degrees C). Freeze according to manufacturer's directions until softly frozen. Transfer ice cream to a lidded container; cover surface with plastic wrap and seal. For best results, ice cream should ripen in the freezer at least 2 hours to overnight.
