"My husband and son love eggnog. I wanted to make it sugar-free. A seasonal favorite with an autumn flair. Microwaveable. (Unfortunately, not low-fat ... yet.) Enjoy hot right away or cold the next day. I like to add it to my coffee."
Pour half-and-half into a microwave-safe measuring cup. Add cinnamon, clove, and nutmeg. Heat in the microwave for 1 minute. Stir. Microwave for 1 minute more.
Mix eggs yolks in a bowl using a fork; add sucralose sweetener. Add 1 teaspoon of the half-and-half mixture to the egg yolk mixture. Repeat until all half-and-half has been incorporated. Remove clove and discard. Add pumpkin puree and pour eggnog back into measuring cup.
Heat eggnog in the microwave for 30 seconds on low. Stir. Repeat heating and stirring 3 more times until slightly thickened.
