The most tempting summertime recipes are the ones that call themselves, “No Bake” or “No Churn” or “Quick and Delicious” or “Simple Ingredients.” Well, here’s a “Four-Ingredient Peanut Butter Mousse,” from Marsha’s Baking Addiction, that gives us what it promises: four uncooked ingredients at their best.

Mix, beat, and fold. I refrigerate my mousse in serving glasses for three hours.

It’s a thick pudding: creamy sweet peanut butter. It might taste a bit decadent, but it’s so easy.
