Gâteau au yaourt / Yogurt cake might be the most easy cake in French opinion. And the funny thing is that in France most people absolutely like to weight ingredients and don’t really know how to do with cups as in the United-States, whereas this basic of French home baking is the no-measuring cake. Start by pouring a yogurt in a bowl then use the yogurt container (called pot in the ingredients, hope this is the correct word) as a measuring cup for other ingredients (sugar, flour and oil) It’s the first thing French kids start to bake on their own and then bake again and again. Always super moist and very tasty. My version when I was a child in the Alps was with pears and chocolate, see my childhood recipe here and this other yogurt cake with oranges.
Be that as it may from a simple recipe you can add all kind of ingredient to flavor or fruit. Today my proposal is with a mix of redcurrant and blackcurrant (those were picked in my garden just next to Paris) and an apple.
