Pouding à la rhubarbe (or Rhubarb Pudding Cakes, which just does not roll off the tongue as well) is amazing! Pouding recipes are big in our house - making them makes me want to move back to Québec. They are the ultimate comfort desserts. The individual serving sizes of this recipe (they are generous portions) are perfect for serving in ramekins. I brought my individual poudings to a dinner party and they were very popular. Ricardo Cuisine has the recipe here.
Note: These definitely bubble over. The recipe suggests putting the ramekins on a cookie sheet - I would also recommend lining the cookie sheet entirely with parchment paper and then placing the ramkeins on top. Easier clean up. Bon appétit!
