This is a recipe video for a rich Basque cheesecake that can be made with just four ingredients: cream cheese, sugar, eggs, and yogurt, without using flour or heavy cream. Cream the cream cheese until smooth, then add the sugar, eggs, and yogurt and mix well. Pour the mixture into a baking pan lined with parchment paper and bake in a toaster oven for 15 minutes, then cover with aluminum foil and bake for another 15 minutes. The cheesecake is done when the center is slightly wobbly. Let it cool down, then refrigerate for at least 4 hours to set, and you will have a Basque cheesecake with a melt-in-your-mouth smooth texture.
