I love this. It will puff up while cooking and settle back down when cooling. I like it warm.
1&1/2 cups plain yogurt
1 tablespoon cornstarch
4 eggs
A dash of vanilla extract
2 tablespoons allulose or sweetener of choice
1 teaspoon gelatin unflavored
Optional tablespoon or two of cream cheese I think this is optional but haven’t tried it without it!
Mix thoroughly. Add to 7 inch round baking dish that has been oiled. Bake 350F for 55-60 minutes until just starting to brown lightly on the top. Cool 30 minutes at room temperature and serve.
