You can use a 9, 10 or 12-cup bundt pan to bake the flan using the measurements above. To make it in the pressure cooker, you can use a 5 or 6-cup bundt pan for a 6 quart pressure cooker, and make sure to halve the amount of ingredients, easy peasy math!
Coat a bundt pan with shortening. Sprinkle the pan with sugar. Make sure it’s all coated with shortening and sprinkled with sugar evenly.
Pre-heat oven to 350F. Place bundt pan in a larger pan that has about 2 inches of water in, to create a water bath.
I used a 6-quart pressure cooker to cook this flan in a 5-cup bundt pan, and I halved the ingredients amounts listed above.
Wiggle the bundt pan around and if the flan is loose in there, you can flip it onto a plate.
