Pour water into the Instant Pot.
Add sweet potatoes to a steamer basket, and place the basket in the Instant Pot. Alternatively, place the sweet potato quarters on a trivet.
Lock the lid, turn the knob to Sealing, and cook on Manual High pressure for 35 minutes*.
Preheat the oven to 375.
Prepare streusel in the last couple minutes of pressure cooking by combining all ingredients in a bowl and mixing to combine.
Turn the knob on the Instant Pot lid to Venting and perform a quick release.
Lift the basket out of the instant Pot and place on a plate or towel. Drain the dirty water out of the Instant Pot liner and rinse or wash. Return the liner to the Instant Pot base and add the butter, sugar, salt, cinnamon, and vanilla.
Using a paring knife, carefully peel the sweet potatoes and return back to the Instant Pot on top of the butter. The residual heat will melt the butter. Using a hand mixer or potato masher, blend sweet potatoes until fluffy and creamy. Add the beaten eggs while mixing to combine.
Spray a 9×13 pan with nonstick spray, and spread the mixture evenly.
Add a generous layer of the streusel topping and bake for 30-35 minutes until the streusel is firm and golden.
Let cool for 10 minutes to set, and enjoy.

Sweet potatoes vary tremendously in size. I use 4-6 sweet potatoes for this dish and measure about 8 cups of total cooked sweet potato before adding any additional ingredients.
*Depending on how large your sweet potato quarters are, they may cook anywhere from 20-40 minutes in the Instant Pot. Try to keep your sweet potato chunks as uniform as possible, and a maximum of 1½ inches thick.
The sweet potato mixture can be made in advance up to a day or two. When you’re ready to cook, take it out of the refrigerator and let it come to room temperature for about an hour. Top with the streusel, and bake for 40-50 minutes or until heated through and the streusel is golden. If it starts getting too browned, place a piece of foil on top while it finishes cooking through.

Make sure you buy orange sweet potatoes, not the tan colored yams that live right by them in the grocery store. Sometimes I scratch a tiny bit of the skin off to double check.
If you don’t want to use your hand mixer in the Instant Pot, you can do everything in a large bowl after pressure cooking the sweet potatoes.
This recipe can be halved and baked in an 8x8 or 9x9 dish.
