Gather the ingredients.
Lightly grease the silicone egg molds with non-stick cooking spray.
Mix the crushed graham crackers and butter for the crust.
Spread the graham crust mixture evenly in the bottom of each cup. Press the crust gently into each cup.
Beat the cream cheese and sugar on medium-low until smooth.
Stir in the flour, sour cream, and vanilla. Add one egg at a time until almost incorporated. Do not overmix.
Pour the cheesecake batter into each cup. If there are air bubbles, gently tap the mold on the counter.
Place a paper towel over the filled silicone mold. Cover with foil. Repeat with the other silicone mold.
Pour a cup of water into the Instant Pot and put the trivet in the bottom. Lower the molds into the Instant Pot, ensuring they're slightly offset when stacked.
Lock the lid and select High Pressure. Cook for 5 minutes.
Turn your Instant Pot off and perform a 10-minute natural pressure release.
Finish with a quick pressure release. Once the valve drops, remove the lid from your Instant Pot.
Take out the molds and carefully remove their covers.
Bring the cheesecake bites to room temperature.
Cover the cheesecake bites with plastic wrap. Allow them to sit in the fridge overnight or for at least 4 hours to set.
Dip an offset spatula in hot water and wipe it dry. Use it around the rim of each cup to loosen the cheesecake bites from the mold.
Turn them out onto a plate and top with whipped cream and berries. Enjoy your Instant Pot cheesecake bites!
