In a measuring cup or large bowl, mix together your honey, soy sauce, sriracha, and chicken stock. Set aside.
On sauté mode (medium or high is fine), add some olive oil to your Instant Pot and add your chicken cubes into the pot.
Add salt & pepper to taste to your chicken and let the chicken brown slightly. This helps to seal in the moisture. If you are in a hurry, you can skip this step.
Add in crush garlic cloves then add in the spicy honey garlic mixture. Put the lid on your Instant Pot, set the valve to sealing, and then pressure cook for 6 minutes.
Once done, quick release your Instant Pot, remove the chicken, and add a cornstarch slurry (1:1 cornstarch to liquid ratio), and set it to sauté (low) to thicken up your sauce. Return the chicken to the pot once thicken to coat the meat.
When ready to serve, sprinkle on some chili pepper flakes to add a little bit more spice to the dish. Top with green onions as garnish if you wish.
