Gather all ingredients and prep your cooking gear. Get your pressure cooker ready, and make sure the sealing ring is clean and well-fitted so no steam escapes during cooking.
Cream together the cold cubed butter with both sugars until you get a light and fluffy mix. Don't rush this part since it builds your cookie's structure.
Add the eggs, red food coloring, and vanilla extract to the butter mix. Mix everything well until you get a nice red velvet color with creamy texture.
In a separate bowl, whisk the flour, cocoa powder, baking powder, baking soda, and salt. This pre-mix helps your dry ingredients blend even in the wet dough.
Gradually add the dry mix into the wet batter. Stir gently just until you don't see flour anymore. Overmixing can toughen the dough, so keep it easy.
Fold in those white chocolate chips slowly so they spread evenly through the batter without breaking up much.
Scoop big dollops of dough on a piece of parchment paper inside the pressure cooker basket.
Add about one cup of water into the cooker base, cover carefully, and seal the lid.
Pressure cook at high pressure for about 10 minutes, then let the pressure release naturally to get the best texture.
Notes
To store, use an airtight container with a slice of bread to keep cookies soft, or freeze in zip-top bags and warm gently when ready to eat again.
