To make these sushi cups, start by preheating your oven to 350°F and lightly greasing a muffin tin.
Next, prepare the filling. In a medium bowl, combine the chopped imitation crab, chopped shrimp, softened cream cheese, Kewpie mayo, sriracha, and soy sauce. Stir everything together until the mixture is smooth and well combined, then set it aside.
Once the filling is ready, crumble two sheets of seaweed and press into the bottom of each cavity of the muffin tin.
After that, scoop two to three tablespoons of rice into each cavity. Use the back of a spoon to press the rice down tightly.
Then, scoop the crab and shrimp mixture on top of the rice into each cavity, dividing it equally.
Place the muffin tin in the oven and bake for 16-17 minutes. After baking, broil on high for 2-3 minutes, or until the tops are golden and slightly crispy.
Remove the muffin tin from the oven and allow the sushi cups to cool before gently removing them.
Finally, garnish the sushi cups with spicy mayo, avocado, chopped chives, and a sprinkle of furikake before serving. Enjoy!
