Gather all ingredients and equipment.
For the Dumplings
Drain and press the tofu, removing as much excess water as possible.
Heat a sauté pan on medium high heat. Add 1 1/2 tsp sesame oil to coat pan and then crumble the tofu into the pan. Try to get the pieces as small possible using a wooden spoon to smash the tofu until it resembles cottage cheese size curds.
Cook the tofu for 3-4 minutes until starting to brown. Add the garlic, 1 1/2 tsp soy sauce, 1 1/2 Tbsp rice vinegar, and maple syrup/honey.
Stir until well combined and liquid is absorbed, about 2 minutes.
Add the sesame seeds and scallions and fold together.
Remove filling from heat and allow to cool.
For the Sauce
Combine the 2 Tbsp soy sauce, 2 Tbsp rice vinegar, sambal oelek, ginger, and 1/4 tsp sesame oil in a bowl and stir to combine.
Assembling the Dumplings
There are several ways to assemble dumplings. The easiest way is to moisten the edges of the wrapper with water, scoop 1 Tbsp of filling into the center, and fold the wrapper in half, thoroughly pressing the edges together. This will work for round or square wrappers. Keep assembled dumplings under a barely damp towel to prevent drying out until all are ready to cook.
Steam dumplings for 8 minutes. Serve immediately with dipping sauce.
