Remove the chicken breast from the refrigerator half an hour prior to cooking to allow to come to room temperature
Pat the chicken dry with paper towels.
Using a sharp knife, slice the chicken into 1-inch slices or cubes.This will help with the cooking process so that all the pieces of chicken are similar in size and cook evenly Add the all-purpose flour, baking powder, table salt, and black pepper to a shallow bowl or container. Whisk to combine the ingredients.
Place the chicken pieces in the seasoned flour, getting a good coating on the pieces, and set aside until needed.
Place a large skillet over medium-high heat.
Add three tablespoons of butter and the sesame oil to the hot pan. Swirl the butter around so it doesn't burn.
Add the pieces to the pan and cook for 4-5 minutes or until the chicken is cooked, turning the pieces to sear all sides. The chicken should have an internal temperature of 165 degrees F.
Remove the chicken from the pan and place it on a clean plate while you make the sauce. Tent the chicken with aluminum foil, to keep it warm.
Using the same pan, lower the heat to medium and add the remaining tablespoon of butter to the pan.Use a spatula to release any of the browned bits stuck to the pan. Add the chopped garlic and ginger to the pan and cook for 1-2 minutes until fragrant.
Add the soy sauce, brown sugar, rice vinegar, and honey to the pan. Stir to combine. Simmer for 2-3 minutes.
Add the bourbon to the sauce and whisk together to combine. Let the sauce continue to simmer for 2 minutes. This will burn off the alcohol.
Place the chicken back into the pan with the sticky sauce.
Fold the chicken into the bourbon sauce to give it a good coating.
Let the chicken simmer in the sauce for 2-3 minutes, turning the pieces over as it simmers.
Remove from heat and serve over fluffy white rice with your favorite vegetable.
Garnish with sesame seeds and/or sliced green onions.
