Pat the chicken pieces dry with paper towels.
In a large bowl, combine the cornstarch, red pepper flakes, garlic powder, salt, and black pepper; add the chicken and toss until evenly coated.
Heat 1 tablespoon of olive oil and 2 tablespoons butter in a large heavy-duty skillet or cast-iron pan over medium-high heat until the butter melts and begins to sizzle.
Add the coated chicken to the pan in a single layer and cook 3–4 minutes per side, turning so pieces are golden and cooked through; work in batches if needed to avoid crowding.
While the chicken cooks, whisk together the minced garlic, remaining 1 tablespoon olive oil, honey, lemon juice, soy sauce, and hot sauce in a small bowl.
Pour the sauce over the cooked chicken in the pan and simmer 4–5 minutes, stirring occasionally, until the sauce thickens and coats the chicken; cook longer for a stickier glaze.
Serve the honey garlic chicken bites hot over rice, pasta, or with vegetables.
