Slice the chicken breasts in half lengthwise to create four thinner cutlets. Season each piece with garlic powder, salt, and pepper before lightly coating them in flour.
Heat olive oil and one tablespoon of butter in a skillet over medium-high heat. When the skillet is hot, sear the chicken cutlets for 4–5 minutes on each side until they are golden brown. Adjust the heat if oil splatters excessively. Remove the browned chicken from the pan and set aside.
Remove the skillet from the heat. Add the remaining butter, chicken broth, Dijon mustard, and honey to the pan, stirring until combined.
Return the pan to medium heat, ensuring the mustard fully dissolves without letting the liquid reduce entirely. Add the cream and stir until the mixture starts to bubble gently.
Return the chicken to the skillet, cooking for another 5 minutes or until the chicken is fully cooked and the sauce has thickened to your preference.
