Whisk together the flour, garlic powder, salt and pepper in a shallow dish.
Dredge both sides of the chicken in the flour mixture.
Put a pan over medium heat and spray with olive oil spray. Add the chicken and cook 4 minutes.
Spray the other side of the chicken with olive oil spray and flip. Cook an additional 3-4 minutes or until the chicken is cooked through.
Remove the chicken from the pan and cover with foil.
Add the butter to the pan. Add the minced garlic once the butter has melted. Cook for 30 seconds making sure not to let the garlic get brown.
Add the wine, lemon juice, half and half and capers. Let simmer for 3 minutes then add the chicken back into the pan. Check to see if it needs any additional salt and pepper.
