Begin by patting the cube steaks dry with paper towels.
Then season both sides with salt, pepper, garlic powder, and onion powder.
In a shallow dish, whisk together the flour, salt, pepper, garlic powder, and onion powder.
In another dish, combine buttermilk and eggs to make a wet mixture.
Dip each steak into the flour mixture, then into the buttermilk mixture, and back into the flour.
Make sure each steak is fully coated.
Heat vegetable oil in a large skillet over medium-high heat.
Once hot, carefully place the coated steaks into the oil and fry until golden brown, about 3-4 minutes per side.
Remove the steaks from the skillet and place them on a wire rack or paper towels to drain excess oil.
