Heat oil in a deep-fryer or large saucepan over medium heat.
Mix flour, garlic powder, salt, and black pepper together in a shallow bowl. Beat eggs in a separate bowl.
Dip jalapeno slices in beaten eggs, then coat generously with flour mixture.
Fry coated jalapeno slices in the hot oil, working in batches, until peppers are golden brown, 2 to 3 minutes per side.
To cut out spiciness, soak jalapeno pieces in a mixture of water and milk (just a splash) and put in freezer for about 45 minutes.
