Spread wheat germ over a baking sheet.
Bake in the preheated oven until toasted, about 5 minutes. Cool slightly, then transfer wheat germ to a large bowl.
Stir flour, baking soda, and salt into wheat germ. Beat buttermilk, eggs, and oil in another bowl until smooth; pour egg mixture into flour mixture and stir until batter is just blended.
