Preheat your waffle iron according to the manufacturer’s instructions and give it a good coat of cooking spray.
In a big bowl, whisk together the flour, baking powder, salt, black pepper, and sugar so everything’s nicely mixed.
In another bowl, beat the eggs, then pour in milk, melted butter, and canola oil. Whisk until it’s smooth.
Pour the wet ingredients into the dry and stir until just combined—don’t worry about a few lumps, really, it’s fine.
Gently fold in the shredded cheddar with a spatula so it’s spread throughout the batter.
Scoop the batter onto the hot waffle iron (amount depends on your machine), close the lid, and cook until the waffles look deep golden and crisp.
Take the waffles out carefully and serve while they’re hot. They’re fantastic with sausage, sautéed apples, and maybe a little maple syrup if you’re into that.
