Mix the flour, tapioca flour, baking powder, and salt together in a large bowl with a whisk.

In another bowl, beat the egg whites until soft peaks form.

Add the sugar, and beat for about another minute.

Mix egg yolks, milk, and vanilla with a whisk.

Pour the egg yolk mixture into the bowl with the flour mixture, and blend until moistened. (You should see lumps.)

Add the melted butter and stir.

Stir the beaten egg whites into the batter.

Sprinkle pecan pieces into the bottom of the hot waffle maker, greased lightly with olive oil (or other oil that you prefer).

Using a small ladle, pour the batter into the waffle maker.

Sprinkle dried cranberries on top of the batter.

Close the waffle maker, flip, and bake.

When the green light appears, flip the waffle maker back over (bake according to your waffle maker directions).

Serve with pure maple syrup, heated in the microwave (with or without extra butter).
