I want to double the following recipe. Do I need to make adjustments on the baking powder and eggs or just double everything.

2 1/4 cups all-purpose flour (do not sift the flour)
1 1/2 cups granulated sugar
3 1/2 teaspoons baking powder
1-teaspoon salt
1 1/4 cups milk
Vegetable oil
1 stick butter (not margarine), softened
1-tablespoon vanilla extract
3 large eggs

You should be able to just double everything. No adjustment needed.

I would just double it.

I always just double!

Thanks!
