We made speculaas cookies last night. I’d take pictures, but they didn’t turn out well because I made a mistake. Remarkably, I’ve never made this mistake before, and I’ll never make it again.
I used baking soda instead of baking powder.
Here is a great article about why these two white powders should not be switched. The quote that applies to my mistake is this:
“Since baking powder contains an acid already, it doesn’t need another acidic ingredient in order get a reaction and you don’t have to worry quite so much about a metallic aftertaste.”

My cookies have a pronounced metallic aftertaste because of the baking soda. They aren’t inedible, but I can’t give them as gifts. We’ll make another in a week or so, and I’ll be sure to do it right.
I hope your Christmas baking is mistake-free. Doublecheck the recipe and the container when it comes to baking soda and baking powder.
