Step 1 Place the softened butter and sugar in a large bowl (or the bowl of a stand mixer). With a hand mixer (or stand mixer with a paddle attachment) on medium-high speed, beat until very light and fluffy, 3-4 minutes. Add the egg and vanilla and mix well to combine. Add the flour 1 cup at a time, mixing on low to combine completely in between each addition. Scrape the bottom and sides of the bowl as needed. The primary flavors in this cookie are butter and vanilla, so you’ll want to use good quality ingredients! Butter - Use a good quality, unsalted butter. To stay as close to the original recipe as possible, I'm using Lurpak (Danish butter), which is higher in fat content, due to the additional churning. Salted butter will also work, just skip any extra salt from the ingredients. They often come in a various shapes and sizes. Piping bags with different nozzles are used to achieve some of their characteristic, twisted shapes.

I added a 1/6 cup whole milk. My hands still burned as I strained, but now the slowest, jagged little mass of dough began to poke out. I returned the dough to the bowl and added another 1/6 cup milk.

Vanilla extract – This optional ingredient really enhances the flavor. I say “optional” but I never leave it out. It is incredibly delicious- I use only the highest-quality ingredients to give the richest flavor and soft, melt-in-your-mouth texture. The iconic Danish butter cookie (or a biscuit, depending where in the world you are), in it's simplest form, is made of mix of butter, sugar and flour. They have wonderful, crisp and delicate texture, which just melts in your mouth with each bite you take. Form the dough into a long loaf which makes it easier to put in the piping bag. Step 4: Pipe the cookie shapes and bake them

Do not chill the dough alone (in a bowl or in the piping bag), as it will become too hard to handle and to pipe after. For an accurate and consistent baking experience, use a digital scaleto measure your ingredients. Since some oven models can vary by a degree or two, using a digital oven thermometeris helpful to ensure that your oven reaches and stays at the correct temperature.They are a crispy, vanilla-flavored cookie that gets their crisp texture from the amount of butter and sugar used in the recipe. They come in many shapes and sizes, depending on who controls the piping bag, and can be flavored or topped with other sweets like chocolate or coconut.
