Called dream cookies because of their airy texture, these Swedish holiday treats are meant to dissolve in your mouth when you eat them.
- 1 2⁄3 cups flour
- 1 tsp. baking soda
- 8 tbsp. unsalted butter, softened
- 1 1⁄4 cups sugar
- 1 tbsp. vanilla sugar
- 1⁄3 cup corn oil
Heat oven to 300°. In a small bowl, whisk together flour and baking soda; set aside. In a large bowl and using a handheld mixer on medium speed, beat butter and sugars until pale and fluffy, 1–2 minutes. Add oil and mix until smooth. Add dry ingredients and stir until just combined.
Using a tablespoon-size measuring spoon, divide dough into about 40 portions. Using your hands, shape dough portions into balls. Place dough balls 2" apart on baking sheets lined with parchment paper. Bake 1 sheet at a time until cookies crack on top and are just set, 25–30 minutes. Transfer to a wire rack and let cool before serving.
