The Birthday Cake Cookies are low-calorie, healthy, very quick and easy to make and super-delicious!
Soften the butter by leaving it sit out of the fridge for 10 minutes or in the microwave.
Whisk together the flour, salt, baking soda, and baking powder.
Put all the other ingredients in a blender and blend until smooth, or if you don't have a blender just mix everything until incorporated. Fold in the sprinkles.
Mix together the wet and the dry mixtures. Put the dough in the fridge for 15-30 minutes (or overnight) to chill.
Take 1 tbsp of dough out and roll it into a cookie. Do the same with the rest of the dough. Sprinkle some additional sprinkles on top of each cookie.
Bake the cookies at 375 F for about 15 minutes or until golden brown.
Let the cookies chill on the baking sheet before storing them and... enjoy!
