In a mixer, beat eggs on high for approximately 5 minutes. Once the time is up, your eggs should be light and foamy.
Next, grab a large bowl and add baking powder, flour, and confectioner’s sugar. On a low speed, gently add in your extracts and shortening until it’s turned into a fine powder/crumb-like consistency. Add in eggs.
Roll your dough into 1” sized balls and place them about 2” apart on a baking sheet. Make sure the baking sheet isn’t greased.
Bake at 350 degrees for approximately 13 minutes. Don’t wait until the tops of the cookies are brown, as this could result in burning.
While these are cooking in the oven, go ahead and mix the sugar, milk, and other extracts until smooth. As soon as the cookies are done baking, quickly dip them into the glaze.
Once glazed, place on a wire rack and add sprinkles.
Let them dry for 24 hours before adding them to a Tupperware dish.
