Use a handheld or stand mixer fitted with the paddle attachment to beat the vegan butter or coconut oil for 1 minute. It should become smooth and creamy. Add sugar and beat further on high speed for 2-3 minutes until fluffy and light.

Add in the almond milk, cornstarch, baking powder, salt and vanilla extract. Beat on high until it is all fully combined, about 1 minute.

Add 1 cup of the flour to the wet mixture. Mix on low speed, until just combined. Scrape the sides of the bowl. Add the rest of the cup of the flour and continue to mix on low until just combined. Do NOT over mix.

Scoop all of the dough out of the bowl on a clean working surface. Gently roll the dough to make a smooth round. Put it in an airtight container and chill in the refrigerator for at least 1 hour or overnight.

Once the dough has been chilled, take it out on the counter for 10 minutes. Meanwhile, preheat the oven to 350° Fahrenheit.

Line two baking sheets with parchment paper. Using a cookie scoop, drop the dough on the baking sheet. Keep them 2" apart.

( If you want to make cutout cookies, dust the working surface with some flour, roll the dough with a rolling pin about ½ inch thick and press the cookie cutter. Place them on the prepared baking sheets. You can re-roll the edges of the dough until it is all used.)

Bake for 8-10 minutes, in the middle rack of the oven. The cookies expand and look lightly colored on top and around the edges.

Remove from the oven and let them cool for 10 minutes on the counter. Then transfer to a wire rack to let cool completely before icing.

Note : When you remove the cookie baking sheet from the oven, cookies will appear underdone. They will firm up considerably as they cool down. So do NOT over bake them.

Whisk all icing ingredients in a bowl. Pick up the cookie and dip in the icing and put it back on a wire rack to cool down. Alternatively, use brushes, spoons or a piping bag to put icing on each cookie.

Sprinklers can be put on when icing is wet. The icing will take roughly 2-3 hours to harden completely.

You can air fry these cookies. Make and arrange the cookies on the air fryer basket instead of baking sheet as described above.

Air Fry at 375 degree Fahrenheit for 7 minutes. Check the doneness and continue for 2 additional minutes if needed.
