Add about ¼ the dry ingredients to the egg whites. Fold with spatula till combined.

Then add the rest of the dry ingredients and gently macaronage (fold) till “lava” texture is reached. The batter should make ribbons that don’t break when you lift the spatula. Try making a figure 8.

Line 2 cookie sheets with parchment, using a tiny dab of batter on each corner as glue.

Add batter to a piping bag using a plain round tip.

Pipe about 1 ½” circles, holding the bag perpendicular to the cookie sheet. To break off batter, make a little swirl motion on top.

Bang sheet on counter to get rid of bubbles and to help tops get smooth.

Preheat the oven to 300 degrees F.

Bake for 10 - 15 minutes. You should be able to see the “feet”.

Let cool completely before piping in the filling. Match up with the same sized tops and bottoms.
