Daring Bakers- Tuiles

This month's challenge is brought to us by Karen of Bake My Day and Zorra of 1x umruehren bitte aka Kochtopf. They chose Tuiles from The Chocolate Book by Angélique Schmeink and Nougatine and Chocolate Tuiles from Michel Roux.
I made the regular tuiles paired with spumoni ice cream. The tuiles spread a LOT when I baked them so the three I had on my baking sheet turned into one. These were a lot of fun, if not very noteworthy in the taste category.Following is a recipe taken from a book called “The Chocolate Book”, written by female Dutch Master chef Angélique Schmeinck.
Recipe:
Yields: 20 small butterflies/6 large (butterflies are just an example)
Preparation time batter 10 minutes, waiting time 30 minutes, baking time: 5-10 minutes per batch

¼ cup softened butter (not melted but soft)
½ cup sifted confectioner’s sugar
1 sachet vanilla sugar (7 grams or substitute with a dash of vanilla extract)
2 large egg whites (slightly whisked with a fork)
1/2 cup sifted all purpose flour
1 table spoon cocoa powder/or food coloring of choice
Butter/spray to grease baking sheet

Oven: 350F

Using a hand whisk or a stand mixer fitted with the paddle (low speed) and cream butter, sugar and vanilla to a paste. Keep stirring while you gradually add the egg whites. Continue to add the flour in small batches and stir to achieve a homogeneous and smooth batter/paste. Be careful to not overmix.
Cover the bowl with plastic wrap and chill in the fridge for at least 30 minutes to firm up. (This batter will keep in the fridge for up to a week, take it out 30 minutes before you plan to use it).
Line a baking sheet with parchment paper or grease with either butter/spray and chill in the fridge for at least 15 minutes. This will help spread the batter more easily if using a stencil/cardboard template such as the butterfly. Press the stencil on the bakingsheet and use an off sided spatula to spread batter. Leave some room in between your shapes. Mix a small part of the batter with the cocoa and a few drops of warm water until evenly colored. Use this colored batter in a paper piping bag and proceed to pipe decorations on the wings and body of the butterfly.
Bake butterflies in a preheated oven (350F) for about 5-10 minutes or until the edges turn golden brown. Immediately release from bakingsheet and proceed to shape/bend the cookies in the desired shape. These cookies have to be shaped when still warm, you might want to bake a small amount at a time or maybe put them in the oven to warm them up again.
If you don’t want to do stencil shapes, you might want to transfer the batter into a piping bag fitted with a small plain tip. Pipe the desired shapes and bake. Shape immediately after baking using for instance a rolling pin, a broom handle, cups, cones….
