Then join the wet and the dry ingredients and mix well.
Now take a spoon and put the dough in a forcing bag with a large opening.
Put the dough with the forcing bag onto the baking paper previously laid on the baking pan and create 8 circles, 0.5 cm high.
Now bake for not more than 10 to 12 minutes
Take them out and let them cool out before any frosting is added on their backside.
As a frosting you can put a lot of different types. Honey is working as well as jam and marmalade. I liked my jam in the middle of them. But I tried them also with a creamy cheese-lemon one (nut cream cheese, lemon zest, a little honey). Really very fresh! Especially great in summer.
Very nice to give the whoopies a color, I didn't have any unfortunately when doing them. Try to put two different colors and the frosting as third color. For example for flag-looking whoopies.
