- Take some of the brown dough and make it into a rectangular prism so that the short sides measure 1 1/4 x 3/4" and place it so the longer edge (1 1/4") is parallel with your table.
- Next take a red piece of dough and make a rectangular prism with 3/4 x 1/2" short sides. Center this red rectangular strip on top of your first brown one with the longer edge (3/4") touching the brown dough.
- Then make two narrow rectangular prisms with the brown dough with the short sides measuring 3/4 x 1/4". Place them on both sides of the red rectangular piece of dough with the shorter edge (1/4") touching the brown base.
- Finally, make another brown rectangular prism with the short side measuring 3/4 x 1/4". Place that prism on top of the red prism and between the other two narrow brown prisms.
- Now smooth away the lines between the dough pieces and round the corners of your large rectangular prism. I find it easier to repeat this whole process multiple times with all of the dough to ensure that the shape of the mouth doesn't get distorted by working with too much dough at once.
- Once finished, wrap the shaped dough in plastic wrap and refrigerate till firm, around 30 minutes. When ready to bake, preheat the oven to 350°F. Take the dough out from the fridge and slice it into 1/8-inch pieces, placing them onto parchment lined baking sheets. Bake them for 12 minutes.
- Let them cool on the sheets for 5 minutes, then transfer them to a cooling rack. Once the cookies are totally cool, they can be filled.
- First pair up all your cookies by size. Only one cookie in each pair will need to be decorated (since the other cookie will be the bottom of the sandwich). Place the white chocolate ganache in a piping bag.
- Take one cookie from a pair and pipe a bit of filling in the center. Place the other cookie on top and carefully press the cookies together to spread out the filling to the edges. Repeat with the rest of the cookies.
