1. Prepare the filling.

Break up the 3 ounces of chocolate into small pieces. Place in a microwave-safe bowl alongside the 3 tbsp of unsalted butter. Microwave in 20-second increments, stirring between each increment, until the butter has just melted and the chocolate has melted into the butter. Try not to heat more than necessary, but heat enough so that the chocolate has melted completely. You don’t want the mixture to get hot – just warm. Once all melted, set aside for a few minutes to cool.

In a food processor or blender, add the 1/2 cup shredded coconut. Pulse several times until the coconut resembles a coarse flour. Then add:

• 1/2 tbsp flour
• 1/8 cup sugar

Pulse again until well combined. Then pour in the chocolate butter combination, the 1 egg, and the 1/2 tsp vanilla. Blend until just combined. Do not overmix – you don’t want air getting into the mixture.

2. Prepare the puff pastry.

Here is the big picture: We are going to put one sheet of puff pastry on top of the other, with the filling sandwiched between the two layers. We will cut it out into a pretty circle. The layers will be stuck together with an egg wash that goes all around the edge, painted on the insides of the top and bottom layers of the pastry.

Here’s how we get there: Unfold both sheets of puff pastry, and check to make sure that they are large enough to cut a 9-inch round from. My sheets were slightly too narrow, so I sprinkled them with a little flour on both sides and rolled them out until they were about 1 inch wider.

Cut out a sheet of parchment paper large enough to fit a half sheet pan (this is the standard size sheet pan people use at home). Place the parchment on the counter. (I say place it on the counter because I find it easier to do this next part on the countertop and then transfer the parchment paper with the pastry on top to a sheet pan when you’re ready to bake.)

Choose which sheet of pastry you will use as the bottom layer, and place it onto the center of the parchment paper.

Take the 9-inch cake pan, flip it upside down onto the center of the puff pastry sheet you are using as the bottom layer. Lightly press it onto the top of the bottom puff pastry sheet – just enough to create a slight indent. Alternatively, you can trace with a table knife (very lightly, without cutting through the pastry) the outside of the cake pan. This gives you a guide for where you are going to be placing your filling and eventually cutting out your pastry. Do the same with the pastry sheet that you will be using as a top layer.

Scramble 1 egg. Then, with a pastry brush, brush the bottom layer of puff pastry just around the inside of the circle, coming in about 2 inches. On the puff pastry sheet you will use as the top layer, do the same thing. On this sheet though, spread the egg wash a little more widely because you’re going to need to flip over this sheet onto the top of the bottom layer of pastry, egg wash to egg wash. It can be hard to get perfect alignment if you only egg wash a tiny circle, and there’s no downside that I know of in painting the egg wash over too much of the top layer of puff pastry.

3. Fill the puff pastry.

Use a small spoon to scoop the filling onto the center of the circle you’ve drawn onto the bottom layer of puff pastry. Spread it out from the center until you’ve reached the egg wash. Don’t venture too far into the egg wash. Smooth the filling so that it is very flat on top, and try to minimize any bubbles in the bottom of the filling. You don’t want air trapped in the filling.

Place the orange rind onto an outer edge of the chocolate filling (you want it as close to the edge as possible, so that you are less likely to cut into it). Keep track of where you placed the rind.

Take the top sheet of puff pastry and flip it upside down onto the bottom sheet of puff pastry, so that the egg wash you painted onto the top sheet matches up with the egg wash you painted on the bottom sheet. Once you’ve flipped over the pastry, try not to move it around, or you risk the filling moving along with the top sheet. Gently smooth the top sheet of puff pastry over the filling to press out any air bubbles in the filling.

Make a tiny mark in the puff pastry where you placed the orange rind. This will serve as a reminder to you of where to be careful to cutting when you cut into the cake.

Take the 9-inch cake pan and flip it upside down again over the sheets of puff pastry. Try to make sure the filling is centered as much as possible. Then use a knife to cut through both layers of puff pastry along the outside of the cake pan. You should now have a circle. Cut a very tiny X into the center of the pastry so that the steam from the filling can vent out. The X below is too large (whoops!) — aim for about 1/2 this size.

Use your forefinger and thumb to crimp the pastry around the edge to seal in the filling, very gently. You honestly don’t really need to do this step, but it is another measure to ensure you don’t have any filling leakage.

4. Prepare to bake.

Transfer the parchment paper with the cake carefully onto the sheet pan. Brush the top of it with the remaining egg wash.

Decorate the pastry top using a paring knife to lightly cut (without piercing all the way through the pastry) little designs into the top layer over the egg wash. I started at the center, and cut little arcs radiating out to the edge.

Place the pastry into the refrigerator for about 20 minutes.

Use this time to preheat the oven to 400F.

5. Bake the pastry.

After the pastry has chilled and the oven is fully preheated, place it in the oven to bake at 400F for 30 minutes. Then reduce the temperature to 350F, and bake for 15 more minutes.

While the pastry bakes, make the glaze. Place the 1/2 cup of sugar and the 1/2 cup of water and the 1 tbsp of butter  into a small saucepan over low heat. Stir the sugar syrup until well combined, then turn off the heat.

Once the pastry is finished baking, take it out of the oven and immediately brush it all over with the sugar syrup. This will make it shiny and also help with the natural tendency of puff pastry to get soft over time.
