Using an electric mixer on medium/medium/high, cream butter and powdered sugar in a medium-sized bowl. Add flour and salt and combine until crumbly.
With your hands, a tart tamper, or the bottom of a dry measuring cup, press the dough into the 9-inch square pan.
Bake until golden, 30-40 minutes. Because ovens vary, begin checking five minutes prior to earliest finish time. Remove and cool on a wire rack.
Meanwhile and if wanting toasted coconut - On a piece of aluminum foil spread shredded or hunks of coconut then place directly on the toaster oven rack. Set to medium toast. Coconut's quick to brown, so keep a watchful eye. Once the coconut is golden, remove from the oven. If left on the foil, the coconut will continue to cook, so transfer to a plate or bowl to cool.
Once cool, melt chocolateone of two ways:Double BoilerAdd one-inch water to double boiler or medium pot. Set over medium heat fitted with a medium bowl. Once warmed, add chopped chocolate or chips to the bowl. Melt chocolate, while stirring every so often.MicrowaveAdd chopped chocolate or chips to a microwave safe bowl. Start with 1 minute on high, then for 20 second bursts, stirring after each interval. Ready is when chocolate is almost completely melted. Stir the rest of the way until melted and a lifted spoon streams chocolate.
Pour chocolate in the middle of the baked shortbread. Hold each side of the pan and move the chocolate side to side until even across the shortbread. Place blackberries in the middle of each "imagined" square, then sprinkle with coconut and honey roasted almond slices.
Continue to cool on a wire rack. Serve room temperature, or place in refrigerator until cold. Cut into squares. Share the magic!
combinations are endless with this dessert: the original - Toblerone, cranberry, any nut. I usually use dark chocolate, hazelnuts/pecans/walnuts/almonds and dried blueberries/dates/figs/raisins and coconut. During the holidays, we've used chocolate bars with toffee, salt, etc. but drift back to plain good quality dark chocolate.
I happen to have some Trader Joe's honey roasted sliced almonds in the cabinet, so included them instead of plain roasted nuts this time. They added sweet/salty to the berries : )
squares best store airtight in the refrigerator or freezer. They seem to last forever in the freezer. We take a couple out when ready to eat and leave on the counter for 5-10 minutes.
