In a large bowl, mix together all the ingredients except for the chocolate. I used a fork and then used my hands to get the butter well combined.
1 3/4 cups (140 grams) roasted hazelnut meal, 3/4 cup + 2 tablespoons (120 gams) glutinous rice flour, 4 teaspoons Frangelico, 8 1/2 tablespoons (120 grams) unsalted butter, 1/2 cup (65 grams) coconut sugar
Preheat the oven to 350°F (176°C) and line a baking sheet with a Silpat or a piece of parchment paper.
Roll the dough into 1/2" balls and place 1" apart on the baking sheet.
Bake the cookies for 7 minutes. They should be set but not have turned brown yet.
Remove from the oven and let cool completely.
Melt the chocolate in a microwave safe bowl at 50% power in 30 second increments, stirring after each increment.
1/4 cup (45 grams) semi-sweet chocolate chips
When the cookies are completely cool, dollop a tiny bit of chocolate on the center of a cookie and sandwich it together with another cookie. Repeat with the rest of the cookies.
Place the assembled cookies back on the Silpat or parchment paper you used for baking and let the chocolate harden. If you're in a hurry, place them in the fridge to harden quicker.
Cover the cookies and let sit at room temperature for up to 5 days.
