In a large mixing bowl, stir together the Greek yogurt, almond butter, and maple syrup. Once combined, fold in half of the chopped almonds (¼ cup). Set aside the bowl.
Prepare the popsicle molds by sprinkling ½ of the remaining chopped nuts into the wells.
Carefully fill the molds halfway with the yogurt mixture. Slide the popsicle sticks in, then cover them completely with the rest of the yogurt mixture. Sprinkle on the rest of the chopped almonds on top.
Pop the mold into the freezer and freeze for at least 2-4 hours.
Meanwhile, line a small cookie sheet with parchment paper and set it aside.
Once the bars are frozen, melt together the chocolate chips and coconut oil in a medium saucepan over low heat, while stirring. When the mixture is smooth, remove it from the heat.
Next, pop each bar out of the mold and coat it with the chocolate mixture using this method: One by one, lay the bar in the saucepan, then flip it to coat completely with the chocolate mixture. Lay each bar onto the prepared cookie sheet.
The chocolate should firm up right away, but you can pop the sheet back in the freezer if it needs to harden further.
