1. Craft the Crunchy Pistachio Base:
Gently pulse ½ cup of pistachios in a food processor until they become fine crumbs.In a mixing bowl, combine the almond flour, ground pistachios, granulated sweetener, and a pinch of salt.
Pour in the melted butter, egg yolk, vanilla extract, and a tiny drop of green food coloring if you like. Stir until a soft dough forms.
Press this delightful dough evenly into an 8x8 inch pan lined with parchment paper.
2. Whip Up the Creamy Pistachio Filling:
In your food processor, combine the remaining ½ cup of pistachios with the avocado oil. Pulse until it turns into a wonderfully smooth pistachio butter.Add the softened cream cheese, ¼ cup at a time, blending well after each addition until everything is super smooth.
Stir in the Greek yogurt, then blend in the powdered sweetener and salt until fully mixed.
Finally, add the egg, vanilla extract, almond extract, and another tiny drop of green food coloring if desired. Blend just until smooth – don't overmix once the egg is in!
3. Bake to Perfection:
Carefully pour the pistachio filling over your crust in the pan, spreading it evenly.Bake at 325°F (160°C) for approximately 22 minutes, or until the filling is set and lightly golden at the edges.
Let the bars cool down completely on a wire rack before moving to the next step.
4. Create the Glossy Chocolate Topping:
Gently heat the heavy cream in a small saucepan or microwave until it's hot, but not boiling.Add the sugar-free chocolate chips and stir continuously until they are completely melted and form a beautifully smooth ganache.
5. Assemble and Chill for Bliss:
Pour the warm chocolate ganache evenly over the completely cooled pistachio bars.Optional design: For a fancy touch, pipe thin green stripes (using a mixture of melted sugar-free white chocolate chips, a drop of green food coloring, and a tiny bit of heavy cream) across the chocolate, then drag a toothpick through them in the opposite direction for a marbled effect.
Sprinkle the finely chopped pistachios around the edges for a lovely finish.
Pop the pan into the refrigerator for several hours (at least 2 hours) until the chocolate topping is perfectly set.
Once chilled, slice into delightful bars using a sharp knife. Get ready to enjoy this healthy, sweet treat!
