Preheat the oven to 350°F (175°C).

In a large bowl, combine the oats and chopped pistachios.

In a separate microwave-safe bowl, heat the almond butter, honey, almond milk, vanilla extract, and salt until smooth and creamy.

Pour the wet mixture over the oat mixture and stir until well combined.

Press the mixture into a greased 9x9-inch baking dish and bake for 25-30 minutes or until the top is golden brown.

Allow the squares to cool completely before cutting into squares.

Serve and enjoy!
