No-Bake Brownies Recipe

Line an 8-inch square baking pan with parchment paper, leaving an overhang on the edges. Set aside.

Place ¼ cup walnuts in a food processor and pulse until coarsely chopped. Transfer to a bowl and set aside.

Place remaining walnuts, almonds, and salt in the food processor; process until fine. (Don't process too long or else the mixture will turn into nut butter.) Transfer to another bowl.

Place dates and vanilla in the food processor; process until finely chopped and sticky. Add water by the tablespoon (about 4 to 5 tablespoons or as needed), whizzing until a ball forms.

Add cocoa powder and process until combined. Occasionally stop whizzing to scrape the sides of the bowl with a spatula or spoon.

Add walnut-almond mixture; pulse until combined. If the mixture seems thick, use a spoon to mix it through.

Transfer mixture to prepared pan and press down with a silicone spatula or your hands. Sprinkle with chopped walnuts.

Cover pan with plastic wrap and freeze for 30 minutes or refrigerate for at least 1 hour before slicing with a sharp knife. Serve frozen or chilled. (Store sliced brownies in the freezer for up to 3 months, with layers of plastic wrap or wax paper in between.)
