Cook Keto No-Bake Peanut Butter Bars Like This

Step 1: Prepare Your Baking Dish
Start by lining a 9×9-inch baking dish with parchment paper. This will make it easy to lift the bars out once they are set.
Step 2: Mix the Base Ingredients
In a large mixing bowl, combine 2 cups of super fine almond flour, 1 cup of unsweetened peanut butter, 1/2 cup of melted unsalted butter, 1 cup of sugar-free confectioners sweetener, and 1/2 tsp of sea salt. Mix thoroughly until you have a smooth, cohesive mixture.
Step 3: Spread the Mixture
Transfer the mixture into your prepared baking dish. Use a spatula to press it down evenly, ensuring that it reaches all corners of the dish.
Step 4: Melt the Chocolate Topping
In a double boiler or microwave-safe bowl, melt 1 cup of sugar-free chocolate chips with 2 tablespoons of butter. Stir until smooth and combined.
Step 5: Pour the Chocolate Over the Base
Once melted, pour the chocolate mixture over the pressed peanut butter base, spreading it out evenly with your spatula.
Step 6: Chill the Bars
Place the baking dish in the refrigerator for at least 2 hours or until the bars are firm and set. This chilling time is crucial to achieve the right texture.
