Ingredients

• 1 1/4 cups creamy unsweetened almond butter
• 1/3 cup coconut oil, melted
• 1 1/2 cups vanilla whey protein isolate (about 4 scoops)
• 3/4 cup blanched almond flour
• 1/4 cup powdered erythritol or monk fruit sweetener
• 2 tbsp ground golden flaxseed
• 1 tsp vanilla extract
• 1/4 tsp fine sea salt
• 3 to 4 tbsp unsweetened almond milk, as needed
• 3/4 cup sugar-free dark chocolate chips
• 1 tsp coconut oil (for the chocolate topping)

Instructions

1. 1

   Line an 8x8-inch baking pan with parchment paper, leaving an overhang on two sides so you can lift the bars out later.

2. 2

   In a large bowl, stir together the almond butter and melted coconut oil until smooth. Add the vanilla and salt and mix well.

3. 3

   Add the whey protein isolate, almond flour, powdered sweetener, and ground flaxseed. Stir until a thick, stiff dough forms. If it feels dry or crumbly, add almond milk one tablespoon at a time until the dough holds together when pressed.

4. 4

   Transfer the dough to the prepared pan and press it down firmly and evenly with a spatula or damp hands, packing it into a tight, flat layer.

5. 5

   Melt the chocolate chips with 1 tsp coconut oil in 20-second microwave bursts, stirring between each, until smooth. Pour over the dough and spread into an even layer.

6. 6

   Refrigerate for at least 1 hour, until the chocolate is set and the bars are firm. Lift out using the parchment, then slice into 12 bars.

Tips & notes

• Store the bars in an airtight container in the fridge for up to 1 week, or freeze for up to 3 months. Separate layers with parchment so they don't stick.
• No vanilla whey? Use an unflavored or chocolate whey isolate and adjust sweetener to taste. Casein or egg-white protein also work, but you may need an extra splash of almond milk since they absorb more liquid.
• For a nut-free version, swap almond butter for sunflower seed butter and replace the almond flour with an equal amount of extra protein powder plus 2 tbsp coconut flour.
