  • 50g (scant ½ cup) honey or maple syrup
  • 1 ¼ tsp vanilla extract
  • 50g (⅔ cup) vanilla or neutral protein powder
  • 75g (scant ⅔ cup) almond flour or oat flour
  • ⅔ tsp baking soda
  • 40g (¼ cup) dark chocolate chips

Directions:

Preheat & Prep the Pan
  1. Preheat your oven to 350°F (175°C) and line a 9×9-inch (23×23 cm) baking pan with parchment paper.
Make the Brownie Batter
  1. In a bowl, mix together applesauce, coconut oil, honey (or maple syrup), egg, and vanilla until smooth.
  2. Stir in protein powder, cocoa powder, almond flour, baking powder, and salt until just combined.
  3. Fold in the chocolate chips and pour the batter into the prepared baking pan.
Make the Cookie Dough
  1. In a separate bowl, whisk the egg, almond butter, honey (or maple syrup), and vanilla together.
  2. Stir in protein powder, almond flour, and baking soda until a soft dough forms.
  3. Gently fold in the chocolate chips.
Assemble the Brookies
  1. Drop spoonfuls of cookie dough over the brownie batter.
  2. Use a knife or spatula to lightly swirl the layers together for a marbled effect.
Bake & Cool
  • Bake for 20–24 minutes until the top is set but the center is slightly soft (don’t overbake!).
  • Let them cool in the pan for at least 15 minutes before slicing.
  • For an extra fudgy texture, refrigerate for an hour before serving.

Tips for the Best Fudgy Protein Brookies:

  • Don’t Overbake – Brookies continue to set as they cool, so take them out while they’re slightly underdone in the center.
  • Use a Good Protein Powder – A smooth, high-quality protein powder blends better and avoids a chalky texture.
  • Chill for Extra Fudginess – Letting the brookies cool in the fridge before slicing makes them extra gooey.
  • Customize the Flavor – Add a pinch of cinnamon, sea salt, or even espresso powder for a flavor boost.

FAQ: Your Brookie Questions Answered

  • Can I make these vegan? Yes! Swap the egg for a flaxseed egg (1 tbsp ground flax + 3 tbsp water).
  • What’s the best protein powder to use? Awhey or plant-based protein powder with a smooth texture works best. Avoid gritty or overly sweet powders.
  • How do I store them? Store in an airtight container at room temp for 2–3 days or refrigerate for up to 1 week.
  • Can I freeze them? Yes! Slice them and freeze in an airtight container for up to 3 months.
  • How do I make them even fudgier? Use extra chocolate chips, slightly underbake them, and chill them before slicing!
