• Preheat oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper.
• Mix dry ingredients: Combine almond flour, cocoa powder, Spirulina/Chlorella powder, baking powder, and salt in a bowl.
• Mix wet ingredients: In a separate bowl, whisk melted coconut oil, maple syrup, eggs (or flax eggs), and vanilla extract.
• Combine: Pour wet ingredients into dry ingredients and fold until just combined. Add optional mix-ins if desired.
• Bake: Pour batter into the pan, smooth the top, and bake for 20-25 minutes.
• Cool: Let brownies cool in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.

Pro Tips

• For a fudgier texture, avoid overmixing and don’t overbake.
• To mask the algae taste, add extra cocoa powder or vanilla extract.
• For a vegan version, use flax eggs and vegan chocolate chips.
