  • ⅓ cup almond flour (or oat flour for a nut-free option)
  • ⅓ cup maple syrup or honey (for natural sweetness)
  • 2 eggs (or 2 flax eggs for a vegan version)

Notes

Pro Tips for the Best Sweet Potato Brownies:

  • For fudgier brownies: Reduce baking time slightly and let them cool completely before slicing.
  • For cakier brownies: Add an extra ¼ tsp of baking powder.
  • For a richer chocolate taste: Use dark cocoa powder and sprinkle extra chocolate chips on top.
  • To store brownies: Keep in an airtight container at room temperature for 3 days or in the fridge for up to a week.
  • To freeze brownies: Store in a freezer-safe bag for up to 3 months—just thaw for 15 minutes before serving.

Healthy Sweetener Swaps:

  • Mashed bananas instead of maple syrup for a naturally sweet taste.
  • Date syrup for a caramel-like sweetness.
  • Cinnamon & vanilla extract to enhance sweetness without extra sugar.

Best Egg Substitutes for Vegan Brownies:

  • Flax Egg (1 tbsp flaxseed + 3 tbsp water) – Best for moisture & binding.
  • Mashed Banana (¼ cup per egg) – Adds sweetness & softness.
  • Unsweetened Applesauce (¼ cup per egg) – Keeps brownies moist & slightly softer.

How to Store & Reheat:

  • Room temperature: Store in an airtight container for up to 3 days.
  • Refrigerator: Keep in the fridge for up to 7 days.
  • Freezer: Store in a freezer-safe bag for up to 3 months.
  • To reheat: Microwave for 15-20 seconds or bake at 300°F for 5 minutes.
