Description

These vegan sweet potato brownies are incredibly rich, fudgy, and chocolatey, with mashed sweet potato providing natural sweetness, moisture, and a soft, dense texture. Unlike traditional brownies that rely on eggs and butter, these brownies use sweet potato as the primary binding and moistening ingredient, creating a healthier dessert that remains indulgent and satisfying.

The result is a brownie with a crackly top, a deep chocolate flavor, and a melt-in-your-mouth fudgy center. They’re perfect for dessert, snacks, lunchboxes, or special occasions.

Step 1: Prepare the Sweet Potatoes

Option A: Roast (Recommended)

Preheat oven to:

200°C (400°F)

Wash the sweet potatoes thoroughly.

Pierce each several times with a fork.

Place on a baking tray.

Roast for:

45–60 minutes

until completely tender.

Why Roast?

Roasting concentrates natural sugars and produces a richer flavor than boiling.

---

Option B: Steam

Peel and cube sweet potatoes.

Steam for:

15–20 minutes

until fork-tender.

Allow to cool slightly.

---

Step 2: Mash the Sweet Potatoes

Remove skins if roasted.

Transfer flesh to a bowl.

Mash until completely smooth.

Important

The smoother the sweet potato, the fudgier and more uniform the brownies will be.

For an ultra-smooth texture, use a food processor.

Measure exactly:

2 cups (450 g) mashed sweet potato

---

Step 3: Prepare the Baking Pan

Line an 8-inch square baking pan with parchment paper.

Leave some overhang on the sides.

Lightly grease the paper if desired.

Why?

The parchment allows easy removal and cleaner slices.

---

Step 4: Mix the Wet Ingredients

In a large mixing bowl combine:

• Mashed sweet potato
• Maple syrup
• Plant-based milk
• Melted coconut oil
• Vanilla extract

Whisk until smooth and creamy.

Desired Texture

The mixture should be thick, silky, and evenly blended.

---

Step 5: Combine the Dry Ingredients

In a separate bowl whisk together:

• Cocoa powder
• Flour
• Baking powder
• Salt

Why Mix Separately?

This ensures even distribution of the leavening agent and prevents lumps of cocoa.

---

Step 6: Make the Batter

Gradually add the dry ingredients to the wet mixture.

Fold gently with a spatula.

Mix only until no dry flour remains.

What the Batter Should Look Like

The batter will be:

✓ Thick

✓ Dense

✓ Glossy

✓ Similar to traditional brownie batter

Do not overmix, as this can make the brownies less tender.

---

Step 7: Add Optional Mix-Ins

Fold in:

• Vegan chocolate chips
• Nuts
• Espresso powder
• Cinnamon

if using.

Flavor Tip

Chocolate chips create pockets of melted chocolate throughout the brownies.

---

Step 8: Transfer to the Pan

Spread the batter into the prepared pan.

Use a spatula to level the surface.

Tap the pan gently on the counter to remove large air pockets.

---

Step 9: Bake

Preheat oven to:

175°C (350°F)

Bake for:

25–30 minutes

How to Tell When They’re Done

The edges should appear set.

The center should still be slightly soft.

A toothpick inserted into the center should come out with a few moist crumbs attached.

Avoid Overbaking

Overbaked brownies lose their fudgy texture and become cakier.

---

Step 10: Cool Completely

Place the pan on a wire rack.

Cool for at least:

45–60 minutes

Why This Matters

Brownies continue setting as they cool.

Cutting too early can cause them to crumble.

---

Step 11: Slice

Lift brownies out using the parchment overhang.

Place on a cutting board.

Use a sharp knife to cut into 12 squares.

For cleaner cuts:

• Wipe the knife after each slice.
• Chill brownies for 20 minutes before cutting.

---

Optional Chocolate Glaze

Ingredients

• ½ cup vegan chocolate chips
• 2 tablespoons plant-based milk

Method

Place ingredients in a heatproof bowl.

Microwave in short intervals or melt over simmering water.

Stir until smooth.

Drizzle over cooled brownies.

Allow glaze to set before slicing.

---

Storage
