Moist Sweet Potato Brownies Recipe for Rich, Fudgy Treats

Sweet Potato Brownies – ultra-fudgy, gooey, naturally sweetened vegan and gluten-free brownies that let you indulge while keeping things a little healthier. These moist, dense brownies taste like the real thing — even my brownie-obsessed kids loved them.

If you love brownies but want a slightly more nourishing option without sacrificing fudginess, these Sweet Potato Brownies are a winner. Roasted sweet potatoes bring natural caramel sweetness and moisture, nut butter adds body and cocoa provides a deep chocolate flavor.

A touch of melted plant-based butter gives a glossy finish, vanilla rounds out the taste, and dairy-free chocolate chips plus chopped pecans create a wonderful gooey‑and‑crunchy contrast. These brownies are on the healthier side for a treat, yet deliver the rich, fudgy texture of a classic brownie. No one will guess there’s sweet potato inside — they’ll only know they’re delicious.

Why You’ll ❤️ This Recipe

  • Ultra fudgy and gooey
  • Sweetened with maple syrup for a gentler sugar spike
  • Gluten-free and vegan friendly
Four sweet potato brownies topped with pecans, chocolate chunks, and chocolate chips are arranged closely together on a sheet of newspaper. The brownies have a rich, fudgy texture and are generously studded with toppings.

Here’s What You’ll Need

  • Sweet potatoes – Roast until soft and caramelized for deeper flavor and less moisture in the purée.
  • Peanut butter or almond butter – adds structure and richness while keeping the sweet potato as the lead flavor.
  • Maple syrup or agave syrup – complements the natural sweetness of the sweet potatoes.
  • Melted plant-based butter or coconut oil for gloss and richness.
  • Pure vanilla extract (or vanilla bean paste) to deepen flavor.
  • Unsweetened cocoa powder – choose a good-quality Dutch-process option for a darker, smoother chocolate taste.
  • Flour – a small amount of all-purpose or gluten-free flour gives structure; a pinch of baking powder lifts the dense batter slightly.
  • Dairy-free chocolate chips – folded into the batter and scattered on top for melty pockets.
  • Chopped pecans (or other nuts) – toasted for a toasty crunch that pairs beautifully with sweet potato and chocolate.

How to Make These Sweet Potato Brownies

  1. Roast the sweet potatoes in the oven or air fryer until completely soft (a knife should pierce easily). Cool enough to handle, then peel.
  2. Place the sweet potato flesh, peanut or almond butter, maple syrup, melted plant-based butter, and vanilla in a large bowl. Beat with a hand mixer or mash until smooth.

  1. Sift the flour, cocoa powder, baking powder and salt into the bowl and gently mix until combined. Fold in the dairy-free chocolate chips.
  2. Grease an 8-inch square pan and line it with parchment, leaving the paper to overhang the sides. Transfer the batter to the pan and level the top. Scatter the chopped pecans and a few extra chocolate chips over the surface.

  1. Bake in a preheated 350°F (180°C) oven for 25–28 minutes, then transfer the pan to a wire rack and cool for at least one hour. Chilling in the refrigerator makes slicing easier.
  2. Cut into modest squares — these are rich — and serve on their own or with a small scoop of ice cream.

Recipe Notes and Tips

  • Roast time varies with sweet potato size. An air fryer often speeds things up — leave them whole, unpeeled and unpierced for best results.
  • Be patient and let the brownies cool fully before slicing. The vegan batter produces a dense but soft crumb that benefits from chilling.
  • For clean slices, run your knife under hot water, dry it, and wipe between cuts.
  • Store brownies in an airtight container in the fridge for 3–4 days; serve chilled or warmed. Freeze up to three months, though they’re best freshly baked.
  • Customize with cinnamon, pumpkin spice or orange zest for a flavor twist. Swap pecans for walnuts or hazelnuts if preferred.

  • Mixing bowl
  • 8-inch square brownie pan
  • Cordless hand mixer (or whisk)
  • Parchment paper

Ingredients

For the brownies

  • 1 ½ cups (375g) sweet potato purée (about 3–4 medium sweet potatoes)
  • ½ cup (120g) smooth peanut butter or almond butter
  • ½ cup (120ml) maple syrup or agave syrup
  • ¼ cup (57g) plant-based butter or coconut oil, melted
  • 1 tsp vanilla extract or vanilla bean paste
  • ¼ cup (40g) all-purpose flour or gluten-free flour
  • ¼ cup (40g) unsweetened cocoa powder
  • 1 tsp baking powder
  • ¼ tsp sea salt
  • ½ cup (55g) dairy-free chocolate chips

To top

  • ¼ cup (30g) pecans, roughly chopped (optional)
  • ½ cup (55g) dairy-free chocolate chips (optional)

Instructions

  • Preheat oven to 400°F (200°C). Place sweet potatoes on a lined baking sheet and bake about 1 hour or until very soft. Alternatively roast in an air fryer at 400°F (200°C) for 30–40 minutes.
  • Allow the sweet potatoes to cool until you can handle them, then peel. Add the sweet potato flesh, peanut or almond butter, maple syrup, melted plant-based butter and vanilla to a large bowl. Beat or mash until smooth.
  • Sift in the flour, cocoa powder, baking powder and salt. Mix until combined, then fold in the dairy-free chocolate chips.
  • Grease an 8-inch square pan and line with parchment. Transfer the batter to the pan, level, and top with chopped pecans and extra chocolate chips.
  • Bake in a preheated 350°F (180°C) oven for 25–28 minutes (or at 325°F / 160°C in an air fryer). Let cool for at least an hour before slicing.

Notes

NOTE 1: Roast time depends on sweet potato size. Air fryers can be faster — keep potatoes whole, unpeeled and unpierced.

NOTE 2: Oat flour or almond flour can be used as alternatives to all-purpose flour.
