Get Ready to Cook!

You are just a few simple steps away from the fudgiest, most delicious pan of Sweet Potato Brownies. Let’s get our ingredients in order.

What to Expect

Time: About 1 hour (includes time for baking the sweet potato).
Difficulty: Very easy! It’s a simple, one-bowl mixing process.

Before You Begin

The foundation of this recipe is a smooth sweet potato purée. You can easily make it by baking a sweet potato until it’s very tender, then mashing the flesh until it’s completely smooth.

The secret to a perfect, fudgy brownie is to slightly underbake them. You’ll know they’re ready when a toothpick comes out with a few moist crumbs attached, but not wet batter.

Most importantly, you must let these brownies cool completely in the pan. This is a crucial step that allows them to set up, ensuring a perfect texture and clean slices. Don’t rush this part!

Let’s Get Cooking! Step-by-Step Guide

Follow these easy steps to make the best Sweet Potato Brownies.

1. Make the Sweet Potato Purée:
If you haven’t already, bake a sweet potato at 375°F for about 30 minutes until very soft. Peel away the skin and mash the flesh in a bowl until you have a smooth purée. Set your oven temperature to 350°F (176°C) for the brownies.

2. Prepare Your Pan:
Line an 8×8-inch baking pan with parchment paper, leaving some overhang on the sides to act as handles for easy removal later.

3. Mix the Wet Ingredients:
In a large mixing bowl, combine the sweet potato purée, maple syrup, almond butter, vanilla extract, and avocado oil. Stir everything together until it’s smooth and well combined.

4. Add the Dry Ingredients:
Sprinkle the cocoa powder, sea salt, and baking powder over the wet ingredients and stir until just combined. Now, add the oat flour and mix until you have a thick, scoopable batter.

5. Assemble and Bake:

6. Bake to Fudgy Perfection:
Place the pan in the center of your preheated oven and bake for 28-32 minutes. The edges should look slightly dry.

7. Cool Completely:
This step is critical! Remove the pan from the oven and let the brownies cool completely in the pan for at least 30-60 minutes. This allows them to set up.

8. Slice and Serve:
Once cooled, use the parchment paper handles to lift the brownies out of the pan. Slice into 9 or 12 squares and enjoy your perfect Sweet Potato Brownies!

Mastering the Dish: Pointers for Perfection & How to Store

A few final tips will ensure your Sweet Potato Brownies are absolutely flawless.

Flour Notes: We found oat flour gave the best texture for this sweet potato brownies recipe, but gluten-free all-purpose flour should also work well.

Serving Suggestion: These brownies are incredible on their own, but serving one slightly warmed with a scoop of dairy-free vanilla ice cream is a truly next-level experience.

Ingredients

Scale

1 cup sweet potato purée

2/3 cup maple syrup

1/2 cup almond butter or peanut butter

1 tsp pure vanilla extract

1 ½ Tbsp avocado oil

1/2 cup cocoa or cacao powder

1/4 tsp sea salt

1 tsp baking powder

2/3 cup oat flour

1/2 cup chopped raw pecans or walnuts

1/4 cup dairy-free chocolate chips (optional)


Instructions

1. To make sweet potato purée, bake a halved sweet potato at 375°F for 25-30 minutes until tender. Peel and mash the flesh until smooth.

2. Adjust oven temperature to 350°F (176°C) and line an 8×8-inch baking pan with parchment paper.

3. In a large mixing bowl, stir together the sweet potato purée, maple syrup, almond butter, vanilla, and avocado oil until smooth.

4. Add the cacao powder, sea salt, and baking powder and stir to combine.

5. Stir in the oat flour until a thick batter is achieved.

6. Transfer the batter to your prepared pan and spread evenly. Top with pecans and optional chocolate chips.

7. Bake on the center rack for 28-32 minutes. A toothpick inserted into the center should come out mostly clean.

8. Let the brownies cool completely in the pan for at least 30-60 minutes before lifting out and slicing.

Notes

Don’t Over-bake: For the fudgiest texture, pull the brownies from the oven when a toothpick has moist crumbs, but not wet batter.

Cool Completely: This is a critical step! The brownies need to cool in the pan to set up properly for clean slicing.

Storage: Store covered at room temperature for up to 3 days, in the fridge for up to a week, or in the freezer for up to one month.
