Sweet potato yoghurt brownies combine the natural sweetness and creaminess of sweet potatoes with tangy yoghurt to create a moist, fudgy dessert that feels indulgent yet wholesome. This recipe works beautifully by replacing some of the butter and eggs with sweet potato and yoghurt, resulting in brownies that are rich in flavor, have a tender crumb, and a subtle nutritional boost.
Ingredients
- 1 cup (240g) cooked and mashed sweet potato (about 1 medium sweet potato)
- 1/2 cup (120g) plain Greek yoghurt (full-fat preferred)
- 3/4 cup (150g) granulated sugar
- 1/4 cup (55g) brown sugar, packed
- 2 large eggs
- 1/3 cup (30g) unsweetened cocoa powder
- 1/2 cup (65g) all-purpose flour
- 1/4 teaspoon baking powder
- 1/4 teaspoon salt
- 1/2 cup (115g) unsalted butter, melted and slightly cooled
- 1 teaspoon vanilla extract
- 1/2 cup (90g) chocolate chips or chopped dark chocolate (optional)
Instructions
- Preheat your oven to 350°F (175°C). Line an 8×8-inch (20×20 cm) baking pan with parchment paper, leaving some overhang for easy removal.
- Prepare the sweet potato by baking, steaming, or microwaving until tender. Peel and mash until smooth. Measure out 1 cup for the recipe.
- In a large mixing bowl, whisk together the mashed sweet potato, Greek yoghurt, granulated sugar, brown sugar, eggs, melted butter, and vanilla extract until smooth and well combined.
- In a separate bowl, sift together the cocoa powder, flour, baking powder, and salt to ensure even distribution.
- Gradually fold the dry ingredients into the wet mixture using a spatula, mixing just until no streaks remain. Avoid overmixing to keep brownies tender.
- Fold in the chocolate chips or chopped chocolate if using, reserving a few to sprinkle on top if desired.
- Pour the batter into the prepared pan and smooth the top evenly. Sprinkle any reserved chocolate pieces on top.
- Bake for 25-30 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs but no wet batter. Baking times may vary slightly depending on your oven.
- Allow the brownies to cool completely in the pan on a wire rack before lifting out using the parchment overhang. Cut into 9-12 squares and serve.
Tips
- Sweet potato prep: Baking or steaming the sweet potato retains moisture and sweetness best. Avoid boiling as it can make the potato waterlogged.
- Yoghurt choice: Full-fat Greek yoghurt adds creaminess and richness. You can substitute with plain regular yoghurt, but the texture may be slightly less dense.
- Flour alternatives: For a gluten-free version, replace all-purpose flour with an equal amount of gluten-free flour blend. Add a pinch more baking powder if needed.
- Storage: Store brownies in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. Freeze for longer storage (see below).
- Don’t overbake: Sweet potato adds moisture, so test early to avoid dry brownies. The toothpick test is key—some moist crumbs are perfect.
Serving Suggestions
These sweet potato yoghurt brownies are delicious on their own or served slightly warm. For an extra touch, try topping them with a dollop of whipped cream or vanilla ice cream. A drizzle of caramel or chocolate sauce complements the earthy sweetness of the sweet potato beautifully. They also pair well with a cup of coffee or a glass of cold milk for a comforting snack or dessert.
Variations
You can easily customize this recipe to suit different tastes and dietary needs. Add chopped nuts such as walnuts or pecans for crunch and nuttiness. Stir in dried fruits like cranberries or raisins for a chewy contrast. For a spiced version, mix in 1/2 teaspoon ground cinnamon and a pinch of nutmeg or allspice. Vegan adaptation can be made by using flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) and a plant-based yoghurt, though texture may vary slightly.
Storage and Reheating
Store leftover brownies in an airtight container at room temperature for up to 3 days. To extend freshness, refrigerate for up to 7 days. For longer storage, wrap brownies individually in plastic wrap and place in a freezer-safe container or bag; they freeze well for up to 3 months.
To reheat, warm brownies in a microwave for 15-20 seconds or in a preheated 300°F (150°C) oven for about 5 minutes until just warm. Avoid overheating to keep the fudgy texture intact.
Frequently Asked Questions
Can I use canned sweet potato instead of fresh?
While canned sweet potato puree can be used in a pinch, fresh cooked sweet potato generally provides better texture and flavor. If using canned, make sure it is unsweetened and plain, and drain any excess liquid before measuring.
Why is yoghurt used in this brownie recipe?
Yoghurt adds moisture and acidity, which tenderizes the batter and balances the sweetness. It also contributes to a richer texture and can reduce the need for excess fat or eggs, making the brownies lighter but still fudgy.
Can I make these brownies gluten-free?
Yes, substitute the all-purpose flour with a gluten-free flour blend that includes xanthan gum or a similar binder. The texture might be slightly different, but the brownies will still be delicious.
How do I know when the brownies are done?
Insert a toothpick into the center of the brownies. It should come out with a few moist crumbs but no wet batter. Because of the sweet potato’s moisture, the brownies may look softer than traditional ones, so err on the side of slightly underbaking rather than overbaking.
Can I add other mix-ins besides chocolate chips?
Absolutely! Nuts, dried fruits, or even swirls of peanut butter or cream cheese can be folded into the batter before baking. Just be mindful of the added moisture or fat and adjust baking time accordingly.
Is this recipe suitable for meal prep or lunchbox treats?
Yes, these brownies keep well and travel nicely, making them a great option for packed snacks or lunchboxes. Their natural sweetness and nutrient boost from sweet potato also make them a more wholesome choice compared to standard brownies.
By following this sweet potato yoghurt brownies recipe, you’ll enjoy a dessert that’s moist, flavorful, and a little more nutritious than your average brownie. Whether you’re looking for a way to use up leftover sweet potatoes or want to experiment with healthier baking swaps, this recipe offers a delicious way to indulge.
For an added nutritional boost, try topping your brownies with a sprinkle of chia seeds or a dollop of nut butter. These additions complement the earthy sweetness and can help keep you fuller longer. Enjoy experimenting with this versatile recipe!
