Sweet potato is a unique vegetable in that it works in both savoury as well as sweet recipes. It has a high sugar content which makes it a great natural sweetener.

Sweet potato brownies ingredients

These healthy sweet potato brownies are also sweetened with a combination of maple syrup and sugar. I used oil rather than butter and added a small amount of baking powder to give these brownies a bit of a lift (otherwise they would be too dense). I also used 2 eggs, dark chocolate along with cacao (use cocoa if preferred) and a handful of chopped pecans for added texture.

How to prepare the sweet potato

To prepare the sweet potato place it on top of a baking sheet and bake in a preheated oven at 200 C until fork tender (30-40 minutes). Remove from the oven and set aside to cool then peel and scoop out the pulp.

Top tip

If using large sweet potatoes I recommend cutting them lengthwise before placing in the oven (to reduce cooking time).

Top tips and FAQs

Sweet potato: I recommend using 2 small sweet potatoes (rather than 1 large) to minimise cooking time.
Make ahead: To save time you can roast the sweet potato ahead. Once it’s cooled you can either refrigerate it for up to 2 days (unpeeled, covered) or puree with the maple syrup before refrigerating.
Chocolate: Use good quality dark chocolate (65 - 75% cocoa solids).
Batter: Do not overmix the batter. Once you've added the dry ingredients stir just to combine.
Storing: Cut into squares and store in an air tight plastic container in the fridge for up to 5 days.
Freeze for up to 3 months.

Substitutions

Cocoa: Either cocoa or cacao powders are fine to use (you might also like this collection of 27 everyday healthy cacao recipes).
Pecans: You could use another soft nut variety, such as cashews, walnuts or even macadamia. Almonds, hazelnuts or brasil nuts are ok to use too but as they are quite tough you might have to chop them a little more finely.
