Fudgy Chocolate Tahini Sweet Potato Cake

Jump to Recipe ↓

If you love a rich, brownie-style cake but want something a little more nourishing, this fudgy chocolate tahini sweet potato cake is such a good one to make. It is deeply chocolatey, soft, dense, and sweetened with maple syrup, with sweet potato blended through the batter so it almost disappears into the cake.

As a clinical nutritionist specialising in women’s health, I love recipes like this because they are simple, satisfying, and a practical way to bring more nutrient-dense ingredients into everyday baking. It is also very easy, just mix and bake. No complicated steps, no special equipment, and no need to overthink it.

This cake uses tahini, sesame, sweet potato, cocoa, almond meal and cinnamon, all of which can fit beautifully into a balanced way of eating for women thinking about hormones, cardiovascular health, blood sugar balance, PCOS and menopause. Of course, no single recipe treats a hormone condition on its own, but recipes like this can contribute to greater dietary variety as part of an overall balanced eating pattern. (Bovell-Benjamin, 2007; Hooper et al., 2012; Huang et al., 2022).

Is sweet potato good in baking?

Yes, absolutely. Sweet potato works really well in baking because it adds moisture, natural sweetness and body to the batter. Once it is mixed with cocoa, cinnamon and vanilla, the flavour becomes subtle, while the texture stays soft and dense.

Sweet potato is also known for its carotenoids and polyphenol compounds, which is one reason it is often discussed as a functional food ingredient in nutrition research (Bovell-Benjamin, 2007). Using vegetables in baking can be such an easy way to add more variety to your week, especially if you are baking for kids, family members, or anyone who may not always love vegetables in more obvious forms.

Is tahini good for women’s hormone health?

Tahini is made from ground sesame seeds, so it brings many of the same nutritional qualities as sesame. Sesame seeds contain unsaturated fats, minerals, vitamin E compounds and lignans. Lignans are plant compounds that are often discussed in women’s health nutrition because they may influence oestrogen metabolism and broader cardiometabolic pathways (Wu et al., 2006).

One randomised crossover trial in postmenopausal women found that sesame seed powder intake improved several lipid and antioxidant markers, and may also have influenced hormone-related markers including sex hormone-binding globulin and urinary 2-hydroxyestrone (Wu et al., 2006). While tahini is not a replacement for personalised treatment, it is a beautiful food-first ingredient to include in recipes if you are looking to build more variety into a hormone-conscious diet.

Can sesame seeds support heart health and menopause?

Sesame and tahini are particularly interesting ingredients for women in midlife because they combine healthy fats with plant compounds that have been studied for possible effects on cardiometabolic markers. A meta-analysis of randomised controlled trials found that sesame supplementation improved several cardiovascular risk factors, including blood lipids, blood pressure and body weight markers in some settings (Huang et al., 2022).

That makes sesame a smart ingredient to include in recipes for women wanting food ideas that feel supportive of both heart health and the menopause transition. It is not about one miracle food, but about choosing ingredients that offer more than just sweetness and texture.

Is cocoa actually good for you?

Cocoa is one of my favourite ingredients to use in baking because it adds a lot of flavour while also bringing beneficial polyphenols. A systematic review and meta-analysis found that chocolate, cocoa and flavan-3-ols may improve endothelial function and insulin sensitivity, while also having modest effects on blood pressure in some contexts (Hooper et al., 2012).

That does not mean every chocolate recipe is automatically healthy, but it does support the idea that cocoa-rich baking can offer more nutritional value than highly processed desserts made with very little whole-food input.

What ingredients in this cake may support PCOS and blood sugar balance?

This recipe still sits in the dessert category, but the ingredients are more purposeful than a standard cake made with refined flour and large amounts of sugar. Tahini, almond meal, sweet potato and cocoa all help create a more nourishing base.

Almonds and almond-containing foods have also been studied for cardiometabolic health. A systematic review and meta-analysis found almond intake improved several lipid markers and diastolic blood pressure, which is one reason I like using almond meal in baking where it works well (Morvaridzadeh et al., 2022).

The cinnamon in this recipe is only a small culinary amount, but it is still worth mentioning that cinnamon has been studied in women with PCOS, with meta-analysis data suggesting improvements in insulin resistance markers in some studies (Heshmati et al., 2021). This does not make cake a treatment for PCOS, but it does show how choosing more thoughtful ingredients can be a helpful step in the bigger picture.

What makes this an easy healthy chocolate cake recipe?

This recipe is one of those very practical bakes that feels impressive without being hard to make. It is easy, just mix and bake. Once your sweet potato is cooked, everything comes together in a bowl, and the result is a rich chocolate cake that feels somewhere between dessert and brownie.

I also love that it includes a hidden vegetable without tasting like one. That makes it a great option for anyone wanting a more nourishing bake, or for anyone who loved the fudgy texture of my other brownie-style sweet potato recipes.

Chocolate Sweet Potato Tahini Cake

Makes: 1 x 8-inch cake
Texture: Fudgy, brownie-like
Bake time: Around 1 hour

Ingredients

• 500 g cooked sweet potato (about 2 cups)

• 3 eggs

• 100 g tahini (1/3 cup)

• 60 g coconut oil, melted (1/4 cup)

• 150 mL maple syrup (1/2 cup)

• 1 teaspoon vanilla extract

• 60 g cocoa powder (about 3/4 cup)

• 80 g almond meal (about 3/4 cup)

• 60 g spelt flour (about 1/2 cup)

• 1 1/2 teaspoons baking powder

• 1/2 teaspoon bicarbonate of soda

• 1/4 teaspoon salt

• 1 teaspoon cinnamon

• 1 teaspoon instant coffee powder

Method

If you have not already cooked your sweet potato, this is how I like to do it. Wrap the sweet potato in foil, poke a few holes in it, and bake it at 160°C for about 1 hour, or until very soft. Then peel off the skin. Cooking it this way makes it sweeter and more caramelised.

1. Preheat your oven to 180°C and line an 8-inch cake tin.

2. In a large bowl, mash the cooked sweet potato.

3. Add the eggs and mix well.

4. Add the tahini, melted coconut oil, maple syrup and vanilla, then stir until combined.

5. In a separate bowl, sift together the cocoa powder, almond meal, spelt flour, baking powder, bicarbonate of soda and cinnamon.

6. Stir through the salt and instant coffee powder.

7. Add the dry ingredients to the wet ingredients and whisk until just combined.

8. Pour the batter into the lined cake tin.

9. Bake for around 1 hour, or until a skewer comes out clean.

10. Allow the cake to cool completely before slicing.

Because this is a fudgy cake, it cuts much better once cool, and even better once chilled.

How should you serve this chocolate tahini cake?

You can serve it as is, or with a spoonful of thick Greek yoghurt, a drizzle of extra tahini, fresh berries, or a dusting of cocoa powder. It is rich enough to stand on its own, so even a small slice is satisfying.
