Ingredients for Sweet Potato Cake

This recipe makes 12 servings.

• 500 g sweet potato (to yield 300 g purée)
• 3 medium eggs, at room temperature
• 180 g brown sugar
• 190 g olive oil
• 300 g wheat flour
• 10 g baking powder (Royal style)

How to Make Sweet Potato Cake Step by Step

1. Cook and Mash the Sweet Potato

First, wash, dry, and prick 500 g of sweet potato with a knife. Cook it in the microwave at full power for about 8 minutes — the exact time may vary depending on your microwave — until a knife slides in without resistance. Once cooked, cut it in half, scoop out the flesh with a spoon, and mash it with a fork. For this cake, you need 300 g of cooked sweet potato purée.

2. Beat Eggs and Sugar

Preheat the oven to 180 °C (350 °F). In a bowl, beat 3 medium eggs with 180 g of brown sugar for 3 minutes, until the mixture doubles in volume.

3. Add the Olive Oil

Pour in 190 g of olive oil and beat again until the oil is fully incorporated.

4. Incorporate Sweet Potato and Dry Ingredients

Add the mashed sweet potato purée, then gradually incorporate 300 g of wheat flour mixed with 10 g of baking powder, stirring gently until just combined.

5. Fill the Mold

Pour the batter into a 23 x 11 cm loaf pan, smoothing the top with a spatula.

6. Bake and Cool

Bake the sweet potato cake for 1 hour and 15 minutes at 180 °C (350 °F), until a toothpick inserted in the center comes out clean. Remove from the oven, let it rest for 10 minutes, then unmold and let it cool completely on a wire rack.

Tips for the Best Sweet Potato Cake

Customize the Flavor

To personalize this recipe and add a delicious touch, you can add spices to taste. This homemade sweet potato cake is delicious with cinnamon, a pinch of ground cloves, or a little ground ginger — these give it the warm notes typical of cold months. You can also leave it as is to savor the natural nuances of the sweet potato.

Decorating Ideas

As for decoration, we like to leave it natural, but you can dust it with a little powdered sugar if you want a more festive touch.

Serving Suggestions

This sweet potato cake is a great option for a comforting autumn snack. Paired with a coffee with milk, a cup of hot chocolate, or any other warm drink you like, it becomes a comforting pleasure to enjoy on a cold autumn afternoon.

30 Home-Cooked Recipes I Keep Coming Back To

If you're anything like me, your kitchen rotation probably includes a little bit of everything — cozy comfort plates, tried-and-true dishes from around the globe, and sweets that make a crowd happy.

When a rich, indulgent treat is calling my name, I reach for this La Viña Molten Cheesecake recipe, this refined Original French Crème Brûlée recipe, or a luxurious Chocolate Mousse Cake recipe. And on days when only something fruity and soothing will do, this timeless French Tarte Tatin recipe is my go-to.

Mornings and lighter plates call for these airy Oatmeal and Banana Pancakes recipe, a hearty Stuffed Sweet Potato recipe, or these bright Eggs Stuffed with Avocado and Salmon recipe. And for a gluten-free staple I can keep on hand, this no-fuss Gluten-Free Rice Flour recipe does the trick.

Tapas and Mediterranean flavors are a constant craving, so I switch between this punchy Basque Tuna with Tomato recipe, golden Patatas Bravas Air Fryer recipe, silky Tirokafteri Greek Dip Sauce recipe, and a cool Burrata Salad with Tomato and Pesto recipe. And when the occasion begs for something a touch fancier, this elegant Italian Vitello Tonnato recipe is what I serve.

Come lunch or dinnertime, these are the dishes I hand out to friends most often: a soul-warming Meatballs in Spanish Sauce recipe, a time-honored Meatballs in Almond Sauce recipe, a deeply savory Italian Bolognese Sauce recipe, and velvety Chicken Croquettes in Thermomix recipe. For something more substantial, out comes this oven-baked Greek Pastitsio Pie recipe, a homey Potatoes and Squid Stew recipe, or the deeply comforting French Boeuf Bourguignon recipe.

Street-food cravings and party spreads usually mean this succulent Homemade Chicken Doner Kebab recipe, crispy Salchipapas recipe, boldly seasoned Mexican Pork Carnitas recipe, or these crisp Korean Hobak Jeon recipe. These simple Air Fryer Zucchini Rings recipe also make an effortless appetizer or snack.

And when I'm hosting and mixing drinks alongside a full menu, dinner often gets paired with a cool Original Cuban Mojito recipe, a strong Long Island Iced Tea recipe, or a pitcher of this fruity Bleeding Spanish Sangria recipe. To fill out the spread, I like setting out this zesty French Remoulade Sauce recipe on the side, or finishing the table with this eye-catching Mediterranean Black Rice with Squid recipe.

Even More Tasty Recipes to Cook for the Family

After years of cooking, testing, and tweaking in my own kitchen, I've come to believe the greatest dishes are built on three things: simplicity, techniques you can trust, and flavor that really pops.

Every recipe gathered here is one I genuinely cook over and over — whether it's a fast solo meal or a spread I'm putting together for the people I love.

On the sweet side, the rich, silky Orange Chocolate Mousse Recipe is a favorite of mine when I want something that feels fancy yet comes together without fuss. Another dessert I adore is the caramelized Trdelnik Slavic Pastry Recipe, modeled after the celebrated Central European chimney cake. If baking is your thing, knowing how to make syrup for better dessert texture pays off, and my Inverted Sugar Recipe walks through exactly how I do it at home.

When something light and unfussy sounds right, I tend to go with the timeless Italian Caprese Salad Recipe or a flawlessly cooked Simple Poached Egg Recipe. And for cozier, heartier fare, I'm quick to suggest the filling Meatball Sandwich Recipe, the velvety Russian Stroganoff Beef Recipe, and the fast weeknight winner One Pot Pasta Recipe.

Sharing dishes from across the globe is another joy of mine — among them the genuine Sorropotún de Bonito Fish Stew Recipe, golden Chilean Pumpkin Sopaipillas Recipe, and the traditional Spanish Cochifrito Segovian Fried Pig Recipe.

Air fryer cooking is another category I turn to often, since it delivers great texture while saving time. The ones I make most are Air Fryer Pork Ribs Recipe, Air Fryer Chicken Thighs Recipe, Air Fryer Sweet Potatoes Recipe, Air Fryer Baked Potatoes Recipe, Air Fryer Peppers Recipe, Air Fryer Mixed Sandwich Recipe, Air Fryer Toasted Bread Recipe, and Air Fryer Hard-Boiled Eggs Recipe.

And for anyone steering clear of wheat, my cozy Gluten-Free Lasagna Recipe shows that a classic baked pasta can still be rich, cheesy, and completely gratifying without any gluten.
