Secret‑Ingredient Chocolate Bundt Cake
A delightful, moist chocolate bundt that steals the spotlight with a surprising twist
Introduction
When we think about chocolate bundt cakes, the image that comes to mind is usually a glossy, chocolate‑freckled masterpiece that feels both decadent and classic. But what if we could elevate that fondness even further by adding an unexpected ingredient that gives the batter extra moisture, a subtle earthiness, and a fat‑rich undertone that keeps the cake from drying out? Enter the Secret‑Ingredient Chocolate Bundt Cake—a recipe that masterfully fuses the familiar world of chocolate bundt with the culinary innovation of mashed potato, courtesy of Victoria Glass, author of Too Good to Waste.
Victoria’s genius lies in turning everyday, often overlooked ingredients into star‑performers. By integrating mashed potato, the cake becomes astonishingly light and moist while providing a subtle nutty crunch thanks to the almond flour. The result? A cruelty‑free, dairy‑based chocolate bundt that even the most discerning palates will adore.
Whether you’re an aspiring home baker or a seasoned enthusiast looking to broaden your repertoire, this simple yet indulgent recipe will inspire you to experiment beyond the conventional.

Ingredient Highlight
Below is an arranged list of each vital component, the role it plays, and a sprinkling of insider tips that can help fine‑tune flavor, texture, or personal preference.
| Ingredient | Quantity | Role | Tips & Tricks |
|---|---|---|---|
| Unsalted Butter | 125 g | Adds richness, binds fat to moisture | Use at room temperature for a smooth paste; substitute with coconut oil for dairy‑free version |
| Caster Sugar | 200 g | Sweetener, provides a quicker dissolve, and helps create a tender crumb | Avoid using brown sugar unless you want a moist, molasses note |
| Plain All‑Purpose Flour | 200 g | Provides structure and a neutral base for mixing | Opt for a low‑bleed blend or a gluten‑free mix if you’re sensitive |
| Baking Powder | 1 tsp | Leavening agent that creates lift while keeping the batter aerated | Ensure the baking powder is fresh, or you’ll risk a flat cake |
| Ground Almonds | 125 g | Adds nutty flavor and extra almond texture | Slightly toast the almonds before grinding to deepen the nutty aroma |
| Mashed Potato | 150 g | Hidden secret ingredient: moisture bearer, neutral flavor | Use freshly cooked fluffy potatoes; avoid cooled potato that’s become dense |
| Large Eggs | 3 | Protein binder that stabilizes the batter and adds structure | Use egg‑sized at room temperature for even distribution |
| Vanilla Bean Paste | 2 tsp | Pure vanilla flavor; a more potent and authentic choice than extract | If unavailable, split a vanilla bean or use vanilla extract in equal measure |
| Dark Chocolate (70%+ Cocoa) | 100 g | Combats starch by drying pull from the flour, giving a smooth, glossy ganache | Coarsely chop for even melting; fresh chocolate does not need to be tempered for ganache |
| Double Cream | 200 ml | Provides richness to the ganache glaze | Use heavy whipping cream if double cream isn’t available; keep chilled |
| Flaked/Sliced Almonds | to garnish | Adds crunch, nutty streets, and visual appeal | Toast almonds lightly before topping to bring out a deeper caramelized flavor |
A quick note: some bakers wonder whether the mashed potato will adversely affect the flaked almond presentation. Cool runs through the final piece of almond garnish, so the cake’s interior will swallow the potato’s moisture wonderfully while the almonds remain crisp on top.
Step‑by‑Step Instructions
1. Prep Work
Heat the oven to 180 °C (160 °C fan) or set to gas 4.
Grease & flour a 25 cm (10 inch) fluted ring cake tin, or any similarly sized bundt tin. Use a silicone paper liner or an oil‑based spray and a whisk of flour for a cleaner release.
2. Whisk the Batter
Whisk all the cake ingredients together until smooth.
In a large bowl, gently cream the softened butter with the caster sugar until pale and fluffy.
Beat in eggs one at a time, ensuring each addition is fully incorporated before adding the next.
Add vanilla bean paste, then sift the plain all‑purpose flour, baking powder, and ground almonds into the mix. Gently fold until just combined—be careful not to over‑mix, which can degrade the delicate crumb.
Fold in the mashed potato, ensuring the lumps disperse. The batter should be pour‑smooth with a slight sheen from the butter.Pour the mixture into the prepared pan.
Gently tap the tin a few times on the counter to remove any air pockets.
Level the top with a palette knife or the back of a spoon.
3. Bake
Bake for 30–35 minutes, adjusting if needed depending on your oven’s quirks. Start checking for doneness at 30 minutes with the skewer test: insert a skewer into the center; if it comes out clean or with a few moist crumbs, the cake is ready.
Remove from oven and let the cake cool in the pan for 10 minutes for stabilization and crumb formation.
After the 10 minutes, carefully lift the cake from the tin onto a wire rack to cool completely.
4. Ganache Icing
Once the cake is cold, create the chocolate ganache icing.
Place the chopped dark chocolate in a heat‑proof bowl.
In a small saucepan, heat the double cream over medium heat until it just reaches a gentle boil, then remove from heat.
Pour the hot cream over the chocolate; let it stand for about a minute so the chocolate melts smoothly.
Whisk gently until the ganache is glossy and fully blended.
Set the ganache to cool to room temperature.
5. Finish
Slowly drizzle the cooled ganache over the top of the cake.
Not all‑at‑once: let it cascade over the sides and deepen at the center.
Once the ganache has set slightly, sprinkle flaked or sliced almonds over the top for a nuts‑crackle finishing touch.Relax and let the cake set for a further 10–12 minutes before serving to allow the ganache to firm up slightly.
Serving Suggestions & Variations
Classic Pairings
| Pairing | Why It Works | How to Serve |
|---|---|---|
| Whipped Cream | Contrasts the ganache’s smoothness and compliments the moist crumb | Lightly sweeten a dollop of freshly whipped cream with a pinch of sea salt and spoon on the side. |
| Boozy Apron | Adds depth; a splash of brandy or chocolate liqueur mingles with the ganache flavors | A small splash of vodka or amaretto on the ganache before it sets, or a drizzle on the serving plate. |
| Fresh Berries | Tartness cuts the richness and adds bright colors | A scatter of fresh raspberries or blackberries atop the cake. |
Ingredient Tweaks
- Spinach‑Infused Sweetness: Swap some of the pistachio or almond flour for roasted spinach puree to add subtle green crunch and additional moisture.
- Nutless Variation: Subtract the ground almonds and simply increase the mashed potato by 50 g to maintain a moist crumb.
- Vegan Conversion: Use a plant‑based butter substitute, oat milk instead of cream, and a flax‑egg or commercial egg replacer.
- Add Spice: Incorporate a pinch of smoked paprika or cinnamon into the batter for a smoky undertone or winter warmth.
Decorating Ideas
- Chocolate Shavings: Rock the cake with dark chocolate shavings on the top for a dramatic flair.
- Salted Caramel Drizzle: A line of salted caramel across the center adds sweetness and savory contrast.
- Edible Gold Leaf: A touch of edible gold leaf on the almond garnish elevates the cake for special occasions.
