Cocoa and prunes might not be the first flavor combination you think of for a snack cake, but this recipe really pulls it off beautifully. Using prunes as a natural sweetener means there’s no added sugar, giving a rich, moist texture and subtle sweetness that’s just right. This cake is simple to make, relying on pantry staples like oats and yogurt, making it perfect for those quick baking moments when you want something wholesome yet indulgent. I’ve found the oat flour adds a lovely nutty base that pairs well with the cocoa’s deep flavor, and the yogurt keeps the crumb tender without weighing it down. Plus, soaking the prunes before blending helps ensure smoothness throughout the cake, avoiding any unpleasant chunks or dryness. If you’re curious about other naturally sweetened treats, you might enjoy exploring recipes like these rich cocoa almond truffles with no added sugar that share a similar wholesome feel.

Ingredients
- 1 cup (150 g) pitted prunes
- 3/4 cup (180 ml) hot water
- 1 cup (240 g) plain yogurt
- 2 large eggs
- 1 1/2 cups (135 g) oat flour
- 1/3 cup (30 g) cocoa powder
- 1 teaspoon baking powder
- 1 teaspoon vanilla extract
Ingredient Notes
Prunes act as a natural sweetener and add a rich moisture that sugar alone can’t provide. If you prefer, dried figs or dates could also work but may alter the flavor slightly. Oat flour offers a wholesome texture and naturally gluten-free option if you use certified gluten-free oats, making this cake suitable for sensitive diets. Plain yogurt keeps the batter tender and adds just a bit of tang to cut through the cocoa’s richness. Using good-quality cocoa powder (natural or Dutch-processed) makes a noticeable difference in depth of flavor, so don’t skimp here.
Kitchen Tools Needed
- Blender or food processor for smooth prune puree
- Mixing bowls
- Whisk or hand mixer
- 8-inch (20 cm) round cake pan
- Spatula
- Oven thermometer (optional, for oven accuracy)
Step-by-Step Instructions
- Preheat your oven to 350°F (180°C). Line an 8-inch (20 cm) round cake pan with parchment paper or lightly grease it to prevent sticking.
- Place the prunes in a bowl and pour the hot water over them. Let them soak for 10 minutes to soften thoroughly—this helps the blending process and ensures no dry bits remain.
- Transfer the soaked prunes along with the soaking water into a blender. Add the plain yogurt and blend until glossy and smooth, without any chunks. This step is key to avoiding uneven texture in the cake.
- In a large bowl, whisk the eggs and vanilla extract until slightly frothy. Fold in the prune-yogurt mixture until fully combined.
- Sift together the oat flour, cocoa powder, and baking powder to ensure no lumps, then gently stir into the wet ingredients. Mix until just incorporated—overmixing can make the cake dense.
- Pour the batter into the prepared pan, smoothing the top with a spatula. Bake for 28–34 minutes, testing doneness with a toothpick or skewer which should come out clean or with moist crumbs attached. The cake should spring back lightly when pressed.
- Allow the cake to cool completely in the pan before slicing, which helps it set nicely and improves cutting results.
Pro Tips
- Soaking prunes properly is crucial for a smooth batter; skipping this can leave gritty bits.
- Use room temperature eggs to help create a lighter batter and better rise.
- Avoid overbaking—a slightly underdone center keeps the cake moist, but fully set edges prevent crumbling.
- For an extra chocolatey punch, use Dutch-processed cocoa, but reduce baking powder slightly to balance acidity.
- This recipe pairs nicely with creamy or fresh toppings, and for a different take, try combining it with a no-flour cheesecake like the low-carb cottage cheese cake recipe.
Common Mistakes
- Not soaking the prunes enough, resulting in an uneven texture.
- Overmixing the batter which can make the cake heavy or rubbery.
- Baking at too high a temperature causing burnt edges before the center cooks.
- Using sweetened yogurt that adds unwanted sugar and alters flavor balance.
- Cutting the cake before it cools completely, causing crumbling or sticking.
Variations
- Add a teaspoon of cinnamon or espresso powder to the batter for a subtle warm spice or deep coffee flavor.
- Mix in chopped nuts or dark chocolate chips for texture contrast and extra richness.
- Substitute part of the oat flour with almond flour for a nuttier, denser cake.
- Swap vanilla extract for almond extract to complement the prune’s sweetness differently.
Serving Suggestions
Enjoy this cocoa prune snack cake plain or topped with a dollop of whipped cream or fresh berries. It also pairs wonderfully with a cup of tea or coffee for an afternoon treat. For a festive touch, a light dusting of powdered sugar or a simple yogurt glaze adds charm without overpowering its natural sweetness.
Storage Instructions
Store leftovers tightly wrapped at room temperature for up to 2 days. For longer storage, refrigerate the cake covered for up to 5 days. You can also freeze slices individually wrapped in plastic wrap and placed in a sealed bag for up to 2 months.
Reheating Tips
Warm slices gently in a microwave (about 15 seconds) or in a low oven (300°F/150°C) for 5-8 minutes. This refreshes the texture and flavor without drying it out.
