Raspberry Mug Cake with Cream

Sometimes the simplest cakes catch you by surprise—this straightforward sour cream cake with fresh currants is a perfect example. It’s a quick, fuss-free recipe that turns pantry staples and a seasonal fruit into a tender, subtly tangy treat. Using sour cream adds moisture and a delicate richness, while the fresh currants provide a lovely burst of tart flavor that cuts through the sweetness just right. This cake is forgiving and practical, ideal for those afternoons when you want homemade but without complicated steps or fancy ingredients. A light dusting of powdered sugar finishes it off beautifully, lending a touch of elegance with minimal effort.

Baking this cake reveals how easy it is to get a moist, tender crumb while keeping the tone balanced by the currants. Just remember to drain any frozen berries well to avoid a soggy bottom. I often bake it in a round or square pan, and it fares well either way. It’s the kind of recipe you’ll find yourself returning to when you want something simple, reliable, and comforting.

Ingredients

1 cup (120 g) all-purpose flour
1 cup (200 g) granulated sugar
1 cup (240 ml) sour cream
1 large egg
1 cup (about 150 g) fresh currants (or frozen, well drained)
1 teaspoon baking powder
1 teaspoon vanilla extract (optional)
A pinch of salt
Butter or oil, for greasing the pan
Powdered sugar (optional, for dusting)

Ingredient Notes

The sour cream is key for this cake’s tender texture and subtle tanginess. If you don’t have sour cream, you can substitute plain Greek yogurt, but the texture may be a little denser. Fresh currants bring a nice tart contrast, but if you can’t find them, other small berries like blueberries or raspberries work well, too—just watch for extra moisture. Sifting the flour along with baking powder and salt helps avoid lumps and evenly distributes the leavening. Vanilla extract is optional but adds a nice warm note.

Kitchen Tools Needed

Mixing bowl
Whisk or electric mixer
Sifter or fine mesh sieve
Measuring cups and spoons
Baking pan (8-inch round or 8×8-inch square)
Cooling rack
Spatula

Step-by-Step Instructions

Preheat your oven to 350°F (180°C). Grease your baking pan lightly with butter or oil.
In a large mixing bowl, whisk the egg and sugar together until the mixture lightens a bit in color and becomes slightly frothy. This step helps with incorporating air for a light crumb.
Add the sour cream and vanilla extract (if using) to the egg mixture. Stir gently until just combined.
Sift the flour, baking powder, and salt together to ensure even distribution of ingredients and prevent clumps.
Gradually fold the dry ingredients into the wet mixture, mixing with a spatula until just combined. Avoid overmixing here to keep the cake tender.
Gently fold in the currants, trying not to break them up too much. If frozen, make sure they are fully thawed and well-drained to avoid soggy batter.
Pour the batter into the prepared pan and smooth the top evenly.
Bake for 35 to 45 minutes. The cake is done when a toothpick inserted in the center comes out clean or with just a few moist crumbs. You’ll notice the edges pulling away slightly from the pan and a golden color on top.
Let the cake cool in the pan for about 15 minutes before turning it out onto a wire rack to cool completely.
Once cooled, dust with powdered sugar if desired. This adds a pretty finish and a touch of extra sweetness without overpowering the currants.

Pro Tips

Avoid overmixing once you add the dry ingredients; it can make the cake tough.
If using frozen currants or berries, drain them thoroughly and pat dry with paper towels to keep the batter from getting too wet.
Room temperature egg and sour cream blend better, giving a smoother batter and even rise.
Check the cake around 35 minutes to prevent overbaking, as oven temperatures vary.
Use a light hand when folding in the currants to keep them intact and evenly distributed.

Common Mistakes

Not draining frozen berries well enough, which can lead to a soggy cake bottom.
Overmixing the batter after adding flour causes a dense, rubbery texture.
Baking at too high a temperature, resulting in a burnt crust but undercooked inside.
Skipping the greasing step, causing the cake to stick to the pan and break apart.
Attempting to cut the cake before it’s fully cooled, leading to crumbling.

Variations

Swap fresh currants for raspberries, blueberries, or blackberries based on what’s in season.
Add a tablespoon of lemon zest to the batter for a fresh citrus twist.
Stir in a handful of chopped nuts like almonds or walnuts for some added crunch.
Mix in a couple of tablespoons of cocoa powder to the dry ingredients for a chocolate version.

Serving Suggestions

This cake is lovely served plain with a cup of tea or coffee. For a more indulgent treat, add a dollop of whipped cream or a scoop of vanilla ice cream alongside. It’s also great lightly warmed with fresh berries or fruit compote on the side.

Storage Instructions

Once completely cooled, store the cake wrapped loosely in plastic wrap or in an airtight container at room temperature for up to 2 days. You can keep it in the fridge for up to 4 days, but bring to room temperature before serving so the texture is soft.

Reheating Tips

If you prefer your cake warm, gently reheat individual slices in the microwave for 15 to 20 seconds. This softens it just right without drying it out.
