Preparation

Get these tasks done before you start cooking.

Mise en Place

  1. 1

    Prep Pan and Oven

    Preheat your oven to 175 C. Grease a 23 cm springform pan or square baking tin and line the bottom with parchment paper.

    Tip: Using a springform pan makes it much easier to release the fruit-heavy cake without sticking.

  2. 2

    Clean Berries

    Gently wash blackberries and pat them completely dry with a paper towel. Toss them with 1 tablespoon of the measured flour to prevent sinking.

    Tip: Sinking fruit is usually caused by excess moisture or too much weight relative to batter density.

How to Make Blackberry Ginger Sour Cream Cake

Total time: 1 h 15 min · Yields 10 servings

  1. 1

    Whisk Dry Ingredients

    In a medium bowl, sift together the flour, baking powder, baking soda, and sea salt. Set this mixture aside. Ensuring the dry ingredients are well-distributed prevents uneven rising.

  2. 2

    Cream Butter and Sugar

    Using a stand mixer or hand beaters, cream the softened butter and 200 g sugar together until it is pale and fluffy. This should take about 3 to 4 minutes on medium-high speed.

  3. 3

    Incorporate Aromatics

    Add the eggs one at a time, beating well after each addition. Mix in the freshly grated ginger and vanilla extract until fully combined.

  4. 4

    Alternate Flour and Sour Cream

    Reduce the mixer speed to low. Add the dry ingredients in three parts, alternating with the sour cream in two parts, beginning and ending with the flour. Mix only until no white streaks remain.

  5. 5

    Fold in Berries

    Gently fold two-thirds of the blackberries into the batter using a spatula. Be careful not to crush the berries, which would turn the batter purple. Transfer the batter to the prepared pan.

  6. 6

    Apply Topping and Bake

    Press the remaining blackberries into the top of the batter. Mix the topping sugar and ground ginger in a small bowl, then sprinkle evenly over the cake. Bake for 50 to 60 minutes until a skewer comes out clean.

Chef's Tips

  • Always use full-fat sour cream for the best texture. Low-fat versions contain more water and less protein, which can make the cake rubbery.
  • If your blackberries are exceptionally large, slice them in half so they distribute more evenly throughout the crumb.
  • Let the cake cool in the pan for at least 15 minutes before attempting to move it to a wire rack.

What to Serve with Blackberry Ginger Sour Cream Cake

The garlic butter sauce is the star — pick sides that soak it up or balance the richness.

  • Serve warm with a dollop of unsweetened whipped cream.
  • Pair with a scoop of vanilla bean ice cream for a decadent dessert.
  • Enjoy a thick slice alongside a cup of Earl Grey tea.

Recipe Variations

Once you've mastered the base recipe, try these popular twists.

Variation

Substitute blackberries with raspberries for a sharper tartness.

Variation

Add 50 g of chopped crystallized ginger to the batter for extra texture and spicy pops.

Variation

Replace sour cream with Greek yogurt if that is what you have in the fridge.

Storage & Reheating

Store at room temperature in an airtight container for up to 2 days. For longer storage, refrigerate for up to 5 days. This cake freezes beautifully for up to 3 months if wrapped tightly in plastic wrap and foil.

Frequently asked questions

Can I use frozen blackberries?

Yes, you can use frozen berries. Do not thaw them before adding to the batter, as they will bleed color. You may need to add 5-8 minutes to the baking time.

Why is my cake dry?

The most common reason is over-baking or over-mixing the batter. Ensure you stop mixing as soon as the flour disappears and start checking for doneness at the 50-minute mark.

Can I use ground ginger instead of fresh?

You can, but the flavor profile will change. Use 1 teaspoon of ground ginger in the batter as a substitute for 1 tablespoon of fresh, though fresh ginger provides a superior zesty bite.

Does this cake need to be refrigerated?

Because of the high fruit content, if your kitchen is very warm (above 24 C), it is safer to store it in the fridge after the first 24 hours.

My berries all sank to the bottom. What happened?

Your batter might have been too thin, or the berries were too wet. Ensuring the berries are patted dry and tossed in a bit of flour usually prevents this.
