Lemon and Blackberry Cake
This gorgeous Lemon and Blackberry Cake is moist, fruity, and created in one bowl. Filled with vibrant blackberries which can be fresh or frozen, they add a burst of sweetness and tang along with the freshly squeezed lemon juice and zest. This easy lemon and blackberry cake is served with a dusting of icing sugar, if desired.

This recipe is a simple one bowl vanilla cake with a straightforward method. It makes a single layer 8-inch round cake. This size cake is wonderful when you don’t need a multi-layered cake that uses a bulk of ingredients.
Having an easy blackberry lemon cake recipe is perfect to make and enjoy during the warmer summer months when they’re in season. You can also have this blackberry cake during the cooler months and use frozen blackberries.
Including berries in your cakes, cupcakes, and muffins is a delicious way to add freshness and different flavors to your recipes, such as these White Chocolate and Raspberry Muffins.

📋 Ingredient Notes & Substitutions

Plain flour: I use unbleached plain all purpose flour but you can also use just plain all purpose flour.
Unsalted butter: I typically always use unsalted butter in my baking recipes as I like to add salt as a separate ingredient to have more control over the flavor. If you only have salted butter on hand, I suggest omitting the added 1/4 teaspoon salt in this recipe to avoid altering the flavor too much.
Sugar: You can use either golden or white caster/superfine sugar for your cake. I love to use golden as it adds extra flavor and it isn’t as processed as the white version.
Lemon juice: Use freshly squeezed juice from a ripe lemon for this lemon cake. This provides the best and most authentic flavor compared to using store-bought bottled lemon juice.
Blackberries: I used frozen blackberries in my cake but you can also use fresh. If you choose to use frozen blackberries, do not thaw them before, just add them straight from the freezer and into your cake batter.
Icing sugar: There is no frosting for this cake as it shines by itself and its moist texture is enough. I like a light dusting of icing sugar to compliment it, but that is an optional step.
🥣 Step By Step Instructions
1) In a medium size mixing bowl, add flour, baking powder, and salt. Whisk until well combined. Set aside.

2) In a large mixing bowl, using either electric hand beaters or a stand mixer with the paddle attached, add softened butter to the bowl. Beat butter for a few seconds to break it up and it begins to turn creamy. This makes it easier on your beater when the sugar is added.
3) Add sugar and lemon zest. Beat with the butter for 2 minutes until pale and creamy. Scraping down the sides as needed.

4) Add eggs one at a time, beating for 10 seconds after each addition. Scrape down the sides as needed.

5) Pour in milk, oil, lemon juice, and vanilla. Beat for 15 seconds until well combined. Scrape down the sides again.

6) Add half of the dry flour mixture and beat until just combined. Scrape down the sides and add the remaining flour. Beat until incorporated, ensuring not to over-beat, just until the flour has combined.

7) Add blackberries and gently fold through until combined, ensuring not to over-mix. Pour into the lined pan and smooth out the top with a spatula.

8)Press a few extra blackberries on top of the cake batter.
9) Bake for 45-50 minutes, or until a skewer inserted into the middle comes out clean and it’s lightly golden all over. Remove from oven and allow to cool in pan for 15 minutes. Carefully remove from pan and transfer to a wire rack to cool completely.

9) To serve, dust a light layer of icing sugar if desired. Serve and enjoy!

Do not over-mix this cake batter as it will result in a tough texture after baking.
You can use either frozen or fresh blackberries. If using frozen, do not thaw them before adding them to your batter.
Store cake in an airtight container, in a dry dark pantry for 2-3 days. If it’s humid, store it in the refrigerator to help it stay fresh.

Absolutely loved making this cake. Recipe clear and easy to follow. So light and tasty. Great for using the abundance of blackberries this year. I think it would be lovely warm with custard or ice-cream too.
