Description
This is the butter cake that I cannot stop making. A soft, tender butter cake, made with sour cream for moisture, with an impossibly light and fluffy crumb. I finish mine with sugar for a crunchy finish, but this cake is the perfect base recipe you will find yourself turning to again and again.
Ingredients
- 150g unsalted butter, at room temperature
- 320g granulated sugar
- 1 Tbsp vanilla extract or vanilla bean paste
- 2 large eggs (about 110g, not including the shell), at room temperature
- 165g sour cream, at room temperature
- 250g all-purpose flour
- 3/4 tsp baking powder
- 1/2 tsp kosher salt (use less if you are using table salt or salted butter)
- Extra granulated sugar for sprinkling on top of the cake (optional)
Instructions
- Preheat the oven to 330°f / 165°c. Grease and line a 9" (23cm) square baking pan, extending the parchment paper over the edges of the pan so that you can use them as a sling later to remove the cake. I like to clip down the edges with little binder clips.
- In the bowl of a stand mixer or in a large bowl using an electric mixer, cream together the butter, sugar, and vanilla on medium to high speed until very light and fluffy. Add the eggs one at a time, mixing to combine between each, then beat the mix for a further 2-3 minutes on high speed until it has thickened up, and is very light.
- Measure out the sour cream into a small bowl. In a medium bowl, combine the flour, baking powder, and salt.
- Alternately add the flour mixture and the sour cream, starting and ending with the flour - add the flour in three additions and the sour cream in two, and briefly mix between additions. Switch to a spatula and give the mixture a few turns to ensure that it is evenly mixed.
- Transfer the mix to the prepared pan and smooth down with a spatula or the back of a spoon, making sure that there are no large air bubbles in the mixture.
- Sprinkle the top with extra granulated sugar if using.
- Bake the cake for 45-50 minutes, until the middle springs back when lightly pressed with a finger, and a skewer inserted into the middle of the cake comes out clean or with a few moist crumbs attached.
- Remove the cake from the oven and leave to cool in the pan for 15-20 minutes, then use the parchment paper sling to remove it from the pan and allow it to cool completely on a wire rack.
- Store the cake at room temperature in an airtight container for up to 4 days.
Notes
To make a peach and passionfruit version: I baked mine in a 10" (25cm) pan, and topped with sliced canned peaches (I used 4 large halves) which I patted dry with a paper towel before slicing. The cake took about 55 min to bake to account for the extra moisture / weight from the peaches. When it was hot from the oven I added passionfruit ice cream topping (I used the Delmaine one), but covering it with a jam of your choice would also work perfectly, or it is very delicious just with a sprinkle of powdered sugar!
