Preheat the oven at 170ºC/ 340ºF conventional oven and prepare 3x 20 cm (8 inch) cake pans lined with parchment paper.
In a large mixing bowl, sift all-purpose flour, baking powder, baking soda and salt. Then add granulated sugar and mix it together so everything has been combined.
340 g all-purpose flour, ¾ teaspoon baking powder, ¾ teaspoon baking soda, ¾ teaspoon salt, 300 g granulated sugar
Then add the butter and with a hand mixer or in a stand mixer, using the paddle attachment, mix it together until the butter has coated the dry ingredient and it looks like a sandy texture.
140 g butter
Then add the eggs, Greek yogurt, milk, oil and vanilla extract and with the electric mixer mix it all together until smooth. Make sure there are no lumps left in the batter.
4 large eggs, 160 g Greek yogurt, 80 g whole milk, 80 g vegetable oil, 1 ½ teaspoon vanilla extract
Divide the batter in the baking pans and top them each with raspberries. Bake them for 22-25 minutes or until a cake tester comes out clean.
200 g frozen raspberries
Let the cakes cool on a wire rack. After 5 minutes, gently remove the cakes from the cake tins and let the cakes cool down completely.
