For this layer, start by preheating the oven to 350 degrees Fahrenheit (177 degrees Celsius).
Then, using a spoon or whisk, mix together the dry ingredients such as the all-purpose flour, baking powder, baking soda, salt, cardamom, and sugar.
Then, add in the wet ingredients, such as the eggs and oil, and mix well.
Rinse and chop up the strawberries and add them into the batter and stir well.
Line a 9-inch x 9-inch baking pan with parchment paper, and spray it with oil or cooking spray.
Then, pour the cake batter into the parchment-lined baking pan and bake at 350 degrees for 30 minutes.
Remove from the oven and let cool.
