Easy cake to make from oatmeal and raspberries

Mom made this simple cake and told me the recipe. Ingredients she put in the cake:
125 grams of flour
0.25 teaspoons baking soda
2 pinches of salt
85 grams of oatmeal
100 grams of brown sugar
115 grams of butter
240 grams of raspberries

The oven was preheated to 175 degrees.
Grease the pan.

In a bowl, first mix the flour, baking soda and salt and then stir in the oatmeal and brown sugar, then add the sliced butter and knead it into the ingredients.

Arrange 2/3 of the mixture on the bottom of the baking dish. Put the raspberries evenly on the dough and put the rest of the dough on the raspberries and gently push down with your palm.

The cake was baked in a preheated oven for about 35 minutes or until the cake got a nice golden brown color.

She cut the chilled cakes into pieces and served them on a plate and offered them to me.
The photo shows how good it was.
