First make the infusion of black tea - in a cup or teapot pour 2 glasses of boiling water over 2 tablespoons of tea leaves. Leave covered for at least 10 minutes.

During this time we prepare the rest of the ingredients - in a bowl put flour, baking powder, sugar and vanilla.

Add the jam, oil, 1.5 glasses of lightly cooled tea - mix well with a whisk.

I put the chopped walnuts.

If the dough is too liquid, add 2-3 tablespoons of flour - I put wholemeal flour.

The crust should be like a thicker cream.

Pour the dough into a tray lined with baking paper, or greased with oil and sprinkled with breadcrumbs.

I put it in the silicone tray, I didn't grease it with anything.

Put it in the oven for 40 minutes at 180 degrees.

After this time, test with a toothpick and if it is good, take it out of the oven.

Allow to cool, then place on a plate or plate.

It is served hot or cold - delicious anyway and a very good taste, it brings grandma's sweets .....

Good appetite!
