Preheat the oven to 180 ° C (top / bottom heat) or 160 ° C (hot air). Mix the flour with the baking powder in a mixing bowl. Add the remaining ingredients, except for the oreo cookies, and mix first on the lowest, then on the highest speed with a mixer.
Roughly chop the biscuits and fold in about half of them. Pour the dough into the greased pan and sprinkle with the remaining biscuits.
Put in the oven and bake for about 20 minutes. Remove the cake from the mold and let it cool down.
