Preheat oven to 170°C, line a baking dish and get all your ingredients ready.
Mix all dry ingredients in a bowl (except chocolate chips) and set aside.
Then mix all wet ingredients in another bowl.
Add your dry ingredients to the wet and mix until incorporated.
Fold in chocolate chips.
Pour batter into baking dish and bake ca. 17 minutes, or until a toothpick inserted in the middle comes out clean.
Let cool before slicing.
* Tagatesse is a sweetener that is twice as sweet as regular sugar. If using another sweetener or sugar, you'd want to double the amount used.
** May be substituted with any other oil.
*** I used a piece of sugar free white chocolate cut up into chunks, but regular chocolate chips are fine.
