Preheat oven to 350F and line a baking dish with parchment paper (I use an 8×8 baking dish).
Add all ingredients (except chocolate chips) to a large bowl and mix until fully combined.
Stir in chocolate chips.
Pour batter into baking dish and bake for 30-32 minutes.
Let cool and cut into 9 slices.
Optional to top with powdered sugar.
Enjoy!
