🍽️ Tips
- Use old-fashioned rolled oats, not instant, for the best texture
- The broiled topping is what makes this cake special—don’t skip it
- Tastes even better the next day as flavors settle
If you want, I can tweak this into a healthier version, eggless version, or a small-batch recipe depending on what you need.
