Best Side Dishes for Oatmeal Lemon Cream Bars

- Fresh Salad: A light mixed greens salad with lemon vinaigrette provides a fresh contrast.
- Fruit Salad: A colorful fruit salad can add sweetness and variety, balancing out the tartness of the bars.

Common Mistakes to Avoid
When making Oatmeal Lemon Cream Bars, it’s easy to encounter some common pitfalls. Here are a few mistakes to watch for:
- Skipping the zest: Not adding lemon zest can lead to a lack of intense lemon flavor. Make sure to zest your lemons before juicing them for maximum taste.
- Overmixing the batter: Overmixing can make the bars dense instead of light and crumbly. Mix just until combined for the best texture.
- Using cold butter: Cold butter doesn’t blend well with sugars and dry ingredients, leading to uneven texture. Always melt your butter before mixing it into the dry ingredients.
- Not measuring accurately: Incorrect measurements can throw off the balance of flavors and textures in your bars. Use proper measuring cups and spoons for accuracy.
- Underbaking or overbaking: Baking too little can result in a gooey center, while overbaking makes them dry. Keep an eye on the time and do a toothpick test to check doneness.
