How to Make Lemon Oatmeal Crumble Bars
Step 1: Preheat the Oven
Preheat your oven to about 180 °C / 160 °C for convection. Line a square baking pan (about 22–23 cm) with parchment paper for easy removal later.

Step 4: Make the Filling
In another bowl, whisk together the sweetened condensed milk, lemon juice, and lemon zest until smooth and creamy.

Pour the lemon filling evenly over the oat base. Next, sprinkle the remaining crumble mixture on top of the filling.

Place in your preheated oven and bake for about 25–30 minutes or until the topping is golden brown.

How to Perfect Lemon Oatmeal Crumble Bars
Achieving the perfect Lemon Oatmeal Crumble Bars requires attention to detail at every step. Here are some essential tips to ensure your bars turn out delicious every time.
-
Use Cold Butter: Make sure your butter is cold when mixing it into the crumble; this helps create a flaky texture in the topping.
-
Don’t Overmix: When combining ingredients, mix just until combined. Overmixing can lead to dense bars instead of light and airy ones.
-
Zest Fresh Lemons: Use fresh lemons for zest and juice. This brings out the best flavor compared to bottled alternatives.
-
Let Them Cool: Allow the bars to cool completely before cutting. This helps them set properly and makes slicing easier.
-
Store Properly: Keep leftovers in an airtight container in the fridge to maintain freshness and flavor.

Common Mistakes to Avoid
When making Lemon Oatmeal Crumble Bars, it’s easy to slip up. Here are some common mistakes and how to avoid them.
-
Not measuring ingredients correctly: Accurate measurements ensure the right texture and flavor. Use a kitchen scale or measuring cups for precision.

-
Skipping the chilling step: Allowing the bars to cool completely helps them set properly. If you cut them too soon, they may fall apart.

Overbaking: Keep an eye on the bars while baking. They should be golden brown on top; overbaking can lead to dry bars.
