Tips to Make Lemon Crumb Bars
- For a stronger lemon flavor, add a bit more lemon zest to the filling.
- Be careful not to overbake the lemon filling; it should be set but still slightly jiggly in the center when you take it out of the oven.
- Use fresh lemon juice for the best taste.
Variation
You can add a layer of fruit like raspberries or blueberries on top of the lemon filling before baking for a fruity twist on the classic recipe.
