Lemon Cream Crumble Bars with Oats

Tips

Tip 1

Rubbing cold butter with fingertips keeps the crumble texture distinct and prevents dense results.

Tip 2

Refrigerating the crumble mixture before baking helps it stay crispy.

Tip 3

Chilling for the full hour before slicing prevents the filling from smudging and creates cleaner cuts.

Common Mistakes

Watch

Watch

Watch

Do not slice before full refrigeration to avoid filling bleeding into crumble.
