Lemon crumb bars are a delightful treat that bring a touch of sunshine to any table, especially during the long winters here in the Midwest. This recipe has been passed down through generations in my family, and it always reminds me of my grandmother’s kitchen, where the scent of fresh lemons would mingle with the warmth of the wood-burning stove. These bars are perfect for those who love a balance of sweet and tart, and they make a wonderful addition to any gathering or a simple afternoon tea.
