Tips from leigh Anne
- Use good-quality jam: Since jam is the star of the show, choose a flavor you love and one with great texture. Apricot, raspberry, blueberry, blackberry, strawberry, or even mixed berry all work beautifully. My favorite brand is Bonne Maman.
- Don’t overfill with jam: A thin, even layer of jam is perfect. Too much can make the bars overly sticky and difficult to cut neatly once baked.
- Press the crust firmly: Use the bottom of a measuring cup or glass to gently press the crust into the pan. This helps create an even base that holds together when sliced.
- Line your pan with parchment: Leaving a little overhang makes it easy to lift the bars out of the pan for clean, bakery-style slices.
- Let them cool completely before cutting: As tempting as it is to dive in, letting the bars cool allows the jam to set and gives you clean, beautiful squares.
Frequently Asked Questions
Can I use homemade jam?
Yes! Homemade jam works beautifully in this recipe. Just make sure it isn’t too runny, or the bars may become overly soft. My favorite homemade strawberry jam recipe would work great.
Do jam bars need to be refrigerated?
No refrigeration is needed. Store them in an airtight container at room temperature for up to 3–4 days. If your kitchen is warm, you can refrigerate them to help them stay firm.
Can I freeze jam bars?
Absolutely. Once cooled and cut, place the bars in a freezer-safe container with parchment between layers and freeze for up to 2 months. Thaw at room temperature before serving.
Why did my bars crumble when cutting?
They were likely cut while still warm. Let the bars cool completely so the jam can set and the crust can firm up for clean slices.
These jam bars are a simple, comforting treat that never goes out of style. With a buttery crumb and a sweet layer of your favorite jam, they’re perfect for sharing, gifting, or enjoying with a cozy cup of tea. Passed along to me years ago on a handwritten notecard from a dear friend, this recipe is as meaningful as it is delicious—and one you’ll find yourself making again and again.
