    Ingredients and substitutions for Strawberry Crumble Bars

    • Strawberries: Fresh or frozen strawberries work well here for the traditional take. You could easily replace with blackberries, apricots, plums or raspberries, virtually any soft fruit would be good in this.
    • Sugar: Superfine or caster sugar works best with the strawberries to draw out the moisture, without adding additional much flavor. The brown sugar helps add a light complimentary flavor to the cinnamon.
    • Oats: Simple rolled oats are used, no quick oats or steel oats which might result in a different texture within the bars.
    • Flour: Plain or all purpose flour is best to create a nice light crumb to our crust and crumble.
    • Butter: Unsalted butter was used here, though salted butter would also work if thatโ€™s what you have on hand and softened will help you create that crumble texture.

    Notes

    • Strawberries: Fresh or frozen strawberries work well here for the traditional take. You could easily replace with blackberries, apricots, plums or raspberries, virtually any soft fruit would be good in this.
    • Baking tin: A square baking tin was used, though a rectangle tin would also work well. Note, the larger the tin from the one used here, the thinner your base and filling will be.
