Low Histamine White Peach Crumble Bars with Cinnamon and Cardamom
Fresh white peaches are one of the gentler stone fruits for anyone managing histamine sensitivity, and pairing them with warm Ceylon cinnamon and cardamom turns a simple filling into something genuinely special. The crust and crumble are built on gluten-free rolled oats, white rice flour, and tapioca starch, so there's no wheat and no fermented or aged ingredients hiding in the mix — just clean, straightforward pantry staples. Cold butter gets worked into that oat mixture until it's shaggy and clumpy, which is exactly what gives you that satisfying crunch on top and a sturdy, press-in base underneath. The peach filling comes together with just a little sugar and tapioca starch to thicken the juices as they bubble in the oven, keeping the ingredient list short and the flavors honest. Baking until the topping is deep golden and the filling is visibly bubbling ensures the bars set up properly — patience during the full cool-down is what makes clean slices possible. Each batch yields 12 bars, so this is a genuinely practical recipe for meal-prepping a week's worth of snacks or bringing something crowd-pleasing to a gathering without stressing over what's in it. The cardamom in particular gives these an almost floral warmth that makes them taste far more complex than the ingredient list would suggest.

Instructions

Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving a 2-inch overhang on the two long sides to use as handles for lifting the bars out later.

In a large mixing bowl, whisk together the rolled oats, white rice flour, tapioca starch (the crust-and-crumble portion), brown sugar, Ceylon cinnamon, cardamom, and salt until evenly combined. Scatter the cold butter cubes over the dry mixture and work them in with a pastry cutter or your fingertips until the mixture resembles coarse, clumpy crumbs with some pea-sized butter pieces remaining — it should hold together when squeezed but still look shaggy.
