Once fully cooled, pile the cheese straws onto a white ceramic plate or tuck them into a tin. Store any leftovers (if you somehow don’t eat the whole batch at the counter) in an airtight container at room temperature for up to 3 days.
For the crispiest texture, let them cool completely before sealing the container.
Variations & Tips
For a milder version, cut the cayenne down to 1/4 teaspoon or use a pinch of black pepper instead; you’ll still get great cheesy flavor with less heat. For extra bite, bump the cayenne up to 3/4 teaspoon or add a pinch of smoked paprika (this would technically be a 5th ingredient, so only do it if you’re not strictly sticking to the 4-ingredient idea). If you like a very sharp flavor, use extra-sharp cheddar and make sure it’s freshly shredded from a block so it melts and bakes properly—pre-shredded cheese is often coated with starch and won’t give the same texture.
You can also play with shapes: cut the dough into short sticks, long skinny straws, or even tiny bite-size squares for party snacks. To make ahead, prepare the dough, shape the straws, and freeze them flat on a baking sheet; once firm, transfer to a freezer bag and bake from frozen, adding a couple extra minutes to the bake time.
Food safety tips: Keep the butter and cheese refrigerated until you’re ready to mix the dough, and don’t leave the dough sitting out for hours before baking—mix, shape, and bake within about an hour for best quality. Since these are low-moisture and fully baked until crisp, they’re safe at room temperature for a few days, but always discard if they smell off, taste stale, or lose their crispness and become overly soft or greasy.
