This playful baked dessert turns pantry staples into something unexpectedly sweet and crunchy, with dry spaghetti forming the base for an easy sheet-pan treat. It is the kind of recipe that feels a little retro and a little experimental, perfect for National Dessert Day when you want a conversation-starting confection without a long ingredient list or complicated prep.
Serve this dessert in small squares or shards with coffee, hot cocoa, or a scoop of vanilla ice cream. Fresh berries also work nicely alongside it, since their brightness balances the rich sweetness and crisp baked noodle texture.
Butterscotch Spaghetti Crunch Bars
Servings: 8
Ingredients
8 ounces dry uncooked spaghetti, broken in half
1 cup butterscotch chips
3/4 cup creamy peanut butter
3 cups mini marshmallows
1/2 cup unsalted butter, melted
Directions
1. Preheat the oven to 350°F and lightly grease a rimmed sheet pan or line it with parchment paper for easier cleanup.
2. Spread the broken dry spaghetti in an even layer on the sheet pan, drizzle with the melted butter, and toss well so the noodles are lightly coated.
3. Bake for 8 to 10 minutes, stirring once halfway through, until the spaghetti is lightly toasted and fragrant but not dark brown.
4. Remove the pan from the oven, immediately sprinkle the butterscotch chips over the hot noodles, then add the peanut butter in spoonfuls. Let sit for 2 minutes so the heat softens everything.
5. Stir gently to coat the noodles as the butterscotch and peanut butter melt together, then fold in the mini marshmallows.
6. Press the mixture into an even layer in the pan, let it cool until set, then cut or break into bars and serve.
Variations & Tips
Chocolate Swap: Replace the butterscotch chips with semisweet chocolate chips for a more classic candy-bar flavor. The result is a darker, richer finish that pairs especially well with a glass of milk.
Nut-Free Option: Use sunflower seed butter instead of peanut butter if you need a peanut-free version. The texture stays creamy, and the toasted spaghetti still gives the dessert its signature crunch.
Cooling Tip: For the cleanest bars, let the pan cool completely before slicing. If you prefer a more rustic treat, break it into uneven clusters while it is just barely set.
Texture Control: Watch the spaghetti closely in the oven, because it can move from lightly golden to overly browned quickly. You want the noodles crisp and toasted, not deeply browned, so the final dessert tastes nutty rather than bitter.
