These pecan sandy crumble bars are the kind of low-effort, high-reward dessert that earns a permanent place in a weeknight baking rotation. Using whole pecan sandies cookies as the base gives the bars a buttery, nutty shortcut flavor, while a few pantry staples turn everything into a cohesive, sliceable treat with a crisp top and soft, rich center. It’s a smart semi-homemade dessert that feels nostalgic and a little old-fashioned, much like a cookie bar crossed with a pecan crumble.
Serve these bars slightly warm or fully cooled, depending on whether you prefer a softer or firmer texture. They pair especially well with coffee, hot tea, or a glass of cold milk, and for dessert you can dress them up with a scoop of vanilla ice cream or a spoonful of lightly sweetened whipped cream. If you’re putting together a holiday tray or potluck spread, they also sit nicely beside fruit bars and brownies.
Oven Baked 5-Ingredient Pecan Sandy Crumble Bars
Servings: 12 bars
Ingredients
24 whole pecan sandies cookies
1/2 cup unsalted butter, melted
1 can (14 ounces) sweetened condensed milk
1 cup chopped pecans
1 cup semi-sweet chocolate chips
Directions
1. Preheat the oven to 350°F. Lightly grease an oven-safe metal sheet pan or line it with parchment for easier removal.
2. Arrange the whole pecan sandies cookies in an even layer across the bottom of the sheet pan, keeping them unbroken and fitting them snugly together as much as possible.
3. Drizzle the melted butter as evenly as possible over the cookies, then pour the sweetened condensed milk over the top so it settles into the gaps.
4. Sprinkle the chopped pecans and chocolate chips evenly over the pan, covering the cookie layer well.
5. Bake for 20 to 25 minutes, until the top looks golden, the chocolate is softened, and the condensed milk has bubbled around the edges.
6. Let the bars cool completely in the pan so they can set, then cut into squares or rectangles for serving.
Variations & Tips
Add Coconut: If you like seven-layer-bar flavors, add 1/2 cup shredded sweetened coconut along with the pecans and chocolate chips. It toasts beautifully in the oven and gives the bars a chewier finish.
Try Butterscotch Chips: Swap some or all of the chocolate chips for butterscotch chips for a warmer, caramel-like flavor that works especially well with the pecans and buttery cookies.
Line the Pan Well: Because sweetened condensed milk becomes very sticky as it bakes, parchment paper with a little overhang makes lifting and cutting the bars much easier once they have cooled.
Cool Before Cutting: These bars need time to firm up. If you cut them too early, they will be delicious but messy. For the cleanest slices, cool completely and chill briefly before cutting.
