Cookie bars, sliced pie squares, granola bars and crisped rice treats. Whether topped with a drizzle of chocolate or a crumbly streusel topping, bars are the go-to treats for bake sales and school lunches, perfect for potlucks and office parties, or simply a quick snack when you’re on the run.
Unpretentious and unapologetically old-school, bars are the stuff of Betty Crocker and “The Joy of Cooking,” tapping into our childhood nostalgia for food enjoyed on school buses and at soccer practice. And it seems almost anything counts as a bar, so long as it’s baked or assembled in a casserole dish or baking pan — with plenty of sweetness to spare.
Cookies baked as bars have an almost cakelike quality to them, as oatmeal, peanut butter or chocolate chip cookies are transformed into thick wedges, crisp on top and gooey-soft in the center. Shortbread works well on its own or as a crust supporting a variety of toppings. Cover shortbread with lemon curd and powdered sugar, or glaze it with a thick coating of rich caramel and a sprinkling of coarse sea salt. Adding a touch of baking powder to the shortbread will lighten the crumb, making the cookie base easier to cut into bars.
Or take your favorite granola recipe and convert it into bars. Keep in mind that, as opposed to traditional granola, which is spread out on a sheet pan and slowly toasted, homemade granola bars will require additional baking time to give them a chance to set up, and they will probably be more delicate than the packaged bars you find at the store. Vary the flavorings and sweeteners to suit your tastes and use up ingredients you have on hand.
Depending on the recipe, coconut oil often makes a great vegan substitution for cookies such as shortbread or sables. For a crumbly berry bar, top a sable-inspired cookie base with jam and fresh berries or fruit, then crumble more of the cookie mixture on top. The sweet-tart notes of the fruit complement the richness of the cookie, and your guests might never guess the treat is vegan.
Sometimes the best bars are the ones that require little, if any, effort at all. “No-bake” bars are simple to make, generally calling for just a handful of ingredients. Bind cereal, crumbled graham crackers or cookies with melted marshmallow or peanut butter, pressing the mixture into a baking dish or pan. Top the bars with a layer of chocolate and a scattering of nuts or sprinkles, and refrigerate to set.
While most cookies, pies and even some cake recipes can be converted to bars, keep in mind that as the recipe changes, so too will the baking time and final temperature. Ingredient ratios may also need to be tweaked so the bars bake completely with the proper texture. It’s best to look for established recipes before converting one yourself.
Perhaps best of all, bars are a great kitchen project for kids of all ages, keeping us occupied and providing the perfect school or cubicle snack all at the same time.
Heat the oven to 350 degrees.
In the bowl of a stand mixer fitted with the paddle attachment, or in a bowl using a hand mixer, beat the butter and sugar until creamy, 3 to 4 minutes. Mix the flour and baking powder together and beat into the butter mixture.
Press the dough into the bottom of a 13- by 9-inch baking dish. Bake until golden, 30 to 35 minutes. Cool to room temperature.
Caramel and assembly
In a large saucepan, combine the sugar, water and corn syrup, stirring until the sugar has the consistency of wet sand. Place the saucepan over high heat and cook until the sugar dissolves and begins to boil. Do not stir the sugar, as this may cause it to seize.
While the sugar is cooking, combine the cream and butter in a saucepan over medium heat. Keep an eye on the sugar while you’re heating the cream to keep it from scorching. Cook until the butter melts, stirring it into the cream. When the mixture has come to a simmer, remove from heat.
Continue to cook the sugar until it darkens to a rich caramel color, 7 to 10 minutes — the sugar will darken quickly and noticeably and will smell faintly nutty. Swirl the pan as the sugar darkens to judge the true color of the caramel (the sugar may darken in patches if there are hot spots on the stove). Watch carefully, as the sugar can easily overcook at this point and burn.
As soon as the color is darkened to a rich caramel, remove the pan from the heat and quickly add the cream mixture in a slow, steady stream. The sugar will bubble and steam as the cream is added; be careful as both the mixture and steam are very hot. Carefully stir in the vanilla, then continue to stir until the mixture stops bubbling. Remove from heat and set aside until cool to just warm.
Pour the cooled caramel over the shortbread, using a spatula to push it to the edges of the dish for an even layer. Sprinkle over the coarse salt. Refrigerate until cold, then cut into bars.
