7 Layer Bar Recipe Martha Stewart: No-Bake Layers of Gooey Goodness

These layered bars bring together sweet, chewy, and crunchy textures in one iconic dessert. I’ve refined this version to ensure every bite delivers the classic combination of chocolate, coconut, and nuts.

The beauty of this recipe is its simplicity—no baking required, just a short time in the oven to set the layers. Each ingredient builds on the last, creating a rich, gooey treat that’s hard to resist.

You’ll end up with a pan of bars that are crisp on top, soft in the middle, and packed with flavor in every layer. They’re perfect for gatherings or a sweet indulgence anytime.

This method guarantees no-bake convenience with a final result that tastes like it came from a professional kitchen.

Ingredients for 7 Layer Bar Recipe Martha Stewart

A handful of pantry staples creates these iconic layered bars with perfect texture contrast.

The graham cracker base sets the tone—Honey Maid or Annie’s brands work well, but any plain variety will do. For the coconut, Baker’s Angel Flake is a classic choice (the good stuff, not the pre-shredded kind with additives). The condensed milk is non-negotiable; Eagle Brand is the standard. Pecans and walnuts should be fresh, so buy from a store with high turnover like Whole Foods or Trader Joe’s.

No butterscotch chips? Peanut butter or white chocolate chips make great substitutes. Short on time? Pre-toasted nuts save a step (just check for added oils). The chocolate chips can be milk or dark, but semi-sweet balances the sweetness best. For a nut-free version, swap in sunflower seeds or pretzel pieces—still gets you that crunch.

These bars keep beautifully at room temperature for 3-4 days in an airtight container. For longer storage, freeze for up to 2 months—thaw overnight before serving. The layers will soften slightly over time, but that’s part of the charm (worth the extra minute to let them sit before cutting).

Step-by-Step Instructions for 7 Layer Bars

Here’s the method. Straightforward, tested, works every time.

Step 1: Create the Graham Cracker Crust Base

Preheat your oven to 350°F. In a medium bowl, combine the 2 cups Graham Cracker Crumbs with the 0.5 cup Unsalted Butter that you’ve melted. Stir until the crumbs are evenly coated and the mixture resembles wet sand.

Press this mixture firmly into the bottom of a 9×13-inch baking pan. I use the bottom of a measuring cup to really pack it down—this creates a solid foundation that won’t crumble when you cut the bars. Bake for 8-10 minutes until the edges start to turn light golden brown.

Step 2: Layer the Chocolate and Butterscotch Chips

Sprinkle the 1 cup Semi-Sweet Chocolate Chips evenly over the hot crust, followed by the 1 cup Butterscotch Chips. There’s no need to press them down—the heat from the crust will soften them slightly, helping them adhere to the base.

Distribute the chips as uniformly as possible to ensure every bite has that perfect chocolate-butterscotch combination. This layer creates the rich, gooey center that makes these bars so addictive. The residual heat from the crust will begin to melt the chips just enough to bind them together.

Step 3: Add the Coconut, Nuts, and Marshmallows

Next, sprinkle the 1.5 cups Sweetened Shredded Coconut evenly over the chips. Then add the 1 cup Chopped Pecans and 0.5 cup Chopped Walnuts in an even layer. The nuts add a satisfying crunch that contrasts beautifully with the chewy layers.

Finish this step by scattering the 0.5 cup Mini Marshmallows and 0.25 cup Old-Fashioned Rolled Oats on top. The marshmallows will melt into gooey pockets, while the oats add a hearty texture that balances the sweetness.

Step 4: Pour the Sweetened Condensed Milk Mixture

In a small bowl, whisk together the 1 can Sweetened Condensed Milk, 1 tsp Vanilla Extract, and 0.25 tsp Salt. Pour this mixture evenly over the entire pan, making sure it seeps into all the layers below.

This is the magic step—the sweetened condensed milk binds everything together and creates that signature caramelized top layer. Use the back of a spoon to gently spread it if needed, but don’t press down too hard. You want the layers to remain distinct.

Step 5: Bake and Cool Completely

Bake for 25-30 minutes or until the top is golden brown and the edges are bubbling. The center should look set but still slightly jiggly—it will firm up as it cools.

Let the bars cool completely in the pan, about 2 hours, before cutting. This waiting period is crucial; if you cut them too soon, they’ll fall apart. Once fully set, slice into squares and serve at room temperature for the best texture.

Make-Ahead Tips for 7 layer bar recipe martha stewart

Prep Ahead Layers

You can measure and chop all your ingredients the night before. Store chopped pecans and walnuts in sealed containers at room temperature, but keep the sweetened condensed milk in the fridge until ready to use. This saves 15-20 minutes on baking day. 💡

Crust First Approach

Prepare and bake the graham cracker crust up to 2 days ahead. Let it cool completely, then cover the pan tightly with plastic wrap. When ready to finish, just add your layers and bake as directed. The crust stays crisp this way.

Full Assembly Ahead

Assemble the entire pan (unbaked) and refrigerate overnight. In the morning, let it sit at room temperature for 30 minutes before baking. The cold layers may need 5 extra minutes in the oven to set properly.

Freeze for Later

Baked and cooled bars freeze beautifully for up to 2 months. Wrap individual bars in parchment, then place in a freezer bag. Thaw at room temperature for 1 hour before serving. They taste almost freshly made.

Portion Control

Cut into bars before freezing for perfect grab-and-go treats. I use a sharp chef’s knife dipped in hot water for clean cuts. Stack with parchment between layers to prevent sticking.

Reviving Leftovers

If bars dry out, warm briefly at 300°F for 5-8 minutes to restore gooeyness. Microwave works too but watch closely—10-15 seconds is often enough. 🔥
