7 Layer Bar Recipe Martha Stewart: Classic Gooey Goodness in Layers

This timeless dessert delivers layers of texture and flavor in every bite. The combination of butterscotch, chocolate, coconut, and nuts creates a treat that’s both nostalgic and irresistibly indulgent.

I’ve refined this version to ensure each layer stands out while blending perfectly with the others. The base starts with a buttery graham cracker crust, followed by carefully arranged ingredients that melt together during baking.

What emerges from the oven is a golden masterpiece with a gooey center and satisfying crunch. The layers maintain their distinct identities while forming a cohesive dessert that’s impossible to resist.

Perfect for gatherings or when you need a taste of childhood comfort. Here’s how to build these bars.

Ingredients for 7 Layer Bar Recipe Martha Stewart

These classic layers create a nostalgic dessert with gooey, crunchy, and buttery perfection in every bite.

The graham cracker crust is foundation—use Honey Maid or Annie’s for consistent texture. Butter quality matters here; Plugrá or Land O’Lakes give the best melt. Coconut should be sweetened and shredded (the unsweetened flakes don’t integrate the same way). For the nuts, Diamond of California walnuts are my go-to—pre-toasted saves time without sacrificing crunch.

No butterscotch chips? Caramel bits work in a pinch, though the flavor shifts slightly. Swap walnuts for pecans or almonds if preferred—just keep the chop consistent. Sweetened condensed milk is non-negotiable for the gooey center; Eagle Brand is the standard. Out of chocolate chips? Chop up a Hershey’s bar instead (semi-sweet or milk both work).

These bars keep beautifully at room temperature for 3-4 days in an airtight container. For longer storage, freeze for up to 3 months—thaw overnight before serving. The layers set as they cool, so resist the urge to cut too soon (worth the extra minute).

Step-by-Step Instructions for 7 Layer Bars

This method ensures even layers and that signature gooey texture in every bite.

Step 1: Create the Graham Cracker Base

Preheat your oven to 350°F. In a medium bowl, combine the 2 cups Graham Cracker Crumbs with the 0.75 cup Unsalted Butter that you’ve melted and slightly cooled. The mixture should resemble wet sand and hold together when pressed.

Press this evenly into a 9×13-inch baking dish, using the bottom of a measuring cup to create a firm, compact layer. I always take an extra moment to ensure the edges are well-defined—this prevents the filling from seeping underneath during baking.

Step 2: Layer the Chocolate and Butterscotch Chips

Sprinkle the 1.5 cups Semi-Sweet Chocolate Chips evenly over the graham cracker base, creating a complete, single layer. Follow with the 1.5 cups Butterscotch Chips, distributing them as uniformly as possible.

Gently press down on both layers to eliminate any gaps. This step ensures every square will have a balanced combination of chocolate and butterscotch. Avoid compacting too firmly, as you want the chips to melt and spread naturally during baking.

Step 3: Add Coconut, Walnuts, and Flour Mixture

Sprinkle 1 cup Chopped Walnuts evenly over the chips, followed by 1 cup of the Sweetened Shredded Coconut (reserve the remaining 1 cup for the final layer). In a small bowl, mix the 0.25 tsp Sea Salt and 2 tbsp All-Purpose Flour, then sprinkle this evenly over the coconut.

The flour helps absorb some of the moisture from the condensed milk, preventing a soggy texture. Press down lightly to set these layers in place before adding the wet ingredients.

Step 4: Pour the Sweetened Condensed Milk and Finish Layers

Evenly drizzle the 1 can Sweetened Condensed Milk over the entire surface, allowing it to seep into the layers below. Add the 1 tsp Vanilla Extract to the remaining 1 cup Sweetened Shredded Coconut, then sprinkle this as the topmost layer.

Press down gently with a spatula to ensure all layers are in contact. The condensed milk will caramelize during baking, binding everything together into that characteristic chewy texture.

Step 5: Bake to Golden Perfection

Bake on the center rack for 25-30 minutes until the edges are deep golden brown and the center is set but still slightly soft to the touch. Rotate the pan halfway through baking for even browning.

Remove from the oven and cool completely in the pan on a wire rack—this takes about 2 hours. Cutting while warm will result in a runny mess; the bars need time to set properly. Once cooled, slice into squares and serve at room temperature.

Flavor Customization for This Recipe

Sweet and Salty Twist

Add ½ tsp flaky sea salt like Maldon on top of the final coconut layer before baking. This enhances the caramelized flavors and balances the sweetness beautifully. The contrast makes every bite more complex.

Nutty Upgrade

Swap walnuts for toasted pecans—their buttery richness pairs perfectly with the chocolate. Toast 1 cup pecans in a dry skillet over medium heat for 3-4 minutes until fragrant. 🌰

Chocolate Lover’s Dream

Replace the butterscotch chips with an additional 1.5 cups white chocolate chips for a triple-chocolate version. The white chocolate adds creaminess without overpowering the semi-sweet layers.

Tropical Infusion

Mix ½ cup dried pineapple (finely chopped) into the coconut layers. This adds a bright, chewy contrast that complements the gooey center. The tropical note is subtle but noticeable.

Spiced Warmth

Add ½ tsp cinnamon and ¼ tsp nutmeg to the graham cracker crust mixture. These warm spices enhance the caramel notes from the condensed milk. A pinch of cardamom works too. ✨

Extra Gooey Center

Drizzle ¼ cup caramel sauce over the condensed milk layer before adding the final coconut topping. This creates an even more decadent, sticky center that oozes with every bite.
