Seven layer bars are a decadent dessert comprised of seven distinct layers, hence the name. The base is a buttery graham cracker crust, followed by layers of chocolate chips, butterscotch chips, shredded coconut, walnuts (or pecans), and sweetened condensed milk. The condensed milk acts as a binder, caramelizing in the oven to create a gooey, irresistible treat.

## Ingredients You’ll Need

Before you start, gather these ingredients:

* **Graham Cracker Crumbs:** 1 1/2 cups (about 12 graham crackers, finely crushed)
* **Unsalted Butter:** 1/2 cup (1 stick), melted
* **Sweetened Condensed Milk:** 1 (14-ounce) can
* **Semi-Sweet Chocolate Chips:** 1 cup
* **Butterscotch Chips:** 1 cup
* **Shredded Coconut:** 1 1/3 cups (sweetened or unsweetened, to your preference)
* **Chopped Walnuts or Pecans:** 1 cup (or a mix of both)
* **Optional: Pinch of Sea Salt:** Enhances the flavors

## Equipment

You’ll need the following equipment:

* **9×13 inch Baking Pan:** Essential for baking the bars.
* **Mixing Bowl:** For combining the graham cracker crumbs and melted butter.
* **Measuring Cups and Spoons:** For accurate ingredient measurements.
* **Parchment Paper:** To line the baking pan for easy removal and cleanup (optional).
* **Rubber Spatula or Spoon:** For spreading the sweetened condensed milk.

## Step-by-Step Instructions

Follow these detailed instructions to create perfect seven layer bars:

### Step 1: Prepare the Graham Cracker Crust

1. **Preheat Oven:** Preheat your oven to 350°F (175°C).
2. **Crush Graham Crackers:** If using whole graham crackers, crush them into fine crumbs using a food processor or by placing them in a ziplock bag and crushing them with a rolling pin.
3. **Combine Crumbs and Butter:** In a mixing bowl, combine the graham cracker crumbs and melted butter. Mix thoroughly until the crumbs are evenly moistened.
4. **Press into Pan:** Press the mixture firmly and evenly into the bottom of the 9×13 inch baking pan. You can use the bottom of a measuring cup or a flat-bottomed glass to help compact the crust.

### Step 2: Layer the Ingredients

1. **Chocolate Chips:** Sprinkle the chocolate chips evenly over the graham cracker crust.
2. **Butterscotch Chips:** Sprinkle the butterscotch chips evenly over the chocolate chips. Try to distribute them so they’re not all clumped together.
3. **Shredded Coconut:** Spread the shredded coconut evenly over the butterscotch chips. If you’re using sweetened coconut, consider reducing the amount of sweetened condensed milk slightly.
4. **Chopped Nuts:** Sprinkle the chopped walnuts or pecans (or a mix) evenly over the coconut. If you like, you can lightly toast the nuts before adding them for a richer flavor. Toast them in a dry pan over medium heat for about 5-7 minutes, or in the oven at 350F for 8-10 minutes, watching carefully to prevent burning.
5. **Sweetened Condensed Milk:** Pour the sweetened condensed milk evenly over all the layers. Use a rubber spatula or spoon to spread it to all edges of the pan, ensuring everything is well-coated. This is crucial for binding the layers together.
6. **Optional Sea Salt:** Sprinkle a pinch of sea salt over the top to enhance the sweetness and other flavors.

### Step 3: Bake

1. **Bake:** Place the baking pan in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the sweetened condensed milk is bubbling.
2. **Check for Doneness:** The bars are done when the edges are set and the center is slightly soft but not liquid.

### Step 4: Cool and Cut

1. **Cool Completely:** Remove the bars from the oven and let them cool completely in the pan. This is very important, as the bars need time to set. Cooling may take 2-3 hours at room temperature, or you can speed up the process by refrigerating them for at least an hour.
2. **Cut into Squares:** Once the bars are completely cool, cut them into squares. For clean cuts, use a sharp knife and wipe it clean between each cut. If you lined the pan with parchment paper, you can lift the entire slab of bars out of the pan before cutting.

## Tips for Perfect Seven Layer Bars

* **Don’t Overbake:** Overbaking can result in hard, dry bars. Keep a close eye on them and remove them from the oven when they are golden brown and the condensed milk is bubbling.
* **Use Quality Ingredients:** The better the quality of your ingredients, the better the bars will taste. Opt for good quality chocolate chips, fresh nuts, and flavorful coconut.
* **Press Crust Firmly:** A firm crust is essential for supporting the layers. Make sure to press the graham cracker mixture evenly and firmly into the pan.
* **Even Distribution of Layers:** Spread each layer evenly over the preceding one to ensure a consistent texture and flavor in every bite.
* **Cool Completely:** As mentioned before, allowing the bars to cool completely is crucial. This prevents them from being too gooey and difficult to cut.
* **Lining the Pan:** Lining the pan with parchment paper makes removing the bars much easier and prevents sticking. Leave an overhang of parchment paper on the sides of the pan to easily lift the bars out.
* **Sweetened vs. Unsweetened Coconut:** If you prefer a less sweet bar, use unsweetened shredded coconut. Otherwise, sweetened coconut works perfectly well.

## Variations and Substitutions

Seven layer bars are incredibly versatile. Here are some ideas for variations and substitutions:

* **Different Chocolate Chips:** Use milk chocolate chips, dark chocolate chips, white chocolate chips, or even a combination of different types of chocolate chips.
* **Different Nuts:** Substitute pecans for walnuts, or use slivered almonds, macadamia nuts, or cashews.
* **Dried Fruit:** Add a layer of dried cranberries, raisins, or chopped apricots for a chewy, fruity twist.
* **Pretzel Pieces:** Add a layer of crushed pretzel pieces for a salty-sweet flavor combination.
* **Peanut Butter Chips:** Substitute peanut butter chips for butterscotch chips.
* **Oatmeal:** Add a layer of rolled oats for a chewier texture and a hint of nutty flavor.
* **Different Crust:** Instead of a graham cracker crust, try using a shortbread crust or a cookie crumb crust made from chocolate cookies.
* **Espresso Powder:** Add a teaspoon of espresso powder to the sweetened condensed milk for a mocha-flavored bar.
* **Spices:** Add a pinch of cinnamon, nutmeg, or allspice to the graham cracker crust or sprinkle over the top layer for added warmth and flavor.
* **Vegan Seven Layer Bars:** Use vegan graham crackers, vegan butter, vegan chocolate chips, and coconut condensed milk to make a vegan version of this classic dessert.

## Serving Suggestions

Seven layer bars are perfect for:

* **Dessert:** Enjoy them as a simple and satisfying dessert.
* **Parties and Gatherings:** They are always a hit at parties, potlucks, and holiday gatherings.
* **Gifts:** Package them in a decorative box or tin for a thoughtful homemade gift.
* **Snacks:** They make a great afternoon snack or a sweet treat to satisfy your cravings.

## Storage Instructions

* **Room Temperature:** Store seven layer bars in an airtight container at room temperature for up to 3-4 days.
* **Refrigerator:** For longer storage, store them in an airtight container in the refrigerator for up to a week. The bars may become slightly firmer in the refrigerator, but they will still taste delicious.
* **Freezer:** You can also freeze seven layer bars for up to 2-3 months. Wrap them tightly in plastic wrap and then place them in a freezer-safe bag or container. Thaw them in the refrigerator before serving.

## Troubleshooting Guide

* **Bars are too hard:** You may have overbaked them. Be sure to keep a close eye on them and remove them from the oven when they are golden brown and the condensed milk is bubbling. Also, make sure you are using the correct oven temperature.
* **Bars are too gooey:** You may not have baked them long enough, or you may not have let them cool completely. Bake them for a few more minutes, and make sure to let them cool completely before cutting.
* **Crust is too crumbly:** You may not have used enough butter in the crust, or you may not have pressed it firmly enough into the pan. Use a little more butter next time, and make sure to press the crust firmly into the pan.
* **Layers are not sticking together:** Make sure you are spreading the sweetened condensed milk evenly over all the layers. This is crucial for binding the layers together.
* **Bars are burning on the edges:** Lower the oven temperature slightly and bake for a longer period of time. You can also tent the pan with aluminum foil to prevent the edges from burning.
