Ingredients
1. Chocolate Sandwich Cookies
Use about 24 chocolate sandwich cookies. Crush them finely to create the simple cookie crust.
2. Butter
Use 6 tablespoons of melted butter. The butter binds the crushed cookies together and creates a firm base.
3. Chocolate Hazelnut Spread
Use approximately 1 1/2 cups of chocolate hazelnut spread. It provides the rich, creamy chocolate and hazelnut layer that makes these bars so delicious.
How to Make 3-Ingredient Chocolate Hazelnut Icebox Bars
Step 1: Prepare the Pan
Line an 8×8-inch square baking pan with parchment paper, leaving some overhang on the sides for easy removal later.
Step 2: Make the Cookie Crust
Place the chocolate sandwich cookies in a food processor and pulse until finely crushed.
Add the melted butter and pulse or stir until the crumbs are evenly coated.
Press the mixture firmly into the bottom of the prepared pan.
Use the bottom of a glass or measuring cup to create an even, compact layer.
Step 3: Add the Chocolate Hazelnut Layer
Spread the chocolate hazelnut spread evenly over the cookie crust.
For easier spreading, slightly warm the hazelnut spread in the microwave for a few seconds. It should be softened but not hot.
Use a spatula to create a smooth, even layer.
Step 4: Chill
Cover the pan and refrigerate for at least 3–4 hours, or until the bars are firm.
For the cleanest slices, chilling overnight works especially well.
Step 5: Slice and Serve
Lift the chilled bars from the pan using the parchment paper.
Cut into squares with a sharp knife.
For cleaner cuts, wipe the knife between slices.
Tips for Perfect Icebox Bars
Press the cookie crust firmly into the pan. A compact crust will hold together much better when sliced.
Use room-temperature or slightly softened hazelnut spread so it is easier to spread without disturbing the cookie layer.
Give the bars enough time to chill. If they are difficult to cut, return them to the refrigerator for additional time.
For especially neat squares, chill the bars overnight before slicing.
Keep the finished bars refrigerated until ready to serve.
Variations
Hazelnut Crunch Bars
Add chopped toasted hazelnuts over the chocolate hazelnut layer before chilling.
Extra Chocolate
Sprinkle mini chocolate chips over the top before refrigerating.
Dark Chocolate Version
Use a dark chocolate cookie crust for a deeper chocolate flavor.
Individual Icebox Bites
Prepare the recipe in small silicone molds or mini muffin cups for individual portions.
How to Serve
These chocolate hazelnut bars are delicious served straight from the refrigerator.
For an extra-special dessert, serve them with:
- Whipped cream
- Fresh berries
- Vanilla ice cream
- Chopped hazelnuts
- A drizzle of melted chocolate
- Powdered sugar
They also make a great addition to a holiday dessert tray.
Make-Ahead Instructions
These bars are perfect for making ahead.
Prepare them the day before serving and keep them covered in the refrigerator overnight.
This gives the crust plenty of time to firm up and makes slicing easier.
Storage
Store the bars in an airtight container in the refrigerator for up to 5 days.
Keep parchment paper between layers if stacking them.
Can You Freeze Chocolate Hazelnut Icebox Bars?
Yes. Place the chilled bars in a freezer-safe container and separate the layers with parchment paper.
Freeze for up to 2 months.
Thaw in the refrigerator before serving.
Frequently Asked Questions
Do these bars need to be baked?
No. These are completely no-bake icebox bars. The refrigerator firms the cookie crust and chocolate hazelnut layer.
Can I use a different cookie?
Yes. Chocolate graham crackers or another crisp chocolate cookie can be used, although the flavor and texture will vary.
Can I use a larger pan?
You can, but the bars will be thinner. An 8×8-inch pan produces a nice, substantial bar.
Why is my crust falling apart?
The cookie crumbs need to be finely crushed and thoroughly combined with the melted butter. Press the mixture firmly into the pan before adding the hazelnut spread.
How long should the bars chill?
At least 3–4 hours is recommended. Overnight chilling produces particularly firm and easy-to-cut bars.
