Ingredients You’ll Need
With Nana’s 3-Ingredient Pecan Log, each ingredient truly shines—no fancy extras required! Every component brings its own unique character to the table, creating irresistible flavor and a melt-in-your-mouth texture in every bite.
- Vanilla Wafers: These cookies form the base of the log, bringing sweet vanilla flavor and soft crunch. Crushing them finely ensures a smooth, sliceable texture.
- Sweetened Condensed Milk: Acting as the glue, this rich, creamy milk binds all the ingredients and adds just the right amount of sweetness plus a hint of caramel.
- Finely Chopped Pecans: Pecans contribute nutty crunch and classic Southern flavor. Be sure to chop them small so they blend beautifully with the cookie crumbs.
How to Make Nana’s 3-Ingredient Pecan Log
Step 1: Crush the Vanilla Wafers
The journey starts with crushing the vanilla wafers into fine, even crumbs. A food processor turns this into a quick, satisfying step, but you can also pop the cookies into a zip-top bag and crush them with a rolling pin. Aim for a texture like coarse sand—this ensures your log slices are smooth and cohesive, with no big cookie chunks interrupting that luscious bite.
Step 2: Combine Everything in One Big Bowl
In a large mixing bowl, toss together the crushed vanilla wafers, sweetened condensed milk, and finely chopped pecans. Start off mixing with a big wooden spoon as the mixture will be quite dense and sticky. Gradually, you’ll want to use clean hands—don’t be shy! There’s something wonderfully old-fashioned about mixing this way. You’ll know it’s ready when you can squeeze the mixture together and it holds its shape.
Step 3: Shape Into Logs
Divide the mixture in half and transfer each mound onto a sheet of wax paper. With your hands or a spatula, shape each portion into a firm, even log (about 1.5 inches thick works well). The logs may look rustic at this point, which is perfectly fine. Wrap each log tightly in the wax paper to help them set up nicely in the fridge.
Step 4: Refrigerate to Set
Place your wrapped logs in the refrigerator for at least 2 hours, or until chilled and firm to the touch. Chilling is key here, since it allows the flavors to harmonize and the logs to slice cleanly. If you’re in a hurry, a quick stint in the freezer (about 30 minutes) can help speed things up, but don’t skip this step!
Step 5: Slice and Serve
When ready to serve, simply unwrap the logs and use a sharp serrated knife to cut thin slices. The texture will be soft enough to bite into, yet pleasantly firm with just the right amount of chewiness. Arrange the slices on a platter and watch them disappear. Nana’s 3-Ingredient Pecan Log always gets rave reviews!
How to Serve Nana’s 3-Ingredient Pecan Log

Garnishes
A simple dusting of powdered sugar makes each slice sparkle, while a drizzle of melted chocolate adds a festive touch for special occasions. A few extra chopped pecans sprinkled on top delivers even more nutty crunch and old-school charm. Sometimes, I even add a tiny pinch of flaky salt to bring out the flavors.
Side Dishes
Pairing Nana’s 3-Ingredient Pecan Log with a cup of strong coffee or tea creates the perfect afternoon pick-me-up. For a true dessert spread, serve alongside fresh fruit, a tray of assorted cookies, or a dollop of whipped cream. It sits beautifully beside other classic Southern desserts, making any spread feel extra special.
Creative Ways to Present
For gifting, wrap individual slices in parchment, then tie them with twine for a rustic bakery look. At parties, arrange the slices in a neat circle or a fun zigzag on a favorite platter. If you’re feeling playful, cut the log into bite-sized cubes and skewer them with festive toothpicks—irresistible on a candy tray! However you serve them, Nana’s 3-Ingredient Pecan Log always draws a crowd.
Make Ahead and Storage
Storing Leftovers
You’ll be happy to know that Nana’s 3-Ingredient Pecan Log keeps beautifully for up to a week when wrapped tightly and stored in the refrigerator. The flavors even seem to deepen after a day or two, making leftovers a little hidden gem waiting in the fridge. Simply transfer to an airtight container if you’ve sliced it, to prevent the pieces from drying out.
Freezing
Freezing is a wonderful option if you want to get ahead for the holidays or always have a little treat on hand. After shaping and wrapping the logs, just pop them in a resealable freezer bag. They’ll keep well for up to 2 months. To serve, thaw overnight in the fridge, then slice and enjoy as usual.
Reheating
This is one recipe that doesn’t require reheating—Nana’s 3-Ingredient Pecan Log tastes best served cold directly from the fridge. If you prefer it slightly softer, let the slices rest at room temperature for 10 to 15 minutes. Beyond that, there’s no need to fuss!
FAQs
Can I use different nuts in Nana’s 3-Ingredient Pecan Log?
Absolutely! While pecans provide that signature Southern flavor, you can substitute walnuts, almonds, or even a blend if you want to mix things up. Just be sure the nuts are chopped finely, so every slice holds together well and is easy to bite into.
Is there a way to make it less sweet?
If you want a slightly less sweet version of Nana’s 3-Ingredient Pecan Log, you can use unsweetened vanilla wafer cookies if you find them, or decrease the amount of condensed milk just a touch (by a tablespoon or two). You can also dust the finished slices with a bit of unsweetened cocoa powder for balance.
What’s the best way to crush vanilla wafers?
A food processor is the quickest, most efficient way to get uniform crumbs. If you don’t have one, place the cookies in a sturdy zip-top bag and crush with a rolling pin or even a heavy skillet. The key is to break them down fine enough that the mixture comes together easily.
Can I double or halve the recipe?
Yes, the recipe is very forgiving and flexible. Doubling is perfect for parties or gift-giving—you’ll just end up with four logs. Halve the ingredients for a small batch, and shape a single log or even little balls (perfect for snacking or sharing on a sweet tray).
Do I need to toast the pecans beforehand?
Toasting brings out an extra level of flavor! If you have an extra few minutes, lightly toast the pecans in a dry skillet over medium heat or on a sheet pan in the oven before chopping. Let them cool completely before using to keep the log crisp and fresh.

There’s something so joyful about sharing Nana’s 3-Ingredient Pecan Log with friends and family—a recipe that’s stood the test of time, always simple, always delicious. Whether you’re making it for a holiday, a potluck, or just because you deserve a treat, I hope it brings as much delight to your kitchen as it has to mine.
