Ingredients for 4 and 20 blackbirds salted caramel apple pie
These 14 ingredients create the ultimate pie experience—spiced apples, buttery lattice, and gooey salted caramel that'll have everyone asking for seconds.
| Ingredient | Amount | Notes |
|---|---|---|
| Granny Smith Apples 🍎 | 6 medium | Peeled, cored, sliced thin |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| All-Purpose Flour 🌾 | 2 ½ cups | Plus 1 tbsp for dusting |
| Granulated Sugar 🍚 | 1 ½ cups | For filling and caramel |
| Light Brown Sugar 🍚 | ½ cup | Packed, for filling |
| Ground Cinnamon 🌿 | 2 tbsp | For signature spice |
| Salt 🧂 | 1 ½ tsp | Fine sea salt |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Large Eggs 🥚 | 1 whole | For lattice crust |
| Vanilla Extract 🌸 | 1 tsp | Pure vanilla preferred |
| Heavy Whipping Cream 🥛 | 1 cup | For salted caramel |
| Flaky Sea Salt 🧂 | 2 tbsp | For caramel topping |
| Granulated White Sugar 🍚 | 1 ½ cups | For caramel base |
| Dark Rum 🍹 | 2 tbsp | Optional boozy depth |
The apples are non-negotiable. Granny Smiths give that bright, tangy contrast—Honeycrisp or Fuji work too, but stay firm. Whole Foods or local farmers markets have the best selection. Peel and slice them thin (about 1/4-inch) so they cook evenly. The butter? Plugrá or Land O'Lakes unsalted—cold cubes create flaky layers. For the caramel, Domino sugar is my go-to (no clumping), but any granulated works. The rum? Kahlúa or Captain Morgan adds depth, but vanilla extract alone still delivers.
No dark rum? Extra vanilla extract or bourbon works in a pinch. Swapping apples? Braeburns are slightly sweeter, but Granny Smiths are signature. The lattice crust is all about technique—cut strips from a rolled-out dough rectangle, then weave them. No lattice? Use a full crust, but it won't be as pretty. For the caramel, don't rush the simmer—5 minutes of gentle heat prevents graininess. The filling needs a thickener? 1 tbsp cornstarch mixed with 2 tbsp cold water does the trick.
Prep the crust first—it needs 20 minutes of blind-baking to avoid sogginess. Store leftover filling in the fridge for 3 days, but the crust is best fresh. The caramel? Keep it covered at room temp—it’ll stay soft for days. Freeze the whole pie (unassembled) for 2 months. Pro tip: Wrap the lattice pie in parchment before freezing to protect that delicate crisscross. Reheat slices in a 350°F oven for 5 minutes to revive the caramel.
Why You'll Love This Recipe
- No Rolling Required: I swear by this crust—just mix the flour, butter, and ice water until it almost holds together. No food processor, no stress, and no sad, crumbly mess. The secret’s in the cold butter; it’s your shortcut to flaky perfection.
- Salted Caramel Magic: That deep, buttery caramel with a whisper of salt? It’s the star. The Granny Smiths cut through the richness like a cool breeze, and the brown sugar adds this warm, almost spiced depth. Honestly, it’s the kind of pie that makes you reach for seconds without guilt.
- Weeknight or Fancy Table: Same dough, same filling—just different occasions. Need a quick dessert? Serve it warm with vanilla ice cream. Hosting Thanksgiving? Double the crust and add a sprinkle of sea salt for a showstopper. It’s my go-to for lazy nights and special gatherings.
- Leftovers That Don’t Suck: This pie actually improves the next day. The apples soften just enough to soak up the caramel, and the crust stays crisp. I freeze slices too—no reheating needed, just straight from the freezer to the oven. Budget-friendly? Absolutely. But mostly, it’s just reliable.
Step-by-step instructions for 4 and 20 Blackbirds salted caramel apple pie
Here's how to build this showstopper with layers of spiced apples, boozy caramel, and buttery lattice crust.
Prepare the Salted Caramel Filling
In a heavy saucepan, combine the 1.5 cups granulated white sugar, 1 cup heavy whipping cream, and 2 tbsp dark rum. Bring to a boil over medium-high heat, then reduce to medium-low and simmer without stirring for 10-12 minutes until it turns a deep amber color and thickens to 230-235°F on a candy thermometer.
Immediately remove from heat and whisk in 2 tbsp flaky sea salt. The caramel will bubble vigorously—work quickly to avoid splatter. Pour into a greased 9-inch pie dish and let cool completely. This caramel base is the soul of your pie, so don't rush this step. The rum adds depth while the salt creates that perfect balance of sweet and salty.
Assemble the Spiced Apple Filling
In a large bowl, toss the 6 medium peeled, cored, and thinly sliced Granny Smith apples with 1.5 cups granulated sugar, 0.5 cup packed light brown sugar, 2 tbsp ground cinnamon, and 1.5 tsp salt. Let sit for 15 minutes to macerate—this draws out juices and intensifies the flavors. Arrange the apple slices evenly over the cooled caramel layer in the pie dish.
Here's the thing—Granny Smiths can be tart, so the sugar and cinnamon work together to create that perfect balance of sweet and spicy. The salt isn't just for flavor; it helps prevent the apples from turning mushy during baking. Spread the apples in a single layer, pressing down gently to create an even surface.
Create the Lattice Crust
Cut the 1 cup cold cubed unsalted butter into the 2.5 cups all-purpose flour (plus 1 tbsp extra for dusting) until the mixture resembles coarse crumbs with pea-sized butter pieces. Stir in 1 whole large egg and 1 tsp vanilla extract until just combined. Divide the dough into two equal portions, flatten into discs, and chill for 30 minutes.
Roll out one dough disc on a lightly floured surface to 1/8-inch thickness. Using a sharp knife or pizza cutter, make vertical cuts 1/2-inch apart, then horizontal cuts 1/4-inch apart (offset the vertical cuts to create a lattice pattern). Unroll and place over the apple pie, tucking the edges into the pie dish. Repeat with the second dough disc to complete the lattice.
Bake to Golden Perfection
Preheat your oven to 375°F. Bake the pie for 45-50 minutes until the crust is deep golden brown and the filling is bubbling. The lattice should look crisp and slightly puffed. If the crust starts browning too quickly, tent loosely with foil.
Here's where patience pays off: The pie needs time for the apples to soften and the caramel to meld with the filling. When you see the lattice edges turning golden and the filling bubbling through the openings, it's ready. Let cool for at least 2 hours before slicing—this allows the caramel to set properly and prevents a runny mess.
Serve with Confidence
Slice through the lattice crust with a sharp knife, cutting through both layers at once. Serve warm or at room temperature with a scoop of vanilla ice cream. The contrast of the warm pie with cold ice cream is pure magic—each bite delivers that perfect balance of tart apples, rich caramel, and buttery crust.
This pie keeps well for 3 days at room temperature or 1 week refrigerated. The flavors actually improve as the caramel continues to meld with the apples. Store any leftovers covered at room temperature to maintain that perfect texture. Enjoy every last slice—it's worth the effort!
Pro Tips For Making 4 And 20 Blackbirds Salted Caramel Apple Pie
- CHILL THE APPLES: The second you slice those Granny Smiths, toss them in a bowl of ice water. I learned this the hard way—letting them sit too long turns them mushy before they even hit the oven. Even 10 minutes in the fridge makes a real difference in keeping that crisp texture.
- DON’T RUSH THE CARAMEL: Low and slow is the only way with salted caramel. After you melt the butter and sugars, let it bubble gently—no aggressive stirring—until it turns a deep amber. I used to rush it, and the flavor was always flat. Patience here means a richer, less grainy caramel that actually tastes like dessert, not candy.
- SALT THE CRUST: Sprinkle a pinch of flaky salt (or even crushed pretzels, if you’re feeling fancy) on the pie crust before adding the filling. It’s not just for show—it cuts through the sweetness and gives that buttery crust a little crunch. My grandmother swore by this, and she was right: it’s the thing that matters most when you bite into the first slice.
- USE COLD BUTTER: Cut that unsalted butter straight from the fridge into the flour for the crust. Cold butter creates flaky layers, and skipping this step means a tough, dense crust. I was skeptical until I tried it—now I measure it out and keep it in the freezer for 10 minutes before mixing. Yes, even if you’re impatient like me.
Troubleshooting this dish
Caramel Too Runny?
If your caramel isn't thickening enough, you likely didn't reach the right temperature. Use a candy thermometer to monitor the 230-235°F range—this is critical. If it's too thin, simmer uncovered for 5-10 more minutes while stirring occasionally with a silicone spatula.
Avoid adding extra cream; this will dilute the flavor. For an instant fix, whisk in 1 tsp cornstarch mixed with 1 tbsp water to thicken it immediately. 🌡️
Soggy Crust?
A soggy bottom crust usually means the apples released too much liquid or the caramel wasn't fully set. To prevent this, blind-bake the crust for 20 minutes at 375°F with pie weights or dried beans before adding fillings.
If the crust is already soggy, try this: Brush the top with egg wash (1 egg + 1 tbsp water) and bake for 10-15 minutes at 400°F to crisp it up. For future pies, chill the filling for 30 minutes before assembling to reduce moisture.
Apples Not Tender Enough
Undercooked apples often happen when the pie isn't baked long enough or the oven temperature fluctuates. Increase baking time by 10-15 minutes and check the internal temperature—it should reach 190-195°F. For extra tenderness, toss the apples with 1 tbsp lemon juice before baking to soften them faster.
If your oven runs hot, reduce the temperature to 350°F and bake for 5-10 minutes longer. 🍎
Lattice Collapsing?
Lattice crusts can sag if the dough isn't chilled enough or if the pie fills too much. Always chill the dough for 30 minutes before rolling and cutting. When assembling, leave 1-inch gaps between the lattice strips to allow steam to escape.
If it collapses mid-bake, tent with foil and bake for 5-10 more minutes to set it. For extra stability, brush the lattice with egg wash before baking—this adds structure.
Caramel Too Hard?
Overcooked caramel becomes grainy and hard because it cooled too quickly or was stirred too much. To fix it, whisk in 1 tbsp heavy cream to soften it gradually. For future batches, let the caramel cool completely at room temperature before pouring into the pie dish.
If it's already hardened, place the pie dish in a 350°F oven for 5-10 minutes to gently reheat the caramel while keeping the crust intact. 🔥
Filling Spilling Over
Overfilled pies create messy spills during baking. To avoid this, press the apples gently but firmly into the pie dish, leaving ½-inch headspace at the top. If the filling bubbles over mid-bake, use a spatula to push it back down.
For extra insurance, chill the pie unbaked for 15 minutes before placing it in the oven—this helps the filling settle. If it still overflows, bake at 350°F instead of 375°F to slow the cooking process.

Frequently asked questions
Can I make this pie without rum?
The rum adds depth, but you can substitute with 1 tsp vanilla extract or 1 tbsp bourbon for a similar flavor profile. If avoiding alcohol entirely, simply omit it—the caramel will still be delicious, though slightly less complex. The salt and spices will carry the flavor beautifully.
How do I store leftovers?
This pie keeps well at room temperature for 3 days covered loosely with plastic wrap. For longer storage, refrigerate for up to 1 week—the flavors actually improve as the caramel continues to meld with the apples. To reheat, warm slices in a 350°F oven for 5 minutes to revive the caramel. Freezing isn't recommended as it can make the lattice crust soggy.
What's the best way to serve this pie?
Serve warm with a scoop of vanilla ice cream for the perfect contrast, or at room temperature with a dollop of whipped cream. For extra flair, sprinkle with toasted pecans or a pinch of flaky sea salt. The warm pie with cold ice cream creates the ultimate texture experience—crisp lattice, tender apples, and gooey caramel all in one bite.
Can I make the caramel ahead of time?
Yes! Prepare the caramel up to 3 days in advance and store it at room temperature in an airtight container. Let it cool completely before pouring into the pie dish to prevent melting. The flavor actually develops more over time, making it even richer. Just be sure to let it sit at room temperature for 30 minutes before assembling the pie to soften slightly.
Why does the recipe call for both granulated and brown sugar?
The combination creates the perfect balance of flavors. Granulated sugar helps caramelize the apples for that signature sweetness, while brown sugar adds depth and moisture to prevent the filling from drying out. The brown sugar also enhances the caramel's richness, making each bite more complex. It's a classic pairing in apple desserts that elevates this pie beyond basic recipes.
