Ingredients for mountain dew pie
Eight slices of nostalgia: soda-infused custard, citrus swirls, and buttery crumb perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Mountain Dew Soda 🥤 | 1 ½ cups | Original flavor, chilled |
| Large Eggs 🥚 | 4 whole | Room temperature preferred |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| All-Purpose Flour 🌾 | ½ cup | For thickening custard |
| Unsalted Butter 🧈 | ¾ cup | Cold, cubed for crumb topping |
| Light Brown Sugar 🍚 | ½ cup | Packed, for crumb topping |
| Old-Fashioned Rolled Oats 🥣 | ½ cup | Quick or old-fashioned |
| Chopped Pecans 🥜 | ¼ cup | Toasted for extra flavor |
| Salted Butter 🧈 | 1 sheet | For pie crust (2 tbsp) |
| All-Purpose Flour 🌾 | 2 ½ cups | Plus 1 tbsp for crust |
| Ice Water 💧 | ½ cup | For pie crust |
| Cornstarch 🌾 | 2 tbsp | For filling stability |

The Mountain Dew is the heart of this pie, so grab a 2-liter bottle from any major grocery store—Walmart or Target always have it stocked. Use the original flavor; nothing else captures that exact citrus-orange tang. For the pie crust, Kirkland Signature unsalted butter (if available) or Land O'Lakes works perfectly. If you're making the crumb topping ahead, toast the pecans in a dry skillet for 2-3 minutes—they add a depth that raw pecans can't match. The custard mixture needs to be smooth and lump-free, so whisk vigorously after adding the cornstarch.
No Mountain Dew? Fanta Orange or Sprite with a splash of lemon-lime soda comes closest, though the flavor won't be identical. Short on pecans? Chopped walnuts or almonds work, but toast them first. The pie crust can be store-bought if you're short on time—Pillsbury Golden Flake is a reliable shortcut. For the crumb topping, if you don't have old-fashioned oats, quick oats work in a pinch, though they'll be slightly finer. The custard should be thick but pourable—if it's too thin, add 1 tsp cornstarch mixed with 1 tbsp cold water and whisk it in.
This pie tastes even better after 4-6 hours in the fridge, so plan ahead. Store leftovers covered at room temperature for up to 2 days or refrigerate for 4 days. The crumb topping hardens as it cools, so reheat slices at 350°F for 5-7 minutes to restore that buttery crunch. For serving, whipped cream or caramel drizzle elevates it to restaurant-quality. Freeze individual slices wrapped in plastic for up to 2 months—just thaw at room temperature before serving.
Why You'll Love This Recipe
- I’ll be real: Mountain Dew isn’t cheap, but you only need one can for this recipe. The rest of the ingredients—flour, sugar, butter—are already in my cupboard. It’s the kind of treat that feels special without breaking the bank, and slices reheat beautifully for days.
- Pie in 30 Minutes: I swear, this pie comes together faster than you can finish a can of Mountain Dew. Just mix the soda into the batter—no waiting for it to settle, no measuring out weird ratios. The eggs and sugar do all the heavy lifting while you butter up that crust in record time.
- Nostalgia in Every Bite: Honestly, the flavor combo is chef’s kiss—that citrusy, fizzy kick from the soda cuts through the buttery crust like a dream. The eggs make it rich but light, so it’s not too heavy after a long day. (Yes, even on a Tuesday night.)
- Party or Pantry: Between us, this pie works for everything. Serve it at a BBQ when you need a sweet finish, or pull it out for a lazy Sunday when you’re craving something familiar. The leftovers? They disappear just as fast as the first slice—no one will guess it’s basically dessert made with pantry staples.
Step-by-step instructions for Mountain Dew pie
Here's how to create that iconic citrusy filling and buttery crumb topping—every layer matters.
👨🍳 Step 1: Prepare the Crust and Crumb Topping
First, make the pie crust by cutting the 1 sheet salted butter into small cubes and mixing with the 2.5 cups all-purpose flour and 1 tablespoon extra flour until crumbly. Add the 0.5 cup ice water gradually, mixing just until the dough comes together. Shape into a disk, wrap in plastic, and chill for 30 minutes while you prepare the filling.
For the crumb topping, pulse the 0.75 cup unsalted butter (cold and cubed), 0.5 cup light brown sugar, 0.5 cup old-fashioned rolled oats, and 0.25 cup chopped pecans in a food processor until coarse crumbs form. Set aside—this will add the signature crunch to every bite.
🍳 Step 2: Whisk the Mountain Dew Filling
In a large bowl, whisk together the 1.5 cups Mountain Dew Soda (chilled), 1.5 cups granulated sugar, 4 whole large eggs, 0.5 cup all-purpose flour, 2 tablespoons cornstarch, 1 teaspoon vanilla extract, and 1 tablespoon lemon juice until smooth and fully combined. The mixture should be thick but pourable—this ensures a perfect set without being too dense.
Here's the thing—don't overmix. You want a few small bubbles, but the batter should be uniform. The Mountain Dew's natural acidity helps balance the sweetness, so resist the urge to add more sugar. Taste the mixture now—it should be sweet, tangy, and slightly fizzy.
🥘 Step 3: Assemble and Bake the Pie
Roll out the chilled pie crust and fit it into a 9-inch pie dish, pressing gently to form the sides. Pour the Mountain Dew filling into the crust, spreading it evenly. The filling will bubble slightly as it bakes, so don't fill it completely to the top—leave about ½ inch of headspace.
Sprinkle the crumb topping evenly over the filling, pressing down lightly with your fingertips. Bake at 375°F for 50-55 minutes until the filling is set but still slightly jiggly in the center (it'll firm up as it cools). The crust should be golden brown, and the crumb topping should look toasted and crisp.
⏰ Step 4: Cool and Serve
Remove the pie from the oven and let it cool completely on a wire rack for at least 2 hours. This cooling step is crucial—the filling needs time to fully set and develop its signature texture. If you can't wait, chill it in the refrigerator for 1 hour to speed up the process.
Once cooled, whip the 0.5 cup heavy whipping cream until soft peaks form and dollop it on top of each slice. The contrast of creamy, cool topping against the warm, citrusy filling is what makes this pie unforgettable. Serve slices with a scoop of vanilla ice cream for the full nostalgic experience.
Pro Tips For Making Mountain Dew Pie
- Reduce the Soda First: Simmer the Mountain Dew in a saucepan over medium-high heat until it reduces to about 1/3 of its original volume—this thickens the filling and prevents a runny pie. I learned this the hard way after a pie oozed out the sides like a soda fountain disaster.
- Whisk Eggs Like a Pro: Beat the eggs and sugar together until the mixture is pale yellow and ribbony—drop a spoonful back into the bowl and it should streak slowly. Overmixing turns the filling gummy; under-mixing leaves it flat. (Yes, even if you're impatient like me.)
- Chill the Filling: Let the Mountain Dew custard sit in the fridge for at least 2 hours before baking—this helps the eggs fully thicken and cuts down on cracking. I skipped this once and ended up with a pie that looked like a lava lamp.
- Use Cold Butter in Crust: Cut the unsalted butter into the flour mixture until the texture resembles coarse crumbs with pea-sized butter pieces—this ensures flaky layers, not a dense brick. I was skeptical until I tried it; now I never skip it.
Serving suggestions for leftovers
Classic Whipped Cream
No Mountain Dew pie is complete without a dollop of homemade whipped cream—light, fluffy, and slightly sweet. Whip ½ cup heavy whipping cream with 1 tablespoon powdered sugar and ½ teaspoon vanilla extract until soft peaks form.
I use a hand mixer for 2-3 minutes, then chill the bowl in the freezer for 5 minutes before whipping to get the best texture. Spoon it generously over each slice for that creamy contrast. 🥛
Caramel Drizzle
For an extra touch of indulgence, drizzle homemade caramel sauce over the pie slices. My go-to recipe uses 1 cup granulated sugar, ½ cup heavy cream, and 4 tablespoons unsalted butter, simmered until golden.
Let it cool slightly before drizzling—just 1-2 teaspoons per slice adds a rich, buttery finish. Store-bought caramel works in a pinch, but homemade tastes like a million bucks. 🍯
Vanilla Ice Cream
Serve your Mountain Dew pie with a scoop of vanilla ice cream for the ultimate nostalgic combo. I recommend Breyers Vanilla or Ben & Jerry’s Phish Food for that creamy, dreamy texture.
The cold ice cream cuts through the tangy filling, balancing the sweetness. For a fun twist, let guests mix their pie slice with a scoop of ice cream in a bowl. 🍦
Citrus Zest Garnish
Brighten up your pie with a sprinkle of lemon or lime zest before serving. The citrusy aroma complements the Mountain Dew flavor beautifully. Use a microplane to grate ½ teaspoon zest per slice—just enough to add a pop of color and a hint of freshness.
Avoid too much, or it’ll overpower the pie’s signature taste. 🍋
Cinnamon Sugar Crumble
For a warm, spiced twist, sprinkle a pinch of cinnamon sugar over the whipped cream. Mix 1 tablespoon granulated sugar with ½ teaspoon ground cinnamon and dust lightly on top.
The warmth of the cinnamon pairs perfectly with the citrusy filling, adding depth to every bite. This works especially well if you’re serving the pie warm. 🌟
Warm vs. Cold Serving
This pie tastes amazing both warm and cold, but the texture changes dramatically. Serve it chilled (after at least 4 hours in the fridge) for a creamy, set filling with a crisp crumb topping.
For a warm version, bake at 350°F for 5-7 minutes before serving—just enough to melt the whipped cream slightly. I love offering both options at parties so guests can choose their preference. ⏰

Frequently asked questions
Can I substitute Mountain Dew with another soda?
While nothing perfectly replaces Mountain Dew, Fanta Orange or a mix of Sprite and lemon-lime soda works in a pinch. The citrus notes are key—avoid colas or root beer, as they’ll alter the tangy-sweet balance. For best results, use 1.5 cups of the substitute and add ½ teaspoon extra lemon juice to mimic the acidity.
Why does my pie filling look watery after baking?
Underbaking is the most common cause. The filling should be slightly jiggly in the center when done—it firms up as it cools. If yours is still runny, bake 5-10 minutes longer at 350°F. For extra insurance, whisk 1 extra tablespoon cornstarch into the filling before baking.
How do I make the crumb topping extra crispy?
Toast the oats and pecans in a dry skillet for 2-3 minutes before mixing with butter and sugar—this adds depth of flavor and crunch. For extra crispiness, press the topping firmly onto the filling before baking, and bake 2-3 minutes longer at the end of the baking time. A quick broil for 30 seconds (watch closely!) gives a golden finish.
Can I make this pie ahead of time?
Assemble the pie (without baking) and refrigerate for up to 24 hours. Bake it straight from the fridge—just add 5-10 minutes to the baking time. For leftovers, store slices covered at room temperature for 2 days or refrigerate for 4 days. To revive stale crumb topping, warm slices at 350°F for 5 minutes before serving.
What’s the secret to a flaky pie crust?
Keep the butter cold and cut it into small cubes—this ensures steam pockets for flakiness. Use ice water (not cold) and mix just until the dough forms. Chill the dough for 30 minutes before rolling, and avoid overworking it. For extra insurance, blind-bake the crust for 5 minutes at 375°F before adding filling.
