Twix Pie Recipe: Oat Crown Crunch Over Caramel-Covered Swirls

This Twix pie recipe delivers the perfect balance of crunchy oat crowns and gooey caramel-covered swirls that taste just like the candy bar itself. The secret lies in layering melted chocolate and caramelized Twix bars between flaky pie crusts, creating a dessert that's rich, decadent, and impossible to resist.

I've perfected this recipe after years of testing—every slice delivers that signature Twix flavor in every bite.

The process starts with a classic pie crust that bakes up golden and flaky, providing the perfect foundation for the Twix filling. You'll melt chocolate and caramelize the Twix bars together, creating a luscious, swirled filling that stays gooey in the center while developing a slightly crispy edge.

The oat crown layer adds that signature crunch that makes this pie uniquely addictive.

What you'll end up with is a pie that looks stunning when sliced—layers of golden crust, caramelized Twix swirls, and those signature oat crowns peeking through. The aroma alone will have everyone gathering around your table, and the first bite delivers that perfect combination of chocolate, caramel, and cookie crunch.

This is the kind of dessert that feels like a professional bakery creation.

Serve warm with a scoop of vanilla ice cream or a dollop of whipped cream for the full experience. The recipe scales beautifully, so you can easily make it for parties or special occasions. Let's get started on creating this showstopping dessert!

Ingredients for twix pie

Twelve candy bars, one cup of oat crowns, and a flaky crust—this pie is pure indulgence.

Twix bars are the star, so grab the original flavor—no peanut butter versions here. I always buy mine in bulk from Costco when they're on sale, but any grocery store stock works. For the chocolate, Ghirardelli or Guittard chips melt beautifully. The oat crowns? Chop them yourself from the Twix bars—store-bought versions never taste the same. Keep your butter cold for that perfect flaky crust, and don't skip the ice water. This pie crust is foolproof once you get the technique down.

No Twix bars? Crushed Oreos mixed with caramel sauce can work in a pinch, but it won't be the same. Short on chocolate chips? Melt a chocolate bar instead—just make sure it's at least 60% cocoa for that rich flavor. The corn syrup is key for caramelizing the Twix filling, but if you're out, honey or maple syrup will do in a tight spot. For the crust, if you can't find all-purpose flour, cake flour works too—just add 1 tbsp back into the recipe. And trust me, the vanilla extract matters—imitation won't cut it here.

This pie tastes even better the next day, so make it ahead if you can. Store it at room temperature for 2-3 days or in the fridge for up to 5 days. To reheat, pop slices in the oven at 350°F for 5-10 minutes. I always make a double batch—leftovers disappear fast. Freeze individual slices for up to 2 months if you're planning ahead. Just let them thaw at room temperature before serving.

Step-by-step instructions for Twix pie recipe: oat crown crunch over caramel-covered swirls

Here's how to create a showstopping dessert with layers of gooey caramel, crispy oat crowns, and rich chocolate swirls.

In a large bowl, combine the 2.5 cups all-purpose flour, 0.5 cup granulated sugar, and 0.5 teaspoon salt. Cut in the 1 cup unsalted butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs with pea-sized butter pieces. This texture is crucial for creating flaky layers.

Gradually add the 0.5 cup ice water, one tablespoon at a time, mixing gently with a fork until the dough just comes together. The dough should hold when pressed but not be sticky. Form into a disk, wrap in plastic, and chill for at least 1 hour (or up to 2 days). This resting time prevents shrinking during baking.

Preheat your oven to 375°F. On a lightly floured surface, roll the chilled dough into a 12-inch circle (about 1/8-inch thick). Transfer to a 9-inch pie dish, trimming any excess dough. Prick the bottom with a fork and line with parchment paper.

Fill with pie weights or dried beans, then bake for 15 minutes. Remove the weights and bake for another 10 minutes until the edges are light golden brown and the crust is set. This pre-baking prevents a soggy bottom when you add the filling later.

In a medium saucepan, combine the 0.25 cup light corn syrup, 1 cup heavy cream, and 1 teaspoon vanilla extract. Bring to a gentle simmer over medium heat, stirring constantly until the mixture thickens slightly (about 5 minutes). Remove from heat and stir in the 1 cup oat crowns until fully coated.

Pour this mixture into the pre-baked crust, spreading it evenly. Sprinkle the remaining 1 tablespoon granulated sugar over the top for extra caramelization. Return to the oven and bake for 12-15 minutes until the filling is bubbly and golden. Let cool completely before adding the next layer.

In a microwave-safe bowl, melt the 1.5 cups dark chocolate chips in 30-second intervals, stirring between each, until completely smooth. Stir in the 1 whole large egg until fully incorporated. The mixture should be thick but pourable.

Pour the chocolate mixture over the cooled caramel-oat layer, spreading it evenly with a spatula. Use the back of the spatula to create gentle swirls in the chocolate for that classic pie look. Immediately place the 12 whole Twix candy bars on top, pressing them lightly into the chocolate to secure.

Refrigerate the pie for at least 4 hours (or overnight) to allow the chocolate to set completely. This chilling time is essential for clean slices and proper texture. When ready to serve, run a knife around the edges to loosen.

Slice into 8 equal wedges and serve at room temperature. The contrast of warm caramel, crisp oat crowns, and cool chocolate will have everyone begging for seconds. Store leftovers covered in the fridge for up to 3 days or freeze for longer storage.

Make-ahead tips for leftovers

Prep Ahead Timeline

Start your crust preparation the night before—rolling and chilling it for at least 1 hour (or up to 2 days) ensures perfect flakiness. I always make mine the evening before so it's ready to blind-bake first thing in the morning. This saves time and prevents last-minute stress. 📅

Filling Prep Shortcuts

Melt your chocolate and caramelize the oat crowns the same day you bake the crust. These components keep well in the fridge for 24 hours if stored in airtight containers.

I like to assemble the caramel-oat layer first, then refrigerate it until ready to add the chocolate swirls. This keeps everything organized and prevents messy cross-contamination.

Twix Bar Prep

Unwrap and chop your 12 Twix bars into oat crowns while the caramel-oat layer bakes. Store the chopped crowns in a small bowl at room temperature—they'll stay crunchy for up to 3 hours before the filling is complete.

For the whole bars, keep them unwrapped until you're ready to place them on top of the chocolate layer. This prevents them from softening prematurely.

Chilling Strategy

The 4-hour chilling time is non-negotiable for clean slices and proper texture. I often set a timer when I start baking so I remember to refrigerate promptly.

For parties, I'll make the pie completely the day before and store it covered at room temperature—it actually tastes better after the flavors meld overnight. Just bring it to room temperature for 30 minutes before serving.

Portioning for Parties

If serving a crowd, assemble the pie in a 9x13-inch baking dish instead of a pie plate—it's easier to slice and serves 12-16 people. I like to wrap individual slices in parchment paper and tie with twine for easy transport.

For the caramel-oat layer, double the recipe and divide it evenly between both dishes before adding the chocolate swirls. This keeps the texture consistent across both pies.

Freezing Individual Slices

For maximum convenience, slice the pie after chilling and wrap each portion tightly in plastic wrap. Place slices in a freezer bag with parchment paper between them to prevent sticking. They'll keep for up to 2 months.

To serve, thaw at room temperature for 1-2 hours—no reheating needed. The texture remains perfect, and the chocolate stays firm enough to hold its shape. 💫
