You can bake a pie that actually tastes like Mountain Dew Baja Midnight — dark berry gelatin filling with a citrus-lime zing in a buttery, crumbly crust. It's tangy, sweet, and electric blue in a way that shouldn't work but absolutely does. The weirdest pie you'll ever love.
Preheat oven to 350°F. Bake your prepared pie crust until golden and crisp, about 15 minutes. Let it cool fully so the filling stays layered and the crust stays Taco Bell-style crunchy.
In a saucepan, combine Mountain Dew Baja Midnight, blueberry filling, blackberry jam, lime zest, fresh lime juice, and granulated sugar. Bring to a simmer over medium heat, stirring frequently — you want the mixture bubbling but not boiling. This locks in the bold, citrus-berry flavor signature to Taco Bell’s Baja menu drops.
Once simmering, whisk in unflavored gelatin until fully dissolved, then add the blue food coloring for that electric, vivid Taco Bell experience visual. Stir over gentle heat for 2–3 minutes. Copycat tip: use gelatin for a jiggly, sliceable filling similar to Taco Bell’s test kitchen pies.
Remove the filling from heat and stir in unsalted butter, vanilla extract, and kosher salt. Butter gives richness and a crumbly finish; vanilla and salt balance the tang and sweetness.
Pour the filling into the cooled pie shell. Chill in the fridge for at least 2 hours until fully set. For crunch, serve cold — do not microwave or warm. Top with whipped cream and citrus zest if desired, but the main show is the layered, blue, tart center. Slice and enjoy Taco Bell’s boldest new pie flavor at home!
