Halloween Jalapeño Popper Mummies are savory, oven-baked appetizers made with fresh jalapeño halves stuffed with a creamy cheddar cheese filling and wrapped in strips of golden crescent roll dough. Small black olive eyes give each popper its mummy appearance. The contrast between flaky pastry, melted cheese, and tender peppers makes these a flavorful Halloween party appetizer with a mild-to-moderate kick of heat.
The key is controlling moisture and allowing the pastry to brown properly. Removing the jalapeño seeds and membranes reduces much of the pepper's heat, while softened cream cheese binds the shredded cheddar into a thick filling. Baking at 375°F (190°C) allows the crescent dough to puff and turn golden as the peppers soften. Leaving small gaps between the dough strips gives steam room to escape and keeps the mummy bandages clearly defined.
Why This Recipe Works
- Balanced, creamy filling: Softened cream cheese provides a smooth base that holds the shredded cheddar and scallions together. As the cheese heats, the filling softens without becoming as runny as shredded cheese alone.
- Better heat and moisture control: Removing the seeds and pale inner membranes reduces the concentration of spicy capsaicin-bearing tissue. Keeping the filling inside the pepper halves helps contain the cheese as the peppers release moisture during baking.
- Golden, defined mummy bandages: Refrigerated crescent roll dough contains fat that helps create a tender, layered texture. Exposed strips brown in the oven through the Maillard reaction, while small gaps allow moisture to escape and preserve the wrapped appearance.

Ingredients List
For the Jalapeño Poppers
- 6 medium fresh jalapeño peppers (approximately 6 oz / 170 g total), washed, dried, and halved lengthwise
- 4 oz (113 g) full-fat cream cheese, softened
- 1/2 cup (57 g) sharp cheddar cheese, freshly shredded
- 1 medium scallion (approximately 0.5 oz / 15 g), finely chopped
- 1/4 teaspoon (0.8 g) garlic powder
For the Mummy Wrapping
- 1 can (8 oz / 227 g) refrigerated crescent roll dough, kept chilled until ready to use
For the Mummy Eyes
- 6 medium pitted black olives (approximately 0.7 oz / 20 g), each cut into 4 small pieces to make 24 eyes
Ingredient Notes and Substitutions
- Jalapeño Peppers: Fresh jalapeños provide the structure for the filling and develop a softer texture during baking as their moisture evaporates. Choose firm, similarly sized peppers for more even cooking. Substitution: Use mini sweet peppers for a milder appetizer; their thinner walls and higher natural sweetness produce a less spicy result.
- Cream Cheese: Full-fat cream cheese binds the shredded cheddar and helps the filling remain creamy as it heats. Softening it before mixing prevents lumps and makes the filling easier to spread. Substitution: Use softened Neufchâtel cheese for a lighter filling, although its higher moisture content can make the mixture slightly softer.
- Refrigerated Crescent Roll Dough: Crescent dough forms the mummy bandages and develops a lightly crisp, golden exterior as its fat and moisture react to oven heat. Keeping it chilled reduces sticking and helps the strips retain their shape. Substitution: Use refrigerated puff pastry cut into narrow strips; the result will be more layered and flaky, and the baking time may require adjustment.
Step-by-Step Instructions
Step 1: Preheat the Oven.
Preheat the oven to 375°F (190°C) for approximately 10 minutes while preparing the ingredients. Line an 18 x 13-inch (46 x 33 cm) rimmed baking sheet with parchment paper. The oven should be fully heated before the wrapped peppers go in so the dough begins puffing as soon as it meets the hot air.
Step 2: Prepare the Jalapeño Halves.
Place the 6 washed and dried jalapeño peppers on a cutting board. Use the 12 lengthwise halves specified in the ingredient list, keeping the outer walls intact. With a small spoon, scrape out the seeds and pale membranes. Pat the cut surfaces dry with paper towels; removing excess moisture helps the cheese filling stay in place rather than sliding across the peppers.
Step 3: Mix the Cheese Filling.
Add 4 oz (113 g) softened cream cheese, 1/2 cup (57 g) freshly shredded sharp cheddar cheese, 1 finely chopped medium scallion (approximately 0.5 oz / 15 g), and 1/4 teaspoon (0.8 g) garlic powder to a medium bowl. Stir for approximately 2 minutes, until the mixture is thick, evenly blended, and free of large cream cheese lumps. The filling should hold its shape on a spoon.
Step 4: Fill the Jalapeños.
Divide the cheese mixture evenly among the 12 prepared jalapeño halves. Press the mixture gently into each cavity and smooth the surface without piling it excessively above the pepper edges. A compact filling is less likely to spill as it heats. Arrange the stuffed halves cut side up on the prepared baking sheet.
Step 5: Cut the Crescent Dough.
Unroll 1 can (8 oz / 227 g) refrigerated crescent roll dough onto the clean cutting board. If the dough has perforations, press them together to form a continuous sheet. Using a pizza cutter or sharp knife, slice the dough into strips approximately 1/4 inch (6 mm) wide. Work while the dough is cold so the strips remain flexible without stretching excessively or sticking together.
Step 6: Wrap the Mummy Bandages.
Wrap approximately 2 dough strips around each stuffed jalapeño half, crossing them at slight angles to resemble mummy bandages. Keep the filling facing upward and leave a small uncovered space near the wider end for the eyes. Tuck the strip ends underneath each pepper to help secure them. Return the wrapped jalapeños to the lined baking sheet with visible space between each one so hot air can circulate.
Step 7: Bake Until Golden.
Place the baking sheet on the center oven rack and bake at 375°F (190°C) for approximately 15 minutes. The mummies are ready when the crescent dough is puffed, golden brown, and no longer raw-looking along the edges, the cheddar filling is melted, and the jalapeño walls have softened slightly. If the dough is still pale, continue baking until the visual doneness cues are reached.
Step 8: Add the Eyes and Serve.
Remove the baking sheet from the oven and allow the mummies to cool for 5 minutes so the filling begins to set and the pastry firms up. Use the 24 prepared black olive pieces from the 6 medium pitted black olives (approximately 0.7 oz / 20 g). Press 2 olive pieces into the exposed cheese on each mummy to create the eyes. Transfer carefully to a serving platter and serve warm, when the pastry is lightly crisp and the filling is creamy.
Storage, Freezing, and Make-Ahead Instructions
- Refrigerator: Allow the baked jalapeño popper mummies to cool, then transfer them to an airtight container and refrigerate within 2 hours of baking. Store at 40°F (4°C) or below for up to 3 to 4 days. The pastry will gradually absorb moisture from the filling, so refrigerating the mummies in a single layer helps prevent them from sticking together.
- Freezer: The fully baked mummies can be frozen after cooling. Arrange them in a single layer until firm, then transfer to an airtight freezer-safe container with parchment between layers. For best quality, use within 1 to 2 months. Freezing can soften the peppers and change the cream cheese filling's texture as ice crystals form, so reheated mummies may be less crisp and creamy than freshly baked ones.
- Make-Ahead and Reheating: Prepare the cheese filling and hollow out the jalapeños up to 24 hours in advance, keeping them covered separately in the refrigerator. Assemble with chilled crescent dough shortly before baking to limit moisture absorption. Reheat refrigerated baked mummies in a 375°F (190°C) oven for approximately 8 to 10 minutes, or until the pastry is crisp and the center reaches 165°F (74°C). Reheat frozen mummies in the same oven after thawing overnight in the refrigerator, checking that the centers reach the same temperature.
FAQ
Can I make Halloween Jalapeño Popper Mummies ahead of time?
Yes. Prepare the filling and peppers up to 24 hours ahead, but wrap them shortly before baking so moisture from the filling does not soften the raw crescent dough.
How do I make jalapeño popper mummies less spicy?
Remove the seeds and all pale inner membranes, where much of the capsaicin-bearing tissue is concentrated. For a non-spicy version, substitute mini sweet peppers, which retain their shape during baking without the jalapeño heat.
Why is my crescent roll dough soggy?
Excess moisture from the peppers or filling, overly thick dough overlaps, and underbaking can leave the pastry soft. Dry the peppers thoroughly, keep the strips narrow, and bake until the exposed dough is uniformly golden.
Can I use puff pastry instead of crescent roll dough?
Yes. Puff pastry creates a lighter, more layered wrapping because steam expands between its butter-rich layers, but it may require a different baking time to become fully crisp.
