Preheat oven to 375°F (190°C) and line a baking sheet with parchment paper.
Unroll crescent dough and cut each triangle into two smaller triangles.
In a medium bowl, mix cream cheese, bacon, jalapeños, garlic powder, onion powder, and cheddar cheese until well combined.
Place a teaspoon of the mixture onto each dough triangle and fold the edges to enclose.
Brush tops with egg wash for golden color.
Bake for 10–12 minutes or until golden brown and cooked through.
Let cool slightly and serve warm.
