Ingredients

½ cup unsalted butter, melted

1 cup light brown sugar, packed

1 tbsp vanilla extract

½ tsp salt

½ tsp baking powder

1 cup all-purpose flour

1 flax egg (1 tbsp ground flaxseed + 3 tbsp water, mixed and rested 5 min)

½ cup vegan marshmallows (or mini regular marshmallows)

½ cup butterscotch chips (use dairy-free if needed)

Instructions

Preheat Oven:
Preheat to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it.

Make Wet Base:
In a mixing bowl, whisk melted butter and brown sugar until smooth and glossy.

Add Flax Egg & Flavorings:
Stir in vanilla, salt, and the prepared flax egg. Mix well.

Add Dry Ingredients:
Stir in flour and baking powder until just combined. Avoid overmixing.

Fold in Add-ins:
Gently fold in marshmallows and butterscotch chips.

Bake:
Spread the batter evenly into the pan. Bake for 22–25 minutes, or until top is golden and a toothpick comes out mostly clean.

Cool & Serve:
Let blondies cool completely in the pan before slicing into squares for best texture.

Notes

Vegan-Friendly: Use vegan butter and dairy-free chips to make it fully plant-based.

Storage: Store in an airtight container at room temperature for 3–4 days.

Texture Tip: Let cool fully to ensure clean cuts and chewy centers.
