How to Make S’mores Blondies
Preheat your oven: Set your oven to 350°F (175°C). Line an 8×8-inch square metal baking pan with parchment paper, allowing for a 2-inch overhang on each side. Use ¾-inch binder clips to secure the paper to the pan edges, providing a clean and easy lift-out later.
Mix the wet ingredients: In a large bowl, whisk together 1 large egg, ¾ cup (165g) packed light brown sugar, 1 tablespoon (15ml) honey, 1 teaspoon (5ml) pure vanilla extract, and ½ cup (113g) melted and cooled unsalted butter until the mixture is smooth and glossy.
Add dry ingredients: Stir in ½ teaspoon salt, ½ teaspoon ground cinnamon, ¼ teaspoon baking soda, and ¼ teaspoon baking powder, mixing until combined. Sift in 1 cup (142g) all-purpose flour and fold gently into the mixture until no streaks remain.
Incorporate chocolate and marshmallows: Gently fold in ⅔ cup (4oz/113g) dark chocolate chunks and 1 ⅓ cups (65g) mini marshmallows, making sure they are evenly distributed throughout the batter.
Prepare for baking: Layer the bottom of your prepared pan with 9 individual graham crackers, breaking them to fit as needed. Drop spoonfuls of the blondie batter over the graham crackers, spreading it evenly with a small offset spatula. Sprinkle extra chocolate chunks on top for added goodness.
Bake: Place the pan in the preheated oven and bake for 23-26 minutes. You’ll know they’re done when the top is golden, and the edges are slightly browned. Keep an eye out for a fragrant aroma wafting through the kitchen!
Cool and slice: Let the blondies cool in the pan for at least 30 minutes. Use the overhanging parchment to lift them out onto a cutting board. Slice them into squares either while still warm for that gooey s’mores experience or allow them to cool further for neat cuts. Greasing your knife with oil or butter helps make slicing easier and cleaner.
Storing & Reheating
Store your s’mores blondies at room temperature in an airtight container for up to 3 days. For longer storage, refrigerate them for up to a week or freeze the blondies wrapped tightly in plastic wrap for up to 3 months. When you’re ready to enjoy, simply reheat in the microwave for about 10-15 seconds to refresh their gooey texture, though be aware that the marshmallow filling may lose some fluffiness.
Chef’s Helpful Tips
- Don’t overmix: Mixing the batter too much can lead to dense blondies. Fold until just combined!
- Room temperature ingredients: Eggs and butter bring the best texture, so make sure to let them warm up a bit before starting.
- Check for doneness: A toothpick inserted should come out with a few moist crumbs, not completely clean.
- Add flair: Consider folding in nuts or using different types of chocolate chips for unique flavor combinations!
- Make-ahead: You can prepare the batter and refrigerate it overnight, then bake fresh the next day.
The delightful combination of sweet, chewy, and rich flavors in these blondies makes them an instant hit at any gathering. Plus, they’re easy to store and delicious in just about any form. Feel free to get creative with your mix-ins, and don’t be shy about trying new variations!
