pro tips

• mise en place: prepare all of your ingredients and supplies before starting the bake.
• equipment varies: the best way to ensure that your oven is at the correct temperature is to get an oven thermometer. I use a lift stand mixer for the majority of my recipes but you can use a tilt-head mixer or a handheld mixer.
• room temperature ingredients: these mix better than cold. Warm egg whites get more volume.
• parchment paper: use the pan as a template to cut or fold the parchment to fit the pan. Lay the pan on top of the parchment paper and cut perpendicular slits at the corners. Fold the paper at the cuts into a perfect insert for the pan.

s’more blondies recipe instructions

graham cracker blondies

step one: Preheat oven to 345°F. Lightly grease an 8×8 square pan and fit with parchment paper.

step two: Combine the graham cracker crumbs, flour, baking soda, and salt in a bowl. Set aside.

step three: In the bowl of a stand mixer fitted with the paddle attachment, add the egg and brown sugar. Beat for 3 minutes until combined. Add the cubed butter and continue to mix until combined. The butter will look chunky, that’s ok, it will smooth out with further mixing. Add the sweetened condensed milk and vanilla extract. Beat for 10 minutes on medium speed until light and fluffy. Be patient, it will take some time.

step four: Add the dry ingredients and mix on first speed until just combined. Pour into the prepared pan and smooth out. Bake for 18 minutes. The center will be slightly jiggly but set and the outer edges will be golden brown. Allow to cool to room temperature.

dark chocolate ganache

step one: Using a double boiler, combine the chocolate and sweetened condensed milk until melted and smooth. Pour over the cool blondies. Let set in the refrigerator while you make the meringue.

vanilla bean marshmallow fluff (aka vanilla bean swiss meringue)

step one: Add the egg whites and sugar to the bowl of a stand mixer. Place atop a double boiler and whisk continuously until the mixture reaches 160°F.

step two: Attach the bowl to the stand mixer with the whisk attachment and whisk on medium speed for 3 minutes. Add the vanilla bean paste and pinch of salt then continue to whisk on high speed for 10 minutes until stiff peaks.

step three: Spread the fluff on top of the ganache. Make a swirl pattern with your offset spatula or you could add the fluff to a piping bag with a star tip and pipe dollops all over. Using a kitchen torch, toast the meringue to a nice golden brown. (or darker, if you’re like me and like slightly burnt marshmallows).
