Why You'll Love This Recipe
- Gooey Marshmallows: Everyone loves S’More Bars because of the combination of graham crackers, chocolate and gooey marshmallows! These Valentine’s Day S’more Bars use my favorite organic marshmallow crème for that perfectly gooey mallow that you all love!
- Naturally Colored: I use Unreal Milk Chocolate Gems that are naturally colored. I did have to pick out the pink and purples, as the bag also includes blue and greens. If you made Easy Christmas Present Brownies (like I did), then you'll have extra pink and purples in the bag!
- Easy: This recipe for Valentine’s Day S’More Bars is incredibly easy! For how delicious these are, they require minimal effort, which is my favorite kind of dessert to make!
- Eggless: These are naturally eggless s'more bars! So, if you have someone that has an egg allergy, this is a great recipe to make for them!
Ingredients

- Light Brown Sugar: I'm using my homemade light brown sugar, but store bought also works.
- Heavy Whipping Cream: This makes these dessert bars incredibly moist, soft, and chewy. It also replaces eggs, so these bars can be gooey without worry of underbaking with eggs.
- All Purpose Flour: I use Cairnspring Mills, this is my favorite!
- Baking Soda: I use baking soda because there is brown sugar in this recipe. Read my post on the Difference Between Baking Soda and Baking Powder for more info on leavening agents.
- Marshmallow Creme: I'm using Toonie Moonie Organic Marshmallow Creme, which is the only organic marshmallow “fluff” on the market. It's so good and perfect for this!
- Chocolate Candies: I'm using Unreal Milk Chocolate Gems and I picked out the purple and pinks. These are natural candies, non GMO, and use plant based dyes. They are basically the best kind of M&M's out there!

Baker's Tips for Valentine's Day S'More Bars
- Always weigh ingredients for the best results.
- Make sure your butter is soft. I like to leave butter out on the counter overnight to soften naturally. If you have to microwave it, then be sure to do only 10 second intervals per half cup. This will prevent it from melting in specific spots.
- I use light brown sugar here. If you don’t have it, you can easily make your own with my Homemade Light Brown Sugar. If you don’t have molasses, you can use half cane sugar and half dark brown sugar as well (that’s basically the same thing!).
- I use Toonie Moonie Marshmallow Crème for this recipe as it’s the only organic marshmallow fluff out there! If you are not concerned with organic, you are welcome to use any marshmallow fluff or even mini marshmallows.
- I use Unreal Milk Chocolate Gems and I picked out the pinks and purples. This is the only naturally colored chocolate candy I could find! This would be a fun activity for kids, have them pick out the pinks and purples, let them eat some of the greens and blues in the process! If you are not concerned about artificial colors, you can use any kind of chocolate candy you like.
- These may look a little jiggly when they come out of the oven, that’s okay, they will set up!
- Make sure to store these in an airtight container so they stay soft and chewy.
How to Make Valentine's Day S'More Bars

- Preheat the oven to 325°F. Line an 8×8-inch baking pan with parchment paper. In the bowl of a stand mixer fitted with the paddle attachment, add the butter, light brown sugar, and vanilla extract. Mix on low until combined and there are no chunks of butter.

- Add the heavy whipping cream, flour, baking soda, and sea salt.

- Mix together until a stiff cookie dough forms.

- Place three-quarters of the dough (just eyeball it) into the baking pan and press it with your hands or a spatula to form an even layer.

- Top the cookie dough with the marshmallow crème and spread evenly.

- Break the graham crackers into pieces and sprinkle the candies and graham crackers on top of the marshmallow.

- Add the pink and purple candies on top of the graham crackers.

- Add the remaining cookie dough mixture on top by breaking it into little chunks and adding evenly on top of the bars, allowing parts of marshmallow crème, candies, and graham crackers to show through.

- Bake for 30 to 35 minutes or until the cookie portion looks lightly browned and it’s only a little jiggly. Allow to cool completely in the pan.

- Cut the bars into 9 bars. Store in an airtight container for up to 5 days.
