Step‑by‑Step Instructions for Ultimate Chocolatey S’mores Muffins
Step 1: Prepare the Graham Cracker Streusel
In a medium bowl, mix 3 tablespoons of melted unsalted butter with 3/4 cup of graham cracker crumbs and 1.5 tablespoons of sugar until the mixture resembles coarse crumbs. Once combined, cover the bowl and refrigerate the streusel mixture to allow it to firm up while you prepare the muffin batter.
Step 2: Preheat the Oven
Preheat your oven to 425°F (220°C) and line a 12-cup muffin tin with paper liners. This temperature will help create that beautiful rise for your Ultimate Chocolatey S’mores Muffins. While the oven heats, prepare your workspace and gather your ingredients for the muffin batter.
Step 3: Mix the Dry Ingredients
In a large mixing bowl, whisk together 2 cups of all-purpose flour, 1/3 cup of cocoa powder, 1/2 cup of sugar, 2 teaspoons of baking powder, 1/2 teaspoon of baking soda, and 1/2 teaspoon of kosher salt. Gently fold in 1/2 cup of chocolate chunks or chips, making sure they’re evenly distributed for that delightful chocolate burst in every muffin.
Step 4: Combine the Wet Ingredients
In another bowl, melt 3 tablespoons of butter with the remaining chocolate (if any) together until smooth. Stir in 1/2 cup of vegetable oil, 1/2 cup of whole milk, 1/2 cup of Greek yogurt, 2 large eggs, and 1 tablespoon of vanilla extract. Mix until well-blended and creamy, ensuring a luscious batter for your muffins.
Step 5: Mix Wet and Dry Ingredients
Gently pour the wet mixture into the bowl of dry ingredients. Using a spatula, fold the mixture until just combined—you want the batter to be slightly lumpy and not overmixed, which will keep your Ultimate Chocolatey S’mores Muffins perfectly fluffy.
Step 6: Fold in the Marshmallows
Carefully fold in 1 cup of mini marshmallows into your batter, ensuring they’re evenly distributed without breaking them down. This will create those beautiful gooey pockets of marshmallow in your muffins, enhancing the s’mores experience.
Step 7: Fill the Muffin Tins
Spoon the batter generously into the prepared muffin tin, filling each liner about three-quarters full to allow room for rising. Top each filled cup with extra chocolate chunks and marshmallows, and sprinkle your chilled graham cracker streusel mixture generously over the top for that crunchy finish.
Step 8: Bake the Muffins
Bake the muffins in the preheated oven for 7 minutes at 425°F, then reduce the temperature to 350°F (175°C) without opening the oven door. Continue baking for an additional 13 minutes, or until a toothpick inserted comes out clean, and the tops are beautifully domed and golden.
Step 9: Cool
Once baked, allow the muffins to cool in the tin for about 5 to 10 minutes, which will make for easier removal without breaking. After this, gently transfer them to a wire rack to cool completely, giving you that perfect, soft texture and aroma to enjoy.

Make Ahead Options
These Ultimate Chocolatey S’mores Muffins are perfect for meal prep enthusiasts! You can prepare the graham cracker streusel up to 24 hours in advance by mixing melted butter, graham cracker crumbs, and sugar, then refrigerating it. Additionally, you can mix the dry ingredients (flour, cocoa powder, sugar, baking powder, and baking soda) and store them in an airtight container for up to 3 days. When you’re ready to bake, simply combine the wet ingredients, fold in the marshmallows and chocolate, and distribute the batter into the muffin tin. The muffins will come out just as delicious, preserving that gooey, chocolatey goodness with minimal effort on busy days!
