Ingredients

1 cup unsalted butter
2 cups granulated sugar
4 large eggs
1 teaspoon vanilla extract
1 cup all-purpose flour
1 cup unsweetened cocoa powder
1/2 teaspoon baking powder
1/4 teaspoon salt
2 cups mini marshmallows
1 cup chocolate ganache (made from chocolate and heavy cream)
1 cup chopped pecans

Directions

Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.
In a large bowl, cream together the butter and sugar until light and fluffy.
Add eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
In another bowl, whisk together the flour, cocoa powder, baking powder, and salt. Gradually add to the wet mixture until just combined.
Pour the batter into the prepared baking pan and bake for about 30-35 minutes, or until a toothpick inserted into the center comes out clean.
Once out of the oven, immediately sprinkle the mini marshmallows on top and return to the oven for an additional 5-7 minutes, until the marshmallows are puffy.
Remove from oven and let cool slightly. Spread the chocolate ganache over the marshmallows and sprinkle with chopped pecans.
Allow to cool completely before cutting into squares. Serve and enjoy!

Nutriments benefits

Mississippi Mud Cake is a dessert, so it mainly gives energy from sugar and fat. Here are a few points to keep in mind in plain language:

Calories and energy: The butter, sugar, and ganache make this cake high in calories. It is good for quick energy but eat in small portions.
Protein: Eggs add a little protein.
Minerals: Pecans add healthy fats, fiber, and small amounts of vitamins and minerals like magnesium and copper.
Cocoa benefits: Unsweetened cocoa powder has antioxidants that can be good for heart health in moderation.
Moderation: Because of the sugar and butter, enjoy this cake as an occasional treat.

What to Serve With Mississippi Mud Cake

A scoop of vanilla ice cream brightens the rich chocolate.
Fresh berries add a tart contrast and color.
A cup of black coffee or strong tea cuts the sweetness.
Whipped cream keeps the plate light and soft.
For a party, serve small squares on a tray with nuts or fruit on the side.

Try pairing it with another simple bar for variety, like carrot cake bars for guests who want something less chocolatey.

How to store Mississippi Mud Cake

Room temperature: Cover the cake with plastic wrap or a lid and keep at room temperature for 1–2 days.
Refrigerator: Store in an airtight container for up to 5 days. Let it sit at room temperature for 20–30 minutes before serving to soften the ganache.
Freezing: Wrap individual squares in plastic wrap and then foil. Freeze up to 2 months. Thaw in the fridge overnight and bring to room temperature before serving.

Tips and mistakes to avoid

Measure flour properly. Spoon the flour into your measuring cup and level it. Too much flour makes the cake dry.
Don’t overmix the batter after adding flour. Mix until just combined to keep the cake tender.
Watch the oven time. Ovens vary. Start checking at 30 minutes with a toothpick.
Add marshmallows at the right time. Put marshmallows on after the main bake and return to the oven only until puffy. If you leave them too long they can brown too much.
Warm the ganache slightly if it is too thick. A few seconds in the microwave will make it easy to spread.
Let the cake cool before cutting. Cutting warm squares can make a mess.
If you want a firmer top, chill the cake after adding ganache for 30–60 minutes before slicing.

For a different kind of sweet, you can try a twist on texture with a creamy dessert like churro cheesecake to compare textures and flavors.

Variation (if any)

Nut-free: Skip the pecans and sprinkle extra chocolate chips on top.
Extra gooey: Add 1/2 cup of sour cream or Greek yogurt to the batter for more moisture.
Dark chocolate: Use dark chocolate ganache for a deeper chocolate flavor.
Salted top: Sprinkle a light pinch of sea salt over the ganache to balance the sweetness.
Mini version: Bake in a muffin tin for portable, single-serve “mud cupcakes.”

FAQs

Q: Can I use large marshmallows instead of mini marshmallows?
A: Yes. Cut large marshmallows into smaller pieces so they melt evenly. Spread them across the top so all parts get covered.

Q: Can I make this gluten-free?
A: Yes. Use a 1:1 gluten-free flour blend and check that baking powder is gluten-free. The texture may be a little different.

Q: How do I make the ganache?
A: Heat heavy cream until hot (not boiling). Pour over chopped chocolate and let sit 1 minute. Stir until smooth. Cool slightly before spreading.

Q: Can I double the recipe?
A: Yes, use a larger pan or two pans. Baking time may change; check with a toothpick for doneness.

Q: Why did my marshmallows brown?
A: They browned because they were in the oven too long or your oven ran hot. Reduce the marshmallow time or lower the oven temp slightly.
