- 1 teaspoon baking soda
- 1 teaspoon vanilla extract
- 2 cups sugar
- 2 cups all-purpose flour
- 1/4 teaspoon salt
- 1 cup butter (for frosting)

- 1/3 cup buttermilk (for frosting)
- 1 (16-ounce) package confectioners’ sugar
- 1 teaspoon vanilla extract (for frosting)

Instructions
- Step 1: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan thoroughly.
- Step 2: In a small saucepan over low heat, combine 1 cup butter, 1/3 cup cocoa, and 1 cup water. Stir constantly until the butter has melted completely. Remove the pan from heat.
- Step 3: Using an electric mixer, beat together the buttermilk, eggs, baking soda, and 1 teaspoon vanilla extract until the mixture is smooth and well combined.
- Step 4: Gradually pour in the melted butter mixture, continuing to beat until everything is well incorporated.
- Step 5: In a separate medium bowl, mix together the sugar, flour, and salt. Slowly add this dry mixture to the wet ingredients, beating until just blended.

- Step 8: Remove the saucepan from heat and stir in the confectioners’ sugar, remaining vanilla extract, and toasted pecans until fully combined.
- Step 9: Pour the warm frosting evenly over the warm cake. Allow the frosting to cool and set before cutting and serving.
Tips & Variations
- For extra moistness, be careful not to overbake the cake; check it a few minutes before the suggested time.
- Swap toasted pecans for walnuts or omit nuts altogether for a nut-free version.
- Add a teaspoon of espresso powder to the batter to deepen the chocolate flavor.
- Ensure the frosting is poured while still warm so it spreads smoothly and sets with a glossy finish.
Storage
Store the cake covered at room temperature for up to 2 days or in the refrigerator for up to 5 days. If refrigerated, let it come to room temperature before serving for the best texture. The cake can also be frozen without frosting for up to 3 months; thaw completely before frosting.

FAQs
Can I use regular milk instead of buttermilk?
Buttermilk provides acidity which reacts with baking soda to create a tender texture and slight tang. If you don’t have buttermilk, you can make a substitute by adding one tablespoon of lemon juice or vinegar to 1/2 cup of milk and letting it sit for 5 minutes.
How do I toast pecans properly?
To toast pecans, spread them in a single layer on a baking sheet and bake at 350°F (175°C) for about 5-7 minutes, stirring halfway through. Watch carefully to prevent burning and remove when they smell fragrant and are lightly browned.
