Next, add the eggs one at a time, mixing well after each addition, and then stir in the vanilla extract. In another bowl, whisk together the flour, cocoa powder, baking powder, and salt. Gradually add this dry mixture into the wet mixture, stirring until just combined. The batter will be thick and oh-so-deliciously chocolatey—you might be tempted to eat it raw, but I promise it’s even better baked!
Now, pour half of the batter into your prepared pan and spread it evenly. Bake this layer for about 20 minutes until it’s just set but not fully cooked. Take it out of the oven and immediately sprinkle the mini marshmallows over the warm cake. Then, pour the remaining batter on top, followed by the chopped pecans. Pop it back into the oven for another 25–30 minutes until a toothpick inserted comes out clean.
Once baked, let it cool completely. For the final touch, whisk together the powdered sugar, milk, and 1/2 teaspoon vanilla extract and drizzle it over the top of your cake. I like to rush this part to see how my cake turned out while trying to resist the sweet aroma wafting through the kitchen—it’s hard!
Pro Tips for Best Results
I tested this cake two ways—once with melted butter and once with softened butter. Honestly, the softened butter version made a big difference in texture. The cake was fluffier and rose beautifully! So go with the softened butter for the creaming process.
On my journey to perfect this cake, I learned that allowing the marshmallows to sit for a few minutes after taking the cake out of the oven helps them soften beautifully, resulting in that classic gooey texture. And don’t rush the cooling time; this cake tastes better the longer it sits (if you can resist it, that is!).
Lastly, I found that the quality of cocoa powder makes a noticeable difference in flavor. I usually opt for a Dutch-processed cocoa because it gives a deeper, richer chocolate taste. Trust me, your taste buds will thank you!
Common Mistakes to Avoid
One of the mistakes I made early on was not preheating the oven long enough. I thought a few minutes would suffice, but I found that my cake turned out unevenly baked, which is not ideal. Take those few extra moments to make sure your oven is at the right temperature before sliding in the cake; it’s crucial! See the next page below to continue…)
