2 tsp vanilla extract

👩🍳 Step-by-Step Instructions
1️⃣ Prepare the Pan
Preheat oven to 350°F (175°C).
Grease and flour a mini bundt pan (12 cups), tapping out excess flour.
2️⃣ Cream Butter & Sugar
Beat butter and sugar in a stand mixer (paddle attachment) until light and fluffy.
3️⃣ Add Eggs
Lightly whisk eggs, then add gradually while mixing on medium speed.
4️⃣ Add Sour Cream & Vanilla
Mix sour cream with vanilla, then beat into the batter for about 1 minute.
5️⃣ Add Dry Ingredients
Sift flour, baking powder, and salt.
Add to batter on low speed until just incorporated. Scrape bowl sides.
6️⃣ Create Chocolate Batter
Scoop out one-third of the batter.
Mix in melted chocolate and cocoa powder until smooth.
7️⃣ Pipe & Swirl
Transfer both batters into separate piping bags.
Pipe vanilla batter into molds, then chocolate batter in between.
Use a skewer to gently swirl for that classic marble effect.
8️⃣ Bake
Bake for 20 minutes, or until a skewer inserted comes out clean.
9️⃣ Cool & Glaze
Cool in pan for 30 minutes, then transfer to rack.
Dip or drizzle with rich chocolate ganache and let set.
🍫 Pro Tips
✨ Use room temperature ingredients for a smoother batter.
✨ Don’t over-swirl — less is more for defined marbling.
✨ For a large bundt pan, increase baking time to 45–55 minutes.
💛 Serving Suggestion
Serve slightly warm with coffee or tea for the ultimate cozy dessert moment.
