Creating the delicious Buckeye Bundt Cake is easy if you follow these simple steps:

1. Preheat your oven to 350°F (175°C). Grease and flour a Bundt pan.
2. Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, and salt.
3. Combine Wet Ingredients: In another bowl, whisk together the milk, vegetable oil, eggs, and vanilla extract until well blended.
4. Mix Together: Slowly add the wet ingredients to the dry ingredients, mixing until the batter is smooth and free of lumps.
5. Add Chocolate Chips: Fold in the semi-sweet chocolate chips if you desire extra chocolatey goodness.
6. Prepare Peanut Butter Filling: In a small bowl, mix the creamy peanut butter with powdered sugar until smooth and well combined.
7. Layer Batter: Pour half of the chocolate batter into the prepared Bundt pan. Spoon dollops of the peanut butter mixture over the batter, then cover with the remaining chocolate batter.
8. Bake the Cake: Place the cake in the preheated oven and bake for 50-60 minutes or until a toothpick inserted in the center comes out clean.
9. Cool the Cake: Remove the cake from the oven and allow it to cool in the pan for about 15-20 minutes. Then, invert the cake onto a wire rack to cool completely.
10. Prepare Icing: In a small saucepan, heat the heavy cream until just simmering. Remove from heat and add the semi-sweet chocolate chips, stirring until melted and smooth.
11. Drizzle Icing: Once the cake is completely cool, drizzle the chocolate icing over the top, letting it cascade down the sides.
