Heat your oven to 350°F. Coat a loaf or bundt pan with butter and dust with flour. Beat the soft butter and white sugar together in a big bowl till they're fluffy. Mix in eggs one by one, making sure each one's fully mixed before adding another. Stir in the vanilla.

Mix flour, baking powder, and salt in another bowl. Add this dry mix to your butter mixture bit by bit, alternating with splashes of milk. Don't overmix – just blend till everything's combined.

Carefully fold your chopped peaches and cinnamon into the cake mix. Make sure they're spread out evenly so the cake stays light and fluffy.

Mix your dark sugar, melted butter, and flour in a small bowl until it's crumbly. Scatter this mix over the top of your batter to create a sweet crust when baked.

Pour your batter with the topping into your pan. Bake for about 50-60 minutes. Check it's done by sticking a toothpick in the middle – it should come out clean. Let it cool completely before moving on.

In a fresh bowl, whip together your soft butter, marshmallow cream, sugar, and vanilla until it's smooth and light.

After the cake's cooled down, take a piping bag and push the cream filling into the cake from underneath or from the sides, just like a Twinkie.
