Preheat your oven to 350°F (175°C) and prepare a 9x5-inch loaf pan with non-stick spray to ensure easy release after baking.

Whisk together in a bowl the all-purpose flour, baking soda, baking powder, salt, ground cinnamon, ground allspice, and ground nutmeg until well combined, then set aside.

Combine in a separate bowl the granulated sugar, vegetable oil, and eggs, whisking until smooth and creamy. This mixture will bring moisture and sweetness to your loaf.

Stir in the apple butter and buttermilk until fully blended, allowing the flavors to meld together beautifully.

Fold the dry mixture into the wet ingredients gradually until just combined. Remember, over-mixing can result in a dense loaf, so gently bring it together.

Pour the batter into the prepared loaf pan and use a spatula to smooth the top, ensuring an even rise while baking.

Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean. The loaf should spring back when lightly pressed.

Cool the loaf in the pan for about 5-10 minutes, then transfer it to a wire rack to cool completely. This step is crucial for the best texture.

Cream softened butter and icing sugar in a bowl until crumbly, then beat in the cold cream cheese and apple butter until the frosting is smooth and creamy.

Frost the completely cooled loaf with the cream cheese frosting and swirl in extra apple butter decoratively for a lovely finish.
