In a bowl, whisk together the butter, oil and sugar. Add the eggs and buttermilk and combine until smooth.

Step 3

Pour in the flour, baking soda and salt and using a spatula, fold until combined.

Step 4

Grease a loaf pan, leaving a 1/2” border ungreased. Add 1/3 of the batter and sprinkle 1/3 of the cinnamon sugar.

Add another 1/3 of batter and 1/3 of cinnamon sugar. Repeat one last time, but before sprinkling the cinnamon sugar take a knife and swirl through the bread. Top with cinnamon sugar and bake for 55-60 minutes.

Allow to cool for 10 minutes and then remove from the pan to cool on a cooling rack.
