- Begin by preheating your oven to 350 degrees Fahrenheit or 175 degrees Celsius Make sure your Bundt pan is thoroughly greased getting every ridge and corner to prevent sticking
- Mix Dry Ingredients:
- In a medium bowl combine the flour baking powder baking soda salt and first measure of cinnamon Use a whisk to combine and aerate for an extra fluffy crumb
- Cream Butter and Sugar:
- Use a large mixing bowl and beat the softened butter with the granulated sugar for about three to four minutes until the mixture is very light in color and airy Scrape the bowl and add the eggs one at a time fully blending each before the next Stir in the vanilla so the batter smells like a bakery
- Alternate Wet and Dry:
- Add about one third of the dry mix into the large bowl and mix gently Just as soon as it is blended pour in half the sour cream Repeat in this order ending with the flour mixture Mixing only until you see no more dry bits keeps the cake extra tender

- Bake to Perfection:
- Transfer the pan to the middle rack of your oven and bake for forty five to fifty five minutes The cake is ready when a toothpick inserted into the highest part comes out clean or with just a few moist crumbs Let it rest for ten minutes in the pan then carefully invert onto a wire rack to finish cooling
- Serve with Love:
- Once the cake is fully cool dust with powdered sugar for that bakery finish Slice and serve to delighted guests or family

My favorite part is the swirl of brown sugar and cinnamon inside It always reminds me of sneaking a pinch of cinnamon toast straight from the kitchen counter My niece once called it the happy surprise in every piece and now we say that every time we serve it
