Ingredients
Method
Prep
- Preheat oven to 325–350°F (165–175°C).
- Grease and flour a 9-inch Bundt pan.
Make batter
- Cream butter and sugar until light and fluffy (3–4 minutes).
- Add eggs one at a time, mixing well after each.
- Beat in vanilla.
- Whisk flour, baking powder, and salt in a separate bowl.
- Add dry ingredients to the batter in three additions, alternating with milk (start and end with dry). Mix until just combined.
Color the batter
- Divide batter into three equal bowls: white (uncolored), red, and blue.
- Add a small amount of red gel coloring to the red bowl and blue gel coloring to the blue bowl. Stir until vibrant; add more as needed.
Layer and swirl in the pan
- Spoon dollops of red, white, and blue batter into the prepared pan in a repeating pattern around the ring.
- Lightly swirl with a skewer or knife to create a marbled patriotic effect, but don’t overmix.
- Repeat with the remaining batter until the pan is about 2/3 full.
Bake
- Bake 55–70 minutes, or until a toothpick inserted near the center comes out clean or with a few crumbs.
Cool and glaze (optional)
- Let cake cool in the pan about 20 minutes, then invert onto a rack to cool completely.
- For glaze: whisk 1 cup powdered sugar with 2–3 tbsp milk or water
- If using dairy-free glaze, use dairy-free milk and dairy-free chocolate (if desired) and proceed with glaze.
Notes
- Gel colors yield the brightest red and blue.
- If you don’t have a Bundt pan, bake as two 8-inch rounds or a sheet cake and create marbling by stacking/frosting.
