Step 1

Preheat oven to 350. Grease a large bundt pan or mini bundt pans with floured baking spray (or regular spray and flour) and set aside.

Step 2

In the bowl of an electric mixer, beat together the oil, buttermilk, eggs, food coloring, vinegar and vanilla.

Step 3

In a separate bowl whisk together the flour, sugar, baking soda and cocoa powder.

Step 4

Add the dry ingredients to the mixer, in about four batches (so the batter doesn't form clumps).

Step 5

Pour the batter into the prepared pan. If using mini bundts, fill each one about three fourths full.

Step 6

Bake at 350 until a toothpick inserted into the center comes out clean. About 45 minutes for a full size bundt, or 18-20 minutes for a mini bundt.

Step 7

Remove from oven and set aside to cool completely before glazing.

Step 8

Combine all ingredients in a small bowl, stirring until smooth.

Step 9

Drizzle glaze over cooled bundt cakes.
