I exchanged the chocolate chips for a chocolate spread (because I have to get rid of it...) that is infused with blood orange flavour, thus supporting the slight orange flavour in the batter.
Thanks so much to Jennifer of Cooking for Comfort who opted for the great Nutty Chocolatey Swirly Sour Cream Bundt Cake! Go to her page to find the recipe, or have a look at Dorie's book (page 182).
P.S.: The February recipes are here! Hooray! This is going to be the last full month I bake along with the TWD-group until Easter Sunday, because I like to deny all sweets (and alcohol and meat) between Ash Wednesday and Easter Sunday. Nothing religious. Just the feeling, some weeks without these things would be no harm after all the Advent, christmas, New Year and birthday gourmandizing. Last year I made some other recipes from the book instead that go without sugar (biscuits, scones, some muffins). Therefore I am especially looking forward to Great Grains Muffins, Bourbon Bread Pudding and Chocolate Oatmeal Drops. (The Toasted Almond Scones were one of the recipes I pre-made last year during Lenten)
