Ingredients

  • 2 sticks (226g) unsalted butter, softened
  • 2 cups (400g) sugar
  • 4 large eggs, room temperature
  • 3 cups (342g) cake flour (see notes for substitution)
  • 3 teaspoons (12g) baking powder
  • ½ teaspoon (3g) salt
  • zest of two oranges (for us, this was about ¼ cup.)
  • ¼ cup (54g) vegetable oil (we use canola oil)
  • 1 cup (235g) Buttermilk
  • 4 Tablespoons (45g) Orange Jello Powder (Don't make the Jello. See notes if you prefer orange extract.)
  • A small amount of orange coloring gel (optional)

Simple Orange Glaze

  • 2 cups Confectioners Sugar, sifted (measure then sift)
  • 3 to 4 Tablespoons 45 to 60g milk, (You can substitute part of all of this with fresh juice from an orange.)
  • Pinch of salt Approximately ¼ teaspoon
  • Orange Extract- Optional. Start with ½ teaspoon and add additional until you reach desired amount of flavor.

Buttercream Decorations

  • 1 stick unsalted butter, softened
  • 2 cups confectioners sugar
  • ½ teaspoon salt
  • 2-3 tablespoons milk or orange juice (or combination of the two (start with less, then add a bit more as needed.)
  • ½ teaspoon orange extract (optional)

Instructions

For the Cake

  • Preheat the oven to 325℉. Grease and flour a bundt or tube pan. Our pan has a baking capacity of 12 cups. This recipe makes about 7.5 cups of batter.
  • In a medium bowl, whisk the cake flour, baking powder, orange jello powder, and salt for 30 seconds. Set aside.
  • In another bowl, add the vegetable oil, zest of two oranges, and buttermilk. Set aside.
  • In the bowl of your mixer, add the butter and mix at medium speed until smooth. Gradually add the sugar and mix for 3 to 5 minutes until lightened in color and fluffy.
  • With the mixer on medium speed, add the eggs one at a time, mixing after each until the yellow of the yolk has blended.
  • With the mixer on low speed, alternately add the flour mixture and the buttermilk mixture, beginning and ending with the dry ingredients. (That will be three additions of dry and two of liquid). After the last addition, add orange coloring gel if you are using any, and mix just until incorporated.
  • Pour or scoop the orange cake batter into the prepared bundt pan. There should be at least 1 ¼ inches from the top of the batter to the top edge of the bundt pan. (A popular rule of thumb is not to fill the pan more than ¾ full.)
  • Bake at 325 degrees for 50-55 minutes or until a toothpick inserted into the center comes out clean or with just a few crumbs attached. Let cool 10 minutes and turn out. Baking times may vary. (Check after 45 minutes to be safe.)

Simple Orange Glaze

  • Combine confectioners sugar, 3T milk, orange extract (or fresh orange juice), and a pinch of salt in a small bowl and stir until smooth. Start with 3 tablespoons milk (or juice) and increase little by little as needed to reach desired consistency. If not using right away, place plastic wrap or damp paper towel over bowl.
  • Drizzle over the cooled pound cake. (I spooned mine into a piping bag with the tip snipped away for more control.) If the glaze is too thin, add a bit more powdered sugar. If it is too thick, add a bit more juice or a touch of milk.

Decorating the Cake

  • We tinted about ¼ cup or so of our frosting green for leaves, and the rest we tinted orange (approx. ¾ cup.) Adjust amounts based on your design. We piped orange rosettes with a 1M piping tip, and leaves with a large leaf tip 366 (a smaller 352 tip is a good option also.)
  • Store the cake in an airtight container or cake dome at room temperature for 2-3 days (or longer in the refrigerator). If refrigerating the cake, it should be taken out at least 2 hours before serving for the softest texture.

Notes

Orange Extract: If you would rather use orange extract than orange jello powder, we recommend using 1 Tablespoon. 
 
Substitute for Buttermilk: No Buttermilk? Here is a substitution: Add 1 tablespoon lemon juice or vinegar to a measuring cup. To that, add milk to the 1 cup mark. Stir and allow to sit for a minute or two to thicken.
 
Substitution for Cake Flour: Using all purpose flour (plain in UK) to make Cake Flour: For each cup of flour in a recipe, remove 2 Tablespoons of flour and replace with 2 Tablespoons cornstarch (cornflour in the UK). This recipe has 3 cups of flour so you will measure out 3 cups of all purpose flour, remove 6 Tablespoons and replace with 6 Tablespoons cornstarch, whisk to blend.
 
Bundt Pan: Our bundt pan has a baking capacity of 12 cups and measures about 10 inches. If you are working with a smaller pan, it will take longer to bake. Be careful not to overfill. (General rule of thumb: don't fill pan past ⅔ full)
 
Freezing: This cake can be frozen. If working in advance, we like to tightly wrap our freshly baked cake in a layer of plastic wrap and foil while the cake is still a bit warm and pop in the freezer. The cake can be frozen for up to three months.
 
Thawing: Bundt cakes take longer to thaw than cake layers. It is best to move the frozen, wrapped cake to the refrigerator the night before, and then move to the kitchen counter the next morning (still wrapped) to continue thawing for a few hours. If you'd like, you can remove the foil after a condensation has formed.
