Our dogs deserve all the love in the world—so why not spoil them on their birthday with a delicious homemade birthday cake? With this peanut butter and banana cake, you're only five easy steps away from a birthday your pup is sure to remember. Simply mix the ingredients together, throw the pans in the oven, prepare the mashed potato frosting, and then the fun part—decorations. There are many ways you can decorate your pup's special cake, so be creative and maybe even personalize it. As an optional step—but one your dog is sure to appreciate—sprinkle some crumbled bacon bits on top for some extra flavor and garnish.

Ingredients

  • 1 large ripe banana
  • 2 eggs
  • 3 tablespoons natural creamy peanut butter*
  • 2 tablespoons plus 1 tsp. honey
  • 1 cup whole wheat flour
  • ⅓ water
  • 2 tablespoons olive oil
  • 1 ½ teaspoons baking powder
  • 1 6-ounce Russet potato, peeled and cut into 1-inch cubes
  • 3 tablespoons plain yogurt*
  • Crisp-cooked and cooled bacon, crumbled (optional)**

Directions

Step OnePreheat oven to 350°F. Lightly coat two 6-inch round baking pans with nonstick spray and line the bottoms with parchment paper; set aside.

Step TwoIn a medium bowl, mash banana until smooth. Using an electric mixer, beat in eggs, peanut butter, and 2 Tbsp. honey on high speed until combined. Add flour, water, olive oil, and baking powder; beat until smooth. Divide batter between prepared pans.

Step ThreeBake 20 to 22 minutes until a toothpick inserted in the center comes out clean. Cool the dog birthday cakes in pans for 5 minutes. Remove layers from pans; cool completely on a wire rack.

Step FourMeanwhile, prepare frosting. Place potato pieces in a medium saucepan and cover with water. Bring to boiling over high heat. Reduce heat and simmer, covered, about 20 minutes until very tender. Drain and cool slightly; transfer to a medium mixing bowl. Add yogurt and remaining 1 tsp. honey. Beat with an electric mixer on medium speed for about 1 minute. Add water as needed to reach a smooth frosting consistency and then beat on high speed for an additional minute or until completely smooth and light.

Step FivePlace one cake layer on a platter. Top with a thin layer of frosting. Add remaining cake layer. Top with remaining frosting. If desired, sprinkle with crumbled bacon and add a dog-themed cake topper.

Storage: Lightly cover cake and store in the refrigerator for up to 3 days.
