Peanut Butter Pumpkin Dog Birthday Cake

We made this cake for Chris' birthday and he and Clark loved it! The frosting is only made out of peanut butter, but is whipped to give it more of a frosting texture. Throw a dog party and let them all enjoy the cake, or freeze individual slices for future treats!

Ingredient Notes

• Canned Pumpkin: Use pumpkin puree, NOT pumpkin pie filling.
• Peanut Butter: Use a thick and creamy peanut butter, like Skippy or Jif.
• Coconut oil: Coconut oil is great for dogs (in moderation of course), as it makes their coats shiny!
• Eggs: You'll need two eggs for this recipe. 
• Oat Flour: You can make your own oat flour by grinding up rolled oats or quick cooking oats in a blender until it resembles flour. 
• Baking Soda: Baking soda gives this cake the perfect amount of rise.

Expert Baking Tips

• I used Skippy peanut butter, but I'm sure just about any thick and creamy peanut butter will work. 
• To make your own oat flour, simply grind up rolled oats or quick cooking oats in a blender until it resembles flour. 
• Whipping the peanut butter is completely optional for the frosting, but it fluffs it up a bit and makes it look more like frosting.
• Obviously your dog should not eat more than a slice of the cake at a time, so to store leftovers cut the cake up into individual slices, place in a zip lock bag, and freeze. 

All of the recipes on this blog are carefully developed with gram measurements so you can easily recreate them in your own kitchen with success. Volume measurements are extremely inaccurate and leave room for significant errors. Not all measuring cups are made equally, so your one cup of flour will be different from my one cup of flour. By providing precise measurements in grams (aside from minor ingredients, which are given in tsp/tbsp), you can make these recipes accurately and with less cleanup! All you need is this kitchen scale. 

If this still isn't enough to convince you, I have provided volume measurements in the recipe card. If you are interested in understanding the conversions, this is the best conversion chart.

But trust me, once you try baking in grams you'll never turn back!

Happy baking! x
