Equipment

  • Small mixing bowl
  • Large mixing bowl
  • Measuring cups and spoons
  • Fork or potato masher
  • Blender or food processor, if making oat flour
  • On a silicone spatula or wooden spoon
  • Small round cake pan, about 4 to 6 inches
  • Parchment paper or nonstick cooking spray
  • Oven
  • Cooling rack

Ingredients
  

For the cake:

  • 1 cup rolled oats
  • 1 ripe banana mashed
  • 1 large egg
  • 1/2 cup fresh blueberries
  • 2 tablespoons natural peanut butter
  • 1/4 cup water

Optional topping:

  • 1/4 cup plain unsweetened Greek yogurt
  • 1 tablespoon natural peanut butter
  • A few extra blueberries for decoration
  • Important ingredient note
  • Always check your peanut butter label carefully before using it for a dog treat. Make sure it does not contain xylitol which is extremely dangerous for dogs.
  • Choose plain unsweetened peanut butter with simple ingredients whenever possible.
  • For the yogurt use plain and unsweetened yogurt without added sugar or artificial sweeteners.
  • How to Choose the Best Ingredients

Rolled Oats

  • Rolled oats are the foundation of this cake.
  • You can blend them into a fine flour using a blender or food processor. Homemade oat flour gives the cake a smoother texture and helps the ingredients hold together nicely.
  • If you prefer a slightly more rustic texture you can leave some of the oats less finely ground. Just remember that a finer oat flour generally creates a softer cake.
  • Choose plain oats without added flavorings or sweeteners.
  • Fresh or Frozen Blueberries
  • Fresh blueberries are wonderful in this recipe because they stay juicy and add bright little bursts of flavor.
  • Frozen blueberries can also work. If using frozen berries you can add them directly to the batter without thawing them first.
  • Smaller blueberries tend to distribute more evenly through a small cake.
  • You can also gently crush a few blueberries before folding them into the batter. This creates beautiful little streaks of purple-blue color throughout the cake.

Ripe Banana

  • A ripe banana is ideal because it is easier to mash and naturally sweeter.
  • Look for a banana with a few brown spots on the peel. It does not need to be extremely soft but a ripe banana will blend smoothly into the batter.
  • The banana also helps keep the cake moist.

Peanut Butter

  • Peanut butter adds richness and a flavor that makes this cake feel extra special.
  • Because peanut butter is rich you do not need much. Just a couple of tablespoons give the batter a lovely nutty aroma and flavor.
  • Again always make sure your peanut butter is free from xylitol.

Instructions
 

Step 1: Preheat the Oven

  • Preheat your oven to 350°F (175°C).
  • Prepare your small cake pan by lightly greasing it or lining it with parchment paper.
  • I recommend using parchment paper if possible because it makes removing the cake much easier.

Step 2: Make the Oat Flour

  • Place the rolled oats in a blender or food processor.
  • Blend until the oats become a fine, flour-like texture.
  • It does not have to be perfectly powdery. A little texture is completely fine.
  • Transfer the oat flour to a mixing bowl.

Step 3: Mash the Banana

  • Peel your ripe banana and place it in a separate bowl.
  • Mash it thoroughly with a fork until mostly smooth.
  • A few small lumps are perfectly fine.
  • The mashed banana will add moisture and natural sweetness to the cake, so make sure it is evenly mashed before mixing.

Step 4: Mix the Wet Ingredients

  • Add the mashed banana, egg, peanut butter, and water to a large mixing bowl.
  • Stir everything together until the mixture looks smooth and well combined.
  • The peanut butter may take a little extra stirring, especially if it is thick.

Step 5: Add the Oat Flour

  • Add the blended oat flour to the wet ingredients.
  • Stir gently until a thick batter forms.
  • The batter should be scoopable and moist but not dry.
  • If it looks too thick, add a tiny splash of water.
  • Avoid adding too much liquid because the blueberries will also release moisture while baking.

Step 6: Fold in the Blueberries

  • Gently fold the blueberries into the batter.
  • Try not to crush all of them.
  • I like leaving most of the blueberries whole because they create those lovely juicy pockets inside the finished cake.
  • Save a few blueberries if you would like to decorate the top later.

Step 7: Fill the Cake Pan

  • Spoon the batter into your prepared cake pan.
  • Use a spatula to smooth the top.
  • You can gently tap the pan on the counter once or twice to help settle the batter.
  • Because this is a small cake, it should not need a long baking time.

Step 8: Bake the Cake

  • Place the cake pan in the preheated oven.
  • Bake for approximately 20 to 25 minutes, or until the center feels set and a toothpick inserted into the middle comes out mostly clean.
  • Remember that baking times can vary depending on the size and material of your pan.
  • The top should feel firm but not hard.

Step 9: Cool Completely

  • Remove the cake from the oven and allow it to cool in the pan for several minutes.
  • Then carefully transfer it to a cooling rack.
  • This step is important.
  • Do not add yogurt or peanut butter topping to a warm cake because it can melt and slide off.
  • Allow the cake to cool completely before decorating.
