No Hand Mixer Needed Here

I really don’t like using a hand mixer often, to be completely honest. It’s just more quicker to make a recipe (cake, cookie, etc.) without it. And there’s less to clean-up afterwards.

Now, that’s not to say that I never use a hand mixer. For certain recipes (such as frosting), you absolutely need one to whip all the ingredients together very quickly.

Super Easy to Make Recipe..

Basically all you need to make this healthy vegan peanut butter oat cake is a large mixing bowl, a measuring cup/measuring spoons; and you’re good to go! Oh, and of course you need something to stir it all with. I usually use a fork to stir the dry ingredients first.

After adding in the wet ingredients, I use the same fork to combine everything together. Finally, I use a large spoon to stir the batter all the way to the bottom of the bowl (gently). This helps to ensure that all of the flour is thoroughly stirred into the batter.

*I was inspired by Amy from Amy’s Healthy Baking to use a fork to stir most of my recipe batters – be it cake or cookie batter, etc. It sure beats getting out a hand mixer (just my personal opinion)*

Vegan vs Non-Vegan

If you didn’t know already, I love creating vegan recipes, even though I still eat dairy and meat on occasion. You can eat healthy being vegan and non-vegan. I would label myself as being *half-vegan*.

As with this healthy vegan peanut butter oat cake recipe. It calls for you to use dairy-free milk predominately (since it’s a vegan recipe). But even a non-vegan person can make this cake by just using just regular milk instead.

Before I started using only almond milk in my recipes and daily eating, I would use 1% dairy milk. Actually, I started out using 2% milk, then I found out that 1% milk was even healthier; so I transitioned to that. I’m not against using regular *dairy* milk even now.

I just prefer almond milk because it’s more healthier than dairy milk overall. And you can use it in place of dairy milk, with only a barely detectable difference in taste.

Lack of Certain Nutrients

Now, most fully vegan people are totally against eating meat or any dairy products at all. On the other hand, I’ve read plenty of stories about vegans who left the vegan lifestyle, and turned to eating meat/dairy again.

They found out that their body required certain nutrients that only meat can give, such as protein and iron. These two nutrients help to provide much needed energy to the body.

Therefore, many former vegans have now embraced eating meat again. Just goes to show that it’s not good to judge someone’s eating habits without knowing the history behind it.

Vegan Peanut Butter Oat Cake Ingredients:

I’m sure you already have most of the simple ingredients needed to make this healthy vegan peanut butter oat cake:

  • Oat Flour: If you’re not sure what oat flour is – it’s just oats blended into flour. I prefer to buy my oat flour because it’s easier for me at this time. It’s sold in most grocery stores nowadays.
  • All-Purpose Flour: I didn’t want to use just oat flour in this cake. I combined the oat flour with regular all-purpose flour to ensure a light fluffy texture. By only using oat flour – the texture of the cake would be more dense and not as light.
  • Salt
  • Baking Powder
  • Baking Soda
  • Coconut Sugar: The caramel flavor of this sugar is perfect in this cake. You can try using regular sugar, but I don’t know how the flavor would be. Let me know how it turns out for you if use regular sugar..
  • Creamy Peanut Butter
  • Unsweetened Applesauce: Did you know that you can substitute applesauce (unsweetened) for oil and butter in many cake recipes? It changes the texture the more you use though. I would only replace up to half the amount of butter/oil with applesauce.
  • Vanilla Extract
  • Apple Cider Vinegar: Aids the baking powder and baking soda in helping the cake to rise and be fluffy.
  • Milk: Dairy-free or regular milk can be used.
  • Cinnamon: The cinnamon adds a subtle complementary cinnamon flavor to the cake.
