Tips for Eggless Peanut Butter Sheet Cake

• Make sure your butter is soft. When cakes call for soft butter, it's truly needed. I like to leave butter out on the counter overnight to soften naturally as I feel it gives it the best consistency. But, as the weather starts to get colder, you may have to microwave it. Only microwave 10 seconds per 1/2 cup, otherwise portions of the butter can melt.

• Use room temperature applesauce and milk as this will prevent your butter from clumping up. Since you already used soft butter and creamed the butter and sugar together, the milk and applesauce should be room temperature so it easily mixes in. This is going to help give your cake the best texture and crumb. If you use cold ingredients here, and the butter clumps, then that can leave your cake with an undesirable texture.

• Use high quality organic peanut butter! This is a peanut butter cake – all peanut butter. So this ingredient really matters. There are so many peanut butters that are different in flavor, so make sure to find one that you like best. I like to buy organic peanut butter that only has two ingredients: peanuts and salt. My two favorite options are Kirkland Organic Peanut Butter and Smuckers Organic Peanut Butter. They have the absolute best flavor, in my opinion.

• Allow your cake to cool completely before frosting it. I know this can be difficult, but it's truly necessary so the buttercream doesn't melt.

• Make sure to use roasted and salted peanuts for the topping. These bring more flavor and salt to the finished cake, so that's why it's important. Raw peanuts will not be the same here.

• Make sure to store this in an airtight container so it stays fresh for days. This is an amazing snack cake to take with you anywhere!

Why organic?

Why use organic ingredients in this recipe? You all know I’m a huge organic advocate, and I bet you may be thinking sometimes, Why would I even bother to use organic ingredients in something that is so sweet and indulgent? But, that is the exact reason why you should use organic ingredients! Sweet things need to have flavor in order to be good, otherwise they are just sweet and they don’t taste like much else. Organic ingredients are more pure than conventional ones, therefore they actually have more flavor than the non organic options. Say it with me, organic means more flavor! And not just more flavor but a more true and pure flavor. And organic ingredients are much healthier for you to eat in general as they do not contain GMOs or anything artificial. Plus, you are being environmentally friendly when you choose organic ingredients!

So, I highly recommend that you buy the best organic ingredients for this recipe! You can also shop my Amazon Storefront for all my favorite organic ingredients here. Tip – hover over each ingredient to see the name. And if you want to learn more about organic foods and the difference, read my post here on Food Labels and What They Mean.

    I have been told that at 8500 ft. I should never use cake flour – it is not strong enough to hold the rise. Also, I wonder about reducing the amt of leavening to 1/4 tsp at my altitude? What are your thoughts?

    • mimibakescookies

      Hi Denise! I’m so sorry someone told you that, as that’s not true at all! I am at 8,000 feet where I made this cake last week. I do not believe you need to reduce the leavening and I think you should try this recipe as is. I have people who live at 9,000-10,000 feet make my cakes without issues. I’m always happy to help troubleshoot if you do have a problem, feel free to email me at hello@mimibakesphotos.com. I’d love to hear how it turns out! Happy baking!
