A Quick Summer Dessert Recipe Using Organic Ingredients
Picture this:
It’s late afternoon, the cicadas are buzzing, and you’ve got a hankering for something sweet—but not too fussy.
That’s where these Oatmeal Cream Pie Cupcakes come in.
I’ve always had a soft spot for the kind of desserts that remind you of simpler times. The kind you’d unwrap at the lunch table, traded only if you were feeling real generous.
These cupcakes? They’re that nostalgic flavor—grown up a bit, and dressed for summer.
The recipe is downright beginner-friendly. No fancy tools or special skills needed. Just a few pantry staples, a warm oven, and a little heart.
We use our Organic All-Purpose Flour right here on the farm to give these cupcakes their soft, fluffy base.
Rolled oats and a drizzle of molasses bring that old-fashioned goodness, and the marshmallow cream center? Let’s just say your inner kid is going to do a happy dance.
As baker and cookbook author Erin Jeanne McDowell once said:
“The best desserts feel like a hug. The rest is just sugar and technique.”
This post will walk you through every step—from mixing to filling—with tips just for beginners. Whether you’re baking for your grandkids, a summer potluck, or just a quiet moment on the porch, this one’s for you.

Oatmeal Cream Pie Cupcakes FAQs
For a tender, fluffy texture, I recommend using our Organic All-Purpose Flour. It’s stone-milled right here on the farm, preserving the natural nutrients and flavor. This flour provides the perfect balance for these cupcakes, ensuring they rise well and have a soft crumb.
A simple test: gently press the center of a cupcake with your fingertip. If it springs back, they’re ready. If it leaves an indentation, give them a couple more minutes. Alternatively, insert a toothpick into the center; if it comes out clean, the cupcakes are done.
Absolutely. You can cream the butter and sugars by hand using a sturdy whisk or wooden spoon. It might take a bit more elbow grease, but it’s entirely doable. Just ensure the butter is softened to make mixing easier.
