Alright, ready to mix up these homemade oatmeal cookie muffins? First off, you’re going to grab 1 cup of rolled oats (the not-instant kind, please instant just won’t give you that chewy vibe we’re after). Toss those into a big mixing bowl with 1 cup of all-purpose flour, 1/2 teaspoon each of baking powder, baking soda, and salt, along with 1 teaspoon of ground cinnamon.
To easily incorporate ingredients and achieve the perfect batter consistency, a Stand Mixer with a Paddle Attachment can be a game-changer for your baking.
Whisk that dry crew together real good to evenly spread all those warm spices and leavenings. Smelling that cinnamon already? Yep. That’s your signal that things are about to get delicious.
Now, in a separate bowl, it’s time for the wet stuff: 1/2 cup of melted and cooled unsalted butter your absolute key to moist, not dry muffins joins forces with 2 large eggs and 1 teaspoon of vanilla extract. Beat those together until they’re all friends and smooth.
Then, slowly pour in 1/2 cup of packed brown sugar and 1/4 cup of granulated sugar. You’ll want to mix just until the sugars dissolve a bit and the batter looks creamy, but don’t overdo it overmixing could mean tough muffins, and nobody wants that. Once your wet ingredients are cozy, fold in the dry mix gently, stopping as soon as no streaks of flour remain.
If you’re feeling adventurous, this is when you’d sprinkle in up to 1/2 cup of raisins or chocolate chips. Think of it as the “extra credit” on your muffin report card.
Getting ready for the bake? Spoon your batter evenly into a muffin tin lined with paper cups or greased well fill each about two-thirds full to give enough room for those muffins to rise without giant overflow drama.
Pop them into a preheated oven at 350°F and bake for about 18-20 minutes. Keep an eye on them starting around 16 minutes because ovens can be sneaky little tricksters. You’ll know they’re done when the tops are golden and a toothpick poked into the center comes out clean or with just a few moist crumbs no wet batter allowed.
Let them cool in the pan for 5 minutes, then move them to a wire rack if you’ve got one, because nobody wants soggy muffin bottoms. Serve warm or at room temp, and try to save some for later though, if you’re anything like most people, that’s wishful thinking.
