Marshmallow Swirl Sweet Potato Muffins

Swirled with marshmallow and filled with your favorite fall spices, this recipe for Sweet Potato Muffins is meant for early autumn. Great for breakfast, midday snacking and also making ahead, these flavorful muffins bake up perfectly and stay soft for days.

Let’s talk muffin tops.

Two words that used to be associated with the tastiest part of a muffin are now slang for squeezing into a pair of too-tight, hip-hugging pants. The paradox of skinny jeans is they make all the fat in a woman’s belly bulge over the top of her waistband like a baked muffin over the top of its wrapper.

Obviously it’s a confectionery metaphor we could do without.

Arguably crummier than a muffin top is a stud muffin top, when the same, belly-busting affliction is suffered by a hot guy. Then there’s the worst-of-the-worst: the English muffin top, a euphemism for visible nooks and crannies in the fat overflow. I’m still deciding who should be more offended by that, the British or the Thomas’ English muffin makers.

Regardless, protruding midriffs have given muffin tops a bad name. If you’re wiggling and jiggling into jeans that are three sizes too small, don’t be surprised when your stomach looks like a mushroom cloud after an atomic bomb detonation. I’m not preaching, I literally had to be cut out of a pair of pants that squeezed me tighter than a boa constrictor.

We’re all guilty of paying the price for fashion, but the buck stops here. Today’s the day we say no to skinny jean muffin tops and yes to the tops on Sweet Potato Muffins. I mean, have you seen the sweet, gooey swirl on these muffins? They are a sugary work of art if I do say so myself–and I most certainly do.

If you’re a fanatic for pumpkin muffins, you’ll love these similarly flavored, but even more delicious sweet potato muffins. Filled with fresh sweet potato and your favorite fall spices these tender, marshmallow swirl muffins are meant for early autumn. Great for breakfast, midday snacking and also making ahead, these flavorful muffins bake up perfectly and stay soft for days.

Before sharing the recipe for Sweet Potato Muffins, here are a few tips and tricks to help you out:

Ingredient Tips

To bake your sweet potato before mashing, pierce a sweet potato all over with a fork then bake at 400 degrees for 45 minutes. After cooling completely, scoop out flesh, mash and measure 1 cup before adding to muffin batter.

Eggs need to be at room temperature before use. If you’ve forgotten to take your eggs out ahead of time, speed up the process by placing them in a bowl of warm water. Don’t use hot water; we want to warm the eggs, not hatch them.

Always use the spoon and level method to measure flour. Scooping flour is a no-no because it overpacks flour into the measuring cup which will result in dry, dense muffins.

Preparation Tips

This Sweet Potato Muffin recipe is so simple that you only need two bowls, a whisk and a spoon.

How to Store Sweet Potato Muffins

Cover muffins with plastic wrap then store at room temperature up to 3 days.

Can you freeze muffins? Yes! To freeze sweet potato muffins simple place them in a single layer in an airtight container and store up to 2 months.
