How to make flourless mug cakes

Turns out nut or seed butter + eggs makes pretty amazing (and simple!) mug cakes. Plus, that base immediately makes the mug cakes gluten free, paleo-friendly, and keto!

My goal while creating these treats was to keep them as simple as possible while not sacrificing flavor or texture. And after many, many tests, I nailed it!

So these simple flourless mug cakes start with a little coconut oil, SunButter, and eggs. Once that’s stirred until smooth, add coconut sugar, baking soda, and a pinch of salt. Finally, stir in a swirl of strawberry jelly.

A minute in the microwave, and we’ve got mug cake magic!

Notes on ingredients for SunButter and jelly mug cakes

Before I get to the recipe, I want to share a few notes about choosing ingredients.

First, lets cover swaps to make these mug cakes keto-friendly. Coconut sugar, from what I understand, isn’t widely used in keto. You should be able to substitute it for the equivalent amount of monk fruit or stevia.

Next, let’s talk SunButter. Since SunButter sponsored this post, I obviously used SunButter to make the mug cakes. I have no idea if it will work with other brands or nut butters.

Some brands add extra oil into their butters while grinding, but SunButter doesn’t — which is one of the reasons I love them — so if you use another kind, extra oils can mess with the overall texture. After all, with mug cakes, every adjustment matters. Even a slight adjustment can change everything!

My final ingredient note tackles the jelly! I know, it can be a struggle to find sugar- and junk-free jams or preserves. But that’s the way to go here! My favorite to reach for is St. Dalfour’s strawberry preserves, and I’ve seen them in quite a few stores (a feat in the Fargo-Moorhead area).

Why SunButter?

So, with all the nut and seed butters on the market, why use SunButter?

SunButter has been on my radar for years as a peanut butter alternative. I have a cousin who was deathly allergic to peanuts as a child, and my aunt was thrilled to discover SunButter. Not only is it a local company (based in Fargo, ND!), but they’re committed to simple and natural ingredients. No fillers or added oils!

And while I mentioned using SunButter as a PB alternative, that’s not the only allergy that can drive people to look for other options. I hear from people frequently who have a tree nut allergy, meaning almond butter and other popular nut butters are out. SunButter fills in there, too!

Because SunButter’s sponsoring this post, I’ve got a special goodie for you: a print-at-home coupon good for $1 off any SunButter product!

SunButter makes the perfect nut free, gluten free, and paleo mug cakes for two. See the notes below for how to make keto-friendly swaps, too!


  • 2 teaspoons coconut oil, melted
  • 1/4 cup organic SunButter
  • 1 egg
  • 1 tablespoon coconut sugar
  • 1/8 teaspoon baking powder
  • 1 pinch sea salt
  • 1 tablespoon strawberry jam


  1. Add coconut oil, SunButter, and egg to a mug or small mason jar. Mix until smooth. Add coconut sugar, baking powder, and sea salt, stirring until fully incorporated. Add jam and stir a couple times to create swirls of jam, being careful not to mix it completely with the batter. Microwave for 1 minute. Drizzle with extra SunButter and jam, if desired, and serve immediately.


To make these mug cakes keto-friendly, swap out the coconut sugar for the equivalent amount of monk fruit sweetener.
