2-Minute Rice Krispie Treat in a Mug [+Video]

If you have 3 simple ingredients and 2 minutes to spare, then you are on your way to a single serving rice krispie treat in a mug! Satisfy that sweet tooth the right way!

Kids love them. Adults love them. They are a great dessert to feed a crowd. Our brown butter dulce de leche rice krispie treats are just about the best thing you will ever taste in your life! And if you want just a classic rice krispies treat, we’ve got you covered there too! But what if you just need a quick Rice Krispie treat fix and don’t want a whole pan of them tempting you all week long?

My sister and her family make little single serving Rice Krispie treats so that they don’t have a bunch of dessert sitting around that everyone keeps munching on. I thought it was such a great idea!

Here is a special glimpse into a typical evening in the Cheney household. We get the kids down for bed, and all we want to do is sit down with a sweet treat and veg!  Is this how it is at your house too? Or are we the only ones? The problem is that most sweet treats come in large quantities. This Rice Krispie treat in a mug for one has been our go-to lately!

The other problem is that we have no time to veg! After the kids are in bed is our prime time to jam out most of our work on the blog. But we aren’t complaining! There is something so fulfilling about being productive with your time! Don’t get me wrong, we quite often turn on some Netflix in the background.

Rice Krispie Treats – A History

Can you guess what year Rice Krispie treats came to be?  I had no clue, but it was a lot earlier than I expected! According to Wikipedia, Rice Krispie treats were invented in 1939 in the home economics department of the Kellogg Company as a fund raiser. That means there has been 85 years of Rice Krispie treats magic!  Everyone should make this Rice Krispie treat in a mug to celebrate!

Rice Krispie Treats for Special Diets

You can buy Rice Krispies that are gluten free. Just make sure the box says “Gluten Free” on the front.  They are different than your regular Rice Krispies. The Great Value Walmart brand is my go-to!

Butter and marshmallows are gluten-free. That is great news for our gluten free friends!  However with the butter in there, it is not dairy-free.  There is an easy solution for that…just replace the butter with coconut oil!  It works like a charm and still tastes like the Rice Krispie treat you know and love!

Brown Butter Dulce de Leche Rice Krispie Treats

Brown butter dulce de leche Rice Krispie treats start as a traditional Rice Krispie treat that gets elevated to the next level! The nuttiness from the brown butter with the creamy sweetness of the caramel all wrapped around the crunch of the cereal…I’m going to be bold and say it will be the best Rice Krispie treat of your life!

Kerri here! You might remember me from the world famous gingerbread men cookies and the caramel Bugles. Head over to those posts to read about who the heck I am…haha! Anyway…I told Carrian that she had to try this new recipe I had come up with because it was the most amazing Rice Krispie treat I had ever had. Side note…can we just call them RKTs from now on? Rice Krispie treat is such a mouthful!

Afterall, it was her RKTs recipe that was the base of the recipe in the first place. She made my brown butter dulce de leche version, and photographed them. And here we are! She had cinnamon sugar Rice Krispies in the cupboard and she swears by the cinnamon sugar! I can’t wait to try it that way!

How This Recipe Came to Be

This all started with a trip to Blox, a restaurant here in Utah that specializes in dessert bars. We tried one of their Rice Krispie treats one time, and I could tell immediately that it was made with brown butter and I was hooked for life. Then I thought, I should stuff some dulce de leche in the middle of this gooey RKT.

We love dulce de leche here at Oh Sweet Basil, and Carrian is always stuffing it into delicious recipes to make them even more outrageous, so I probably should do the same! So the RKTs were stuffed (or layered really) and minds and tastebuds were blown! I’ve made them a few times now for different events and every single person has wanted the recipe. I absolutely love that they will live here now and I can just send people a link to the recipe rather than explaining all my steps.

Ingredients for Browned Butter Dulce de Leche Rice Krispie Treats

You only need 6 ingredients and about 10 minutes to have these RKTs ready to go!

• Butter: I prefer to use unsalted butter so that I can control the salt in the recipe. The first step in this recipe will be browning the butter. I describe how to do that below.
• Vanilla Extract: Use real vanilla extract for maximum flavor.
• Mini Marshmallows: You want to use mini marshmallows so that they can melt quickly and evenly.
• Rice Krispies Cereal: I’ve only ever used regular Rice Krispies, but Carrian used the cinnamon sugar flavored and says that’s where it’s at! I trust her and will be trying it next time. It gives it a churro flare and churros never disappoint! Use either one and you won’t be disappointed!
• Sea Salt
