Keto Microwave Bread with Lupin Flour

This is by far the best keto microwave bread I have ever tried, and I think a big reason it works is I’m using lupin flour, my favorite low carb flour that’s also gluten-free, made from the lupin bean. I’ve made lots of different versions of 90-second bread, trying to replicate the softness of a couple slices of bread I might use for sandwiches. This one is a winner for several reasons, high on that list is the perfect texture and the fewer number of ingredients compared to other recipes I’ve created.

There are literally only five ingredients in this lupin flour microwave bread. It is so soft and fluffy that I could eat it right out of the mug without having to toast it first, which is another first for me as far as microwave bread goes.

Speaking of the mug, keep in mind that this microwaved bread comes out more like a muffin than a loaf of bread. That is directly connected to the fact that you cook it in a coffee mug like you would a mug cake. So, sure, you can slice it to toast it but keep in mind how little it is when done.

Each serving has a net carb of two grams and it’s relatively high protein, with 6 grams there. It’s perfect for those on keto diets who still want the taste and experience of having bread of one sort or another.

If you like how lupin flour works in a mug in the microwave, then you’ve got to try making a whole loaf of lupin flour bread. You’ll make it in a traditional loaf pan in the oven and I promise, you’ll love this low-carb bread, too.

Dry Ingredients and Wet Ingredients

  • 2 tablespoons Lupin Flour
  • 1 teaspoon baking powder
  • 1 tablespoon heavy cream
  • 1 egg
  • 1 tablespoon melted butter

Step-by-Step Instructions for this Keto Bread Recipe

  • Prep Time: 2 minutes
  • Cook Time: 2 minutes
  • Total Time: 4 minutes

I start by melting my butter in the microwave for 30 seconds in the mug I’ll be using. Then I pile all other ingredients for the batter in, stir well and then microwave for 90 seconds until it is golden brown.

You can add other ingredients if you’d like, perhaps a bit of cheese, some garlic salt or some monk fruit sweetener and vanilla extract for a quick microwave cake! But as is, this is great.
