Keto Lemon Mug Cake Recipe Procedures

Step 1

Now, to make Keto Lemon Mug Cake, you’re going to need a mug. I recommend using at least an eight-ounce profile so that the cake does not spill over when it’s cooking.

And you do want to grease the mug before you put the cake mix in there. So I like to rub a little bit of coconut oil in here. Butter would work, ghee would work, or even a little bit of cooking spray. So use whatever you have. We want to make sure that our cake doesn’t stick to the mug.

As for our ingredients, you could do this right in the mug, but I find it a little bit easier and a lot neater to do on the side and then transfer it into the mouth.

So I’m a big fan of these spouted glass measuring cups, and that’s what I’m going to use today. So the first ingredient going in is a quarter cup of almond flour.

Next, I have two tablespoons of Monk fruit sweetener. I am a big fan of these Monk fruit blends. It’s a mix of Monk fruit extract and erythritol. So it’s an all-natural, no-calorie, no-sugar sweetener. That stubs one for one with any granulated sugar.

Step 2

So it works whenever you’re doing a baking recipe like I’m doing here today. You can sub any granulated sugar you have on hand if you prefer. I like the Monk fruit. The flavor is great, and I like that it doesn’t affect blood sugar levels. Then I add one teaspoon of melted coconut oil.

It could also be melted butter or ghee, a quarter teaspoon of vanilla extract, one beaten egg. You want to mix it well before getting it in; there is a quarter teaspoon of baking powder.

So our cake is nice and fluffy. Then I have a tablespoon of fresh-squeezed lemon juice and one-two, a teaspoon of lemon zest. Now quick chef’s tip, make sure that you zest your lemon before you juice it this way, you get the most out of your lemon, and when you’re resting, once you get the bright yellow, Peel off, you want to stop.

Okay, so any of this pithy white part that’s a bit bitter. You don’t want to zest through that. Okay. You want the nice bright oils from the lemon rind, and we want to leave the pits behind.

Step 3

So I’m going to mix this all together and whisk it well gently, so there are no clumps in there or almost no lumps in there, and you’ll have this nice, lovely cake batter Just as I have here.

It should be pretty much the same consistency as if you were making a cake. Then I’ll transfer this into my prepared mug and pop it right into the microwave for 1 minute.

Now, do note that all microwaves vary. My microwave does not have a high or low setting. So it’s one size fits all, and I Cook this cake for 1 minute, and it’s just perfect, but you’re going to want to play with it.

Depending on your microwave, you will know your cake is made and ready to go because through it will have risen, and it’ll be a little bit springy on the top, Just like a regular cake would be.

Of course, once it’s cooled down just a little bit, you could enjoy it just the way it is but my favorite way to enjoy it is with a little dollop of plain Greek yogurt and then some fresh berries over the top.

It’s so bright, it’s so delicious, and it is perfect whether you want a little sweet treat on your own or even if you want to make it for the family or some guests after dinner and for those of you who prefer vanilla or a chocolate mud cake I have your back.
