Lemon Meringue Cupcakes – Keto, Low Carb & Gluten Free

Lemon Meringue Cupcakes - Keto, Low Carb & Gluten Free

These lemon meringue cupcakes are just as delicious as they look!  I love all things lemon, I use it in my drinks, desserts and even savory dishes.  My mother is visiting from out of state and one thing I used to make for her was lemon meringue pie.  I wrote this recipe to make for her (she’s also on Keto and loving it) as a new twist on my traditional pie.  

Look at these gorgeous lemons I found at my grocery store!  This was the inspiration for my 5 Minute Microwave Lemon Curd.  I saw them and just had to make something fabulous with them!

5 Minute Microwave Lemon Curd - Keto and Low Carb

These are so fun and easy to make, and they are filled with my 5 Minute Microwave Lemon Curd, but if you’d rather use lemon curd make on the stovetop, you can use my recipe for Lemon Curd found here.  They both taste amazing, but for this recipe, I prefer the 5 minute method to save on time.

Ingredients:

1 cup 5 Minute Microwave Lemon Curd (or my traditional Lemon Curd)

For the Cupcakes

1 3/4 cups super fine almond flour

1/4 cup Oat Fiber (see note below)

2 eggs, divided

1/2 cup swerve confectioners

2 teaspoons baking powder

2 teaspoons lemon zest

2 tablespoons fresh lemon juice

Pinch of salt

For the Meringue Topping

3 egg whites

1/4 cup swerve confectioners

2 tablespoons swerve granular

1/4 teaspoon cream of tartar

Transfer the mix to a piping bag fitted with the tip of your choice.  If you don’t have piping tips, you can add to a food storage baggie, cut a hole at the tip and pipe on that way.

To Finish the Cupcakes

Increase oven temperature to 400F.

Add the lemon curd filling into a piping bag fitted with a large round rip.

Pipe the meringue over the top of the cupcakes, as if you were frosting them.

Place them back into the oven on the upper 2/3 rack and bake for 3-4 minutes or until the meringue is toasted.  Do not over-bake!!  If they bake too long, the tops will be more like meringue cookies, and not as gooey inside.  You want them just barely toasted on the outside.

Note:  

The Oat Fiber is really important in this recipe!  I use it in so many recipes, because of the amazing texture it gives whatever I am baking!  It is hands down, the best ingredient I’ve baked with and is really worth buying.  I use Lifesource Foods Oat Fiber 500 because they grind it to a very fine powder and has a mild flavor. I buy it in the 16 ounce bag here.  The bag lasts a while, because you don’t need to use much in your recipes.

Oat Fiber, is not the same as Oat Flour, which is made from grinding oats.  Oat Fiber is made from grinding the outside husks of oats and is pure insoluble fiber.  Insoluble fibers do not dissolve in water and are not broken down in the digestive tract. So it’s low carb and Keto friendly!

These are just some of the great recipes you can make using Oat Fiber:

Blueberry Lemon Muffins

Pumpkin Cupcakes

Chocolate Chip Cookies

Gingerbread Cupcakes with Cream Cheese Frosting 

Cheddar Jalapeño “Cornbread”

Blueberry Pancakes

Lemon Poppy Mini Bundt Cakes

Rosemary and Kalamata Olive Focaccia

Cinnamon Roll Waffles with Cream Cheese Icing

Lemon Cupcakes with Creamy Lemon Frosting

Chocolate Peanut Butter Cupcakes

Fluffy Pumpkin Pancakes

Pumpkin Donuts

Cranberry Sauce and Walnut Muffins

Tiramisu Pancakes

Recipe Notes

The Oat Fiber is an important ingredient in these cupcakes, as it adds such an amazing texture, unlike anything else I've ever baked with.  Therefore, I cannot say any substitution would suffice and still give you that great texture that makes these comparable to traditional cupcakes.  I use Lifesource Foods Oat Fiber 500 and I buy it in the 16 ounce bag on Amazon (link in recipe).
