You Can Have Your Cake and Eat It Too!! If you follow this Keto blog you will see that I LOVE Lemon Flavored Desserts and this low carb Olive Oil Cake is ant the top of that list!

Let me start by saying that I’m not a baker, it requires patience, attention to detail and following direction, I possess none of these qualities. That being said I do love to eat cake so since my local grocery store doesn’t sell low carb olive oil cakes and I don’t feel like spending a fortune on one of those tasty Keto desserts online I sucked it up and got to baking. One of the worst parts of creating a recipe from scratch is that it could go wrong at any time especially when your trying a new method of cooking but fear not I’ve taken all the risks and you get to reap the rewards. This cake exceeded all of my expectations, moist cake texture with a cream cheese frosting that will knock your socks off. Out of all the recipes I’ve made this is probably my favorite in the dessert category.

It’s summertime and I like lighter desserts so I knew I wanted to use lemon, I’ve made lemon muffins before but wanted to step up my game and get a little creative. Basically I took a zucchini bread and a lemon olive oil cake and used my favorite elements from both. I could have stopped there and this would have been a great moist cake that anyone would enjoy but I decided a cream cheese frosting would take this cake over the top. As I mixed in the sweetener with the cream cheese and added the lemon I remembered that I had a shot of limoncello leftover that was just taking up space in the liquor cabinet. This was the piece de resistance if you will, the extra hint of lemon that made me want to take a spoon and start shoveling mounds of frosting down my throat, but fear not, I mustered up some self control and forged on. To be clear there are seven carbs in a shot of limoncello and you can totally replace it with an 1 oz. of lemon juice but the limoncello only adds about a half gram of carbs per serving and I deemed that acceptable for me.

One quick tip, if the cake is getting brown on top and not completely done in the middle you can leave the cake in the oven and turn it off, let it continue to cook but don’t open the door and let all the heat out.
