Crock Pots or slow cooker, whatever you like to call them, are awesome to use for savory meals. But once you venture to the dessert side, you will be surprised at how quickly you will be hooked to making this for friends and family. As long as you're not looking for a perfect looking cake, neat and tidy kind of cake and you're more interested in a simple, but tasty treat for family and/or company, desserts in the crock pot are the way to go.
Dump, make sure it's plugged in, cover and set! Come back in a few hours for some deliciousness!
Coconut is NOT a Nut
My youngest child, who is quite the coconut hater, can't tell this slow cooker cake is made with coconut, and that has been what has driven me to continue to persevere with coconut flour. Youngest has a tree nut allergy so very often I've got to make low carb recipes using coconut flour as opposed to almond flour. Often he can detect it and makes complaints. But not this year folks, not this year. I am winning 5 out of 5 thus far!
I'd like to clear up this constant question get asked almost daily about whether coconut is a nut. While the US Food & drug Administration (FDA) claims that coconut is a tree nut becomes it comes from a tree, it is in fact a FRUIT. People who have tree nut allergies may be allergic to coconut as well, but being allergic to coconut is not the same as having a tree nut allergy.
My own son was diagnosed with a Peanut and Tree Nut allergy at the age of 2. He has safely eaten coconut all these years without issue and he is now 14. Coconut is a fruit, called a drupe. It's like a peach with a pit.
The American College of Allergy, Asthma and Immunology says it well: "Coconut is not a botanical nut: it is classified as a fruit, even though the FDA recognizes coconut as a tree nut. While allergic reactions to coconut have been documented, most people who are allergic to tree nuts can safely eat coconut. If you are allergic to tree nuts, talk to your allergist before adding coconut to your diet."
I've made a Chocolate Tiramisu Cake Roll, Low Carb Cheddar Sausage Bagels, Tiramisu Mug Cake Low Carb Banana Cream Pie Cupcakes and now this and he's had no idea!
Easy Slow Cooker Cake
Tastes like a custard, formed like a cake! Easy to make, no oven required! Set it and forget it! Top with some sugar free whipped cream and a few berries and call it a day!
Brenda's Notes:
- You can substitute the swerve sweetener with another sugar free sweetener of choice, but often other brands are sweeter so I would either use ¼ cup of something else or eliminate the lemon stevia.
- You could even use canned coconut milk in place of the heavy cream and make it dairy free.
- If you're not a fan of lemon as much, reduce the amount of juice I used here to just ¼ cup.
- If you're not much of a fan of lemon than perhaps you'd like my Crock Pot Fudge.

I just made this today, and we love it! Thanks so much for the recipe! I baked it in a 350 degree oven for 30 min. in a 9x13 pan, just as you suggested. I also left out the liquid stevia. I didn’t have any lemon stevia anyway. We like the sweetness with just the Swerve, as it turns out. Very lemony and delicious. What a treat! We didn’t even wait for it to cool and be refrigerated either. Fantastic...
Leslie
QUESTION: For those that baked it in the oven, did you cover the 9x13 dish with foil so that it baked like it would have in the crockpot? I baked it uncovered and it came out crumbly and just a bit dryer than I anticipated; still FABULOUS, though! 🙂

Tried it last week and it was fantastic! It was a little browned on one side of slow cooker bowl but it was edible and it added some flavor to it. Two things I did apart the recipe are: I added vanilla flavor into mixture and cooked the remaining blueberries to turn them into glazed. Every time I took out a slice, I would add glazed blueberry on it. Thanks!!
Caroline
Thanks -this is just what I needed today as my gf daughter (and newly df) was upset this morning that, again,her siblings got to eat something she couldn't (porridge). She loves lemon and will be so happy tonight when she gets this as a special treat. I'm interested if her big sister likes it as she normally doesn't like coconut - fingers crossed she doesn't notice it .
Mary
I love lemon everything. And love your recipes. I don’t have lemon stevia but I do have the plain and the vanilla. Do you think if I use the plain stevia and tsp of lemon extract I would achieve the same results. Thank you.
Esther
I know this is a crazy question, but I was wondering if you or any of your readers might have an answer for me. I love the taste of lemon (and really miss it) but I get headaches if I eat too much of it. Lemon rind doesn't bother me like the juice does so I bought some lemon extract (which is basically lemon oil from the rind and not the juice) and am just beginning to experiment with it. If I substituted the 1/3 cup lemon juice with a liquid (water? almond milk?) and replaced the lemon liquid stevia with the lemon extract, how much do you think I should use? Should I replace the lemon juice with something else tarter (vinegar?) Eek, I'm hopeless at substituting things and would appreciate a little guidance if anyone has any ideas.
thanks in advance.
Brenda
Maybe sub 1/3 lemon juice with water and add 1 teaspoon lemon extract. You can't replace the liquid lemon stevia with just lemon extract because there is no sweetener in lemon extract. The liquid stevia is quite sweet but if you can't have that try Swerve confectioners sweetener, sadly though it is only 70% as sweet as sugar so you may need to use 1 cup of it.
Carmen
Well I baked it in the oven at 350 for 30 minutes, came out perfect. Anxiously waiting now for the two hour refrigeration. I will post again after I indulge. LoL
Carmen
This cake turned out awesome! Thank you for the recipe.
Carmen
I'm pretty sure it calls for 2 cups heavy cream right?
Lisa
Looks great
What about half and half?
Brenda
That could work too.
