Gluten-Free Plum Cake

This gluten-free plum cake is sweet, fragrant, and delicious. The combination of vanilla and ripe, juicy, fresh plums is just right. This nutritious cake is also dairy free, refined sugar free, and paleo diet friendly. This cake is easy to make and delicious.

Main ingredients and substitutions

I prefer to use red plums in this cake. Their color is so pretty and I love their flavor as well. But any type of plum will work, so use whatever is fresh, ripe, and seasonal.

This cake recipe would be delicious with other varieties of stone fruit such as nectarines or peaches (or really any type of fruit imaginable), so feel free to substitute.

This recipe is sweetened with maple syrup but you can substitute honey if you prefer.

This gluten-free plum cake is flavored with pure vanilla extract. It’s important to use the pure extract as opposed to artificial vanilla flavoring if possible. You can really taste the difference. Alternatively you can substitute the seeds of one vanilla bean pod.

This recipe calls for coconut flour and I don’t recommend substituting any other types of flour. Coconut flour is much more absorbent than other flours and works best when combined with a lot of eggs (this cake requires five eggs and I don’t recommend substituting those either).

I used extra virgin olive oil as the fat in this cake. You can substitute any other oil you prefer (or melted butter if you don’t need this cake to be dairy-free).

How to make this gluten-free plum cake

This cake is quick and easy to prepare. Start by preheating the oven to 350 degrees Fahrenheit, then wash, dry, and thinly slice the plums.

Add the eggs, maple syrup, extra virgin olive oil, pure vanilla extract, and salt to the mixing bowl and use a whisk to mix well.

Add the coconut flour and baking powder, then whisk some more to combine.

Next you’ll grease a nine inch baking pan with extra virgin olive oil (I used a round pan but any shape is fine) and place a piece of parchment paper covering the bottom of the pan.

Alternatively you can use a springform pan if you prefer (this makes it easier to remove the cake from the pan and transfer it to a pretty cake stand for a special occasion).

Transfer the cake batter to the pan and use a spatula or the back of a spoon to spread it in an even layer. Then add the thinly sliced plums on top. You can create a symmetrical pattern with the plum slices for a fancier presentation or just place them randomly for a more rustic look (I opted for rustic this time).

Bake the cake at 350 degrees Fahrenheit for 45 minutes. Then let the cake cool off before serving.
