Our plum tree has been producing an abundance of ripe, juicy plums this summer! We are super excited because in the past the squirrels get to them before we get to enjoy any fruit. So not only am I really excited to share some awesome plum recipes, I am even more excited to eat them.

Our little plum tree is in a happy spot in our backyard. This is just a few branches because our tree grew like crazy in just a few months. I am going to have to prune it a lot in January because the branches are really thin and tall.
Just wait because I will be making a lot of plum recipes in the next week as we can't give enough of our plums away...so stay tuned!
Are you ready to make this cake? Please know if you don't have fresh plums, there are so many other fruits you can substitute!!
This gluten free upside-down cake is really versatile. You can trade out the plums for other fruits if you want. Here are some ideas to try:
Add all of your dry ingredients to a bowl and whisk to blend.
I have tested two gluten free flour blends in this recipe. I liked King Arthur Gluten Free Measure for Measure and Bob's Red Mill 1 to 1 Gluten Free Flour Blend. This doesn't mean other blends won't work, I just haven't tested any others. Try to avoid flour blends that are high in starch.
Now, add your wet ingredients to the bowl and whisk.
Pour the wet ingredients over the dry ingredients and mix.
This is what your gluten free cake batter will look like. Now to prep the plums and pan. Cut your plums in half, remove the seed.
How many plums does this recipe call for?
How many plums you use will depend on the size of your plums. Our plums are tiny so I need to use a lot more. Store-bought plums tend to be a lot larger and so you will need fewer to cover the bottom of the pan.
I used a springform pan for this recipe but you can use any cake pan. Line the bottom of the pan with parchment paper. This will help you when it comes time to remove your cake from the pan.
Pour the cake batter over the plums and spread it around to evenly cover the plums. Bake at 350F degrees for 45 minutes.
When the cake is baked, remove it from the oven. I loosened the sides of the springform pan to allow it to cool faster. Next, put a plate over the top of the cake and flipped the cake over. Remove the bottom of the springform pan, then slowly (very slowly!) peel off the parchment paper. *Optional dust the cake with powdered sugar.
What Is Upside-Down Cake?
Basically, an upside-down cake is when the cake itself is baked on the bottom of a baking pan and then a layer of fruit is on top. When it’s time to serve the upside-down cake, you usually flip it so the cake is on top, and the fruit is on the bottom.
How do you now when upside-down cake is done baking?
You will know when this gluten free upside-down cake is done when you insert a toothpick in the center, and it comes out clean. As the cake bakes, you will notice the sides start coming away from the pan as well.
Do I need to refrigerate cake?
Most upside-down cake recipes should be refrigerated after they have completely cooled. The cake will last around 3 days in the fridge. If you prefer it to be warm, you can always toss it in the microwave for 20-30 seconds.
Can I freeze upside-down cake?
Yes, you can freeze this plum cake recipe. After it has cooled entirely, wrap it with plastic wrap or tin foil. Then place in an airtight container and put in the freezer it will last around 1 month.
