    This gluten-free plum cake is crumbly, filled with fresh, ripe plums, and looks gorgeous topped with streusel and fresh whipped cream. This is my take on a gluten-free german plum cake.

    gluten-free-plum-cake

    This is a plum cake. Now, the traditional plum cake is made with a springform pan, but here’s the thing: I don’t have a springform pan. And the more I was thinking about it, I don’t think a lot of people have one unless they’re a serious baker. It's very similar to an upside-down cake.

    I want my recipes to be accessible and easy to make so I modified the recipe. So this is a non-traditional plum cake because it’s not made with a springform pan, but I think it’s absolutely delicious, and I think you will too! Plus, it's so easy!

    This gluten-free plum cake is inspired by my chocolate-covered pineapple bites and my gluten-free pear crumble.

    Ingredients

    ingredients
    • Plums: a must for this gluten-free plum cake recipe. These stone fruits are delicious!
    • Butter: unsalted and softened for the cake. Cold and cubed for the streusel.
    • Brown sugar: makes the streusel delicious.
    • Eggs
    • Almond flour: soaks up some of the excess moisture from the plums.
    • Granulated sugar
    • Gluten-free flour: I use Cup4Cup or King Arthur's Gluten-Free flour in this recipe.
    • Salt
    • Vanilla extract
    • Baking Powder: helps the cake rise.

    See recipe card for quantities.

    Instructions

    Preheat the oven to 350 degrees.

    Grease a 9-inch cake tin and line the bottom with parchment paper. Set aside.

    slice-the-plums

    Slice the plums in half, remove the pits, and slice them into wedges. Layer on the bottom of the cake tin. Sprinkle the almond flour evenly over the plums. Set aside.

    streusel

    In a medium bowl, make the Streusel. Combine cold butter, brown sugar, gluten-free flour, and almond flour. Use your hands or a pastry cutter to work the mixture into small pebbles.

    Sprinkle the Streusel evenly over the top of the plums. 

    In a large bowl, make the cake batter. Cream the softened butter and add the eggs and sugar.

    Add in the baking powder, salt, and gluten-free flour. Mix the dry ingredients in until combined. The batter will be sticky and thick. 

    Use a spoon to dot the cake batter over the plum/almond flour/Streusel layer. It will be sticky and hard to spread. Do your best to spread the batter evenly.

    Bake in the oven for 35 minutes. Let the cake cool completely, then flip over on a wire rack and peel the parchment off.

    Top with more sliced plums and whipped cream if desired.

    Hint: it can be helpful to grease a spatula with butter or cooking oil and use that to press and spread the cake batter over the Streusel/plum/almond flour mixture.

    How to put this cake together

    First, layer the plum wedges on the bottom of the cake pan. Top with almond flour to soak up the extra fruit juices. Sprinkle the Streusel on top. Finally, spread the cake batter over the top and bake in the oven for 35 minutes.

    What Flour Makes This Cake Gluten Free?

    I use King Arthur's Gluten-Free Flour for this recipe. The almond flour in this gluten-free plum cake recipe is also gluten-free.

    Streusel vs. Crumble

    This recipe calls for an American streusel topping. There is a difference in the textures of German Streusels and American Streusels. I am choosing to make my recipe with American Streusel because that's what I grew up eating. My grandma was part German and made the American version of Streusel.

    Substitutions

    • Almond flour - instead of pre-made almond flour, you can use ground almonds that you grind yourself into almond meal.
    • Vanilla extract - use almond extract or omit it completely. 

    Variations

    • Maple Syrup - add 1 teaspoon maple syrup to the Streusel before baking for a nutty taste. 
    • Coconut - add shredded coconut to the Streusel before baking for gluten-free coconut plum cake.
    • Almond extract - add 1 teaspoon almond extract to the batter for a plum and almond cake recipe. A plum and almond cake would be delicious, too!

    Equipment

    • Glass mixing bowls
    • 9-inch cake pan

    Storage and freezing

    Store plum cake at room temperature in an airtight container for up to three days. 

    To freeze, wrap the cake in plastic wrap and store it in a freezer-safe plastic bag. Freeze for up to three months. Let the cake sit overnight at room temperature to thaw.

    Top tip

    Don't be afraid of the Streusel! This is a crumbly cake. It's similar to a scone texture. Top with fresh whipped cream and sliced plums.
