What You Need to Make Plum Coffee Cake at Home

All you need are some simple pantry staple ingredients to make this gluten-free plum coffee cake recipe at home. Let's look at them in more detail:

• Gluten-free baking flour: We will be needing gluten-free baking flour to make this recipe. It will provide structure and texture to the final product, and guarantee a light and fluffy result. 
• Almond flour: We will also need some almond flour. It will add a nutty flavor and a moist texture to the baked goods, making them rich and delicious.
• Xanthan gum: Next we will be using xanthan gum. It will act as a binding agent, preventing the baked goods from crumbling and giving them a cohesive texture. 
• Baking powder: We will also need some baking powder. It will help the batter rise and create a light and airy texture in our coffee cake.
• Baking soda: Remember to use baking soda. It will react with the acid in the ingredients, causing the batter to leaven properly to give you a deliciously moist and fluffy cake.
• Sea salt: We will also need sea salt. It will enhance the flavors of all the ingredients and balance out the sweetness, making the final product taste even better.

• Eggs: We will need eggs to make this recipe. They will provide structure, moisture, and richness to coffee cakes, resulting in a tender and flavorful final product. 
• Sugar: You’ll also use some sugar! It will add just the right amount of sweetness to our cake to give us the most delicious coffee cake ever. 
• Vanilla extract: We will also be needing vanilla extract. It will add a fragrant and aromatic flavor to our coffee cake.
• Coconut oil: We will also need coconut oil which has been melted and cooled to make this recipe. It will add moisture and richness to the cake.

• Plums: And, of course, we’ll also need some plums. I’ve used homegrown Damson plums but you can use whichever ones are available to you. They will provide a burst of juicy and tangy flavor, adding a delicious fruity element to our coffee cake.

How to Make Plum Coffee Cake (Step by Step)

Making this incredible gluten-free plum coffee cake is easier than you think. Here's how to make them at home step by step:

How to Make Plum Coffee Cake Batter

To make this simple gluten-free plum coffee cake, start by rinsing the plums under running water. Then, take a knife and cut each plum in half, running the knife all the way around the pit. Separate the fruit into two halves, one with the pit and one without. Remove and discard the pit.

Next, take each half of the plum and cut it in half again, or into two wedges if the plum is large. Dice all of the plum wedges and place them into a large bowl. Repeat this process with the remaining plums.

Now sprinkle the diced plums with gluten-free flour and make sure to coat them evenly. Set the plums aside for now.

Preheat your oven to 350 degrees Fahrenheit (180 degrees Celsius). Grease a 9-inch round springform pan with butter or coconut oil.

In a medium glass bowl, sift together the gluten-free and almond flour. Add the rest of the dry ingredients to the bowl: baking powder, baking soda, Xanthan gum, and sea salt. Stir all of the dry ingredients together using a hand whisk until they are well combined. Set this mixture aside for later.

Next, beat the sugar and eggs on high speed in a mixing bowl until they become foamy and pale in color. This should take about 5 minutes. Reduce the mixing speed to low and add the vanilla extract, melted and cooled coconut oil. Continue mixing for another minute.

Remove the bowl from the mixer attachment and add the flour mixture to the wet ingredients in three separate additions. Gently fold in the flour after each addition to avoid deflating too many air pockets in the batter. These air pockets are important for achieving a fluffy texture in the cake.

Finally, add ¾ of diced and coated plums to the batter and gently fold them in.

How to Bake Plum Coffee Cake

Transfer the batter to the greased round pan that you prepared earlier. Sprinkle the remaining ¼ of the diced plums over the top of the batter.

Bake the cake in the preheated oven for about 35 minutes, or until an inserted toothpick comes out clean. Once the cake is baked, remove it from the oven and let it cool in the baking pan for 5 minutes. Then, transfer the cake onto a cooling rack to cool completely.

When the cake has cooled down to a warm temperature, sprinkle the top with organic powdered sugar. Slice the cake and enjoy!

Tips for Making the Best Plum Coffee Cake Ever

Preparing the plums: Before adding the plums to the coffee cake batter, make sure to wash them thoroughly and remove any pits. 

Choosing the right gluten-free flour: To achieve a light and fluffy texture in the coffee cake, use a gluten-free flour blend that includes a mix of different flours, such as rice flour, tapioca flour, and potato starch. Avoid using just one type of gluten-free flour, as it can result in a dense and heavy cake.

Measuring the flour accurately: When measuring the gluten-free flour, spoon it into the measuring cup and level it off with a knife. Avoid packing the flour into the measuring cup, as this can lead to too much flour and a dry cake..

Testing for doneness: To check if the coffee cake is fully cooked, insert a toothpick into the center. If it comes out clean or with just a few crumbs clinging to it, the cake is done. If the toothpick comes out with wet batter, the cake needs more time in the oven.

Allowing the cake to cool before serving: After baking, let the coffee cake cool in the pan for about 10 minutes before transferring it to a wire rack to cool completely. This allows the cake to set and prevents it from falling apart when slicing. Once cooled, serve the cake at room temperature or slightly warmed.

Serving Suggestions for Gluten-free Plum Coffee Cake

1. Enjoy a slice of this plum coffee cake on its own for a delicious and satisfying breakfast or snack. The moist cake, sweet plums, and crumbly topping make for a perfect combination.
2. Serve this plum coffee cake warm with a scoop of vanilla ice cream for a delightful dessert. The warm cake and juicy plums pair perfectly with the cold and creamy ice cream, creating a mouthwatering treat.
3. For a brunch or afternoon tea, serve this coffee cake with a side of whipped cream or yogurt. The tanginess of the whipped cream or yogurt compliments the sweetness of the plums and adds a creamy element to the dish.
4. Cut the coffee cake into smaller squares and serve it as part of a dessert platter. Add some fresh berries, a drizzle of chocolate sauce, and a sprinkle of powdered sugar for an elegant dessert presentation.
5. Toast a slice of this coffee cake and spread it with butter or cream cheese for a simple yet delicious breakfast option. The creamy spread adds richness to the cake, making it even more enjoyable.

Recipe Variation Ideas for Plum Coffee Cake

This delicious gluten-free plum coffee cake recipe is absolutely perfect as is, but if you're looking to change things up, here are a few variation ideas you can try:

Blueberry: Add fresh or frozen blueberries to the batter before baking for a burst of fruity flavor. Blueberries pair well with the tender cake and add a pop of color to the final result.

Cinnamon streusel: Prepare a cinnamon streusel topping by mixing together brown sugar, cinnamon, and melted butter. Sprinkle the streusel over the cake batter before baking to create a deliciously crunchy and sweet topping.

Lemon poppy seed: Add the zest of one lemon and a tablespoon of poppy seeds to the batter for a bright and tangy twist. The lemon adds a refreshing flavor while the poppy seeds provide a subtle crunch and visual appeal.

Chocolate chip: Fold in a cup of chocolate chips into the batter for a delicious treat. The melted chocolate chips create pockets of goodness throughout the cake, making it a perfect choice for chocolate lovers.

Apple cinnamon: Peel and dice one or two apples, then mix them into the batter along with a teaspoon of cinnamon. The combination of tender apples and warm cinnamon creates a cozy and comforting cake that is perfect for fall or winter.

Frequently Asked Questions

Can I make this coffee cake in advance?

Yes, you can make this coffee cake in advance. Simply bake the coffee cake, let it cool completely, and store it in an airtight container at room temperature for up to 3 to 4 days. You can also refrigerate it for longer storage or even freeze it!

How to Store Leftover Gluten-free Plum Coffee Cake

To store leftovers, first allow the cake to cool completely. Then, cover it tightly with plastic wrap or transfer it to an airtight container. Store the cake in the refrigerator for up to 3-4 days.

When you’re ready to enjoy the leftovers, you can either eat the cake cold or reheat it in the oven or microwave. To reheat in the oven, preheat it to 350°F (175°C) and place the cake on a baking sheet. Heat for about 10-15 minutes or until warmed through. 

To reheat in the microwave, place a slice of the cake on a microwave-safe plate and heat for 20-30 seconds or until desired temperature is reached. I also like to use a toaster oven and reheat a slice of frozen cake for a minute or so and it works great.

You can easily freeze your plum coffee cake in the freezer as well. Allow it to cool down and then slice the cake and cover it with plastic wrap and pop it into a freezer safe container. Reheat as instructed above whenever you want to enjoy a slice.
