Easy Berry Reduction
Berry reduction is a concentrated berry puree that adds fresh berry flavor to dessert recipes. In this baking tutorial post, I will teach you how to make berry reduction and how to use it to make berrylicious desserts!

What is Berry Reduction?
Berry reduction is a concentrated berry puree. Different types of berries are cooked, reduced, and pureed to create a flavorful sauce that can be used to add delicious berry flavor to frosting, cakes, cupcakes, and more! It adds fresh berry flavor to recipes rather than using extracts.
There is only one ingredient required – frozen berries! You could use frozen raspberries, strawberries, blueberries, blackberries, or a mixed berry blend. Because I use berry reduction as an ingredient in many of my recipes, there are no additional ingredients added, including sweeteners or lemon juice.
Tools & Supplies

How to Make the Berry Reduction
The process for making the reduction is the same no matter what type of berry you are using. To make approximately 1/2 cup, you will need 2 cups of frozen berries.
- Add 2 cups of frozen berries to a medium saucepan. Simmer the berries over medium-low heat and stir occasionally. As the berries soften, use a wooden spoon to mash and break up the berries. Continue to cook the mixture at a gentle boil for about 10-15 minutes until it reduces and thickens slightly.
- Remove the saucepan from the heat. Use an immersion blender or transfer the reduced berry mixture to a food processor or blender and pulse until smooth. The mixture will be very hot, so be careful.
- Run the sauce through a fine mesh strainer to remove any seeds.
- Transfer to a heatproof bowl and cool completely.
When you are adding berry reduction to a recipe, it is best to add it in at room temperature.
How to Use the Berry Reduction
You can use berry reduction in various types of desserts to add fresh berry flavor and a beautiful bright color. Here are just a few recipes that include berry reduction as an ingredient!
- Cakes – Strawberry cake
- Cupcakes – Strawberry cupcakes
- Buttercream – Raspberry buttercream & strawberry buttercream
- Bars – Raspberry lemon bars
You could also drizzle it over pancakes, waffles, French toast, vanilla ice cream, cheesecake, or greek yogurt. Just keep in mind that because there is no sweetener, the reduction may have a bit of a tart taste. I personally love the contrast between a sweet and creamy dessert like cheesecake with the fresh and tart taste of berry reduction.
Conversions
Here are the approximate conversions of the berry reduction depending on the amount you need for the recipe.
- 4 cups frozen berries = 1 cup reduction
- 3 cups frozen berries = 3/4 cup reduction
- 2 cups frozen berries = 1/2 cup reduction
- 1 cup frozen berries = 1/4 cup reduction

Frequently Asked Questions
How can I store the berry reduction?
- Make the berry reduction ahead of time and store it in an airtight container in the refrigerator for about 1 week.
Can I use fresh berries instead of frozen?
- I highly recommend going with frozen berries for the best results.
- If you want to use fresh berries, you could either freeze them overnight or add a few tablespoons of water to the berries before you start cooking.
What should I do if my buttercream separates after I add the berry reduction?
- Adding the reduction to buttercream can cause it to separate a little bit because we are adding a water-based substance to a fat-based substance.
- If your frosting appears to separate, just keep whipping it for several minutes. It will come together to create a smooth and ready buttercream frosting.
Why don’t you add any sweetener to the reduction?
- Because I treat berry reduction as an ingredient, I don’t like to add any sweetener. This way, you are able to control the sweetness of the recipe and not add any additional sweetness.

Can fresh blueberries be used for the reduction?
Hi Libby! I have tried using fresh blueberries and the reduction can sometimes come out a bit thick. You can use fresh blueberries, but you may need to add a tablespoon or two of water to the blueberries.
This sounds delicious! Question- Can this Berry reduction be frozen for use later?
Hi Teri! Great question. I’ve tried freezing it I’ve noticed that it doesn’t freeze very well. What I do if I have extra berry reduction is add a bit of honey or maple syrup to it with chia seeds and make a quick chia jam!
