Recipe Info:

  • Prep Time: 25 minutes
  • Cook Time: 45 minutes
  • Total Time: 70 minutes
  • Yield: 8-10 servings

Ingredients

For the Streusel Topping:

  • 1/2 cup (60g) all-purpose flour
  • 1/4 cup (50g) granulated sugar
  • 1/4 cup (50g) packed light brown sugar
  • 1 teaspoon ground cinnamon
  • 1/4 cup (56g) cold vegan butter, cut into small cubes

For the Cake:

  • 1 1/2 cups (180g) all-purpose flour
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup (113g) vegan butter, softened
  • 3/4 cup (150g) granulated sugar
  • 1 tablespoon apple cider vinegar (or lemon juice)
  • 1 teaspoon vanilla extract
  • 1 cup (240ml) unsweetened plant-based milk (almond, soy, or oat)
  • 1 1/2 cups (about 200g) fresh strawberries, hulled and chopped
  • 1 1/2 cups (about 200g) fresh rhubarb, trimmed and chopped into 1/2-inch pieces
  • 1 tablespoon all-purpose flour (for tossing with fruit)

Step-by-Step Instructions

  1. Prepare the Streusel: In a medium bowl, whisk together the 1/2 cup flour, granulated sugar, brown sugar, and cinnamon. Add the cold, cubed vegan butter. Using your fingertips or a pastry blender, cut the butter into the dry ingredients until coarse crumbs form. The mixture should resemble wet sand with some pea-sized clumps. Set aside.
  2. Preheat Oven & Prepare Pan: Preheat your oven to 375°F (190°C). Lightly grease and flour a 9×9 inch square baking pan or a 9-inch round springform pan. Line the bottom with parchment paper if using a springform.
  3. Combine Dry Ingredients: In a large bowl, whisk together the 1 1/2 cups flour, baking powder, baking soda, and salt. Set aside.
  4. Cream Wet Ingredients: In a separate large bowl, using an electric mixer, cream together the softened vegan butter and 3/4 cup granulated sugar until light and fluffy, about 2-3 minutes. Beat in the apple cider vinegar and vanilla extract until well combined.
  5. Alternate Wet and Dry: Gradually add the dry ingredients to the wet ingredients, alternating with the plant-based milk, beginning and ending with the dry ingredients. Mix on low speed until just combined. Be careful not to overmix; a few small lumps are fine.
  6. Prepare the Fruit: In a small bowl, gently toss the chopped strawberries and rhubarb with the remaining 1 tablespoon of flour. This helps prevent the fruit from sinking to the bottom of the cake and absorbs excess moisture.
  7. Fold in Fruit: Gently fold the floured fruit into the cake batter until evenly distributed.
  8. Assemble & Bake: Pour the batter into the prepared baking pan and spread evenly. Sprinkle the streusel topping generously over the entire surface of the batter.
  9. Bake: Bake for 45-55 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The streusel should be golden brown and the cake edges lightly browned.
  10. Cool: Let the coffee cake cool in the pan on a wire rack for at least 20-30 minutes before slicing and serving. This allows the cake to set properly and prevents it from crumbling.

Pro Tips for Success

  • Don’t Overmix the Batter: Overmixing develops gluten, which can lead to a tough, dense cake. Mix until just combined; a few small lumps are perfectly acceptable and even desirable for a tender crumb.
  • Proper Rhubarb Preparation: Always trim the very ends of the rhubarb stalks and discard any leaves, as they are toxic. Chop the stalks into uniform 1/2-inch pieces so they cook evenly and integrate well into the cake.
  • Temperature Matters for Vegan Butter: For the streusel, ensure your vegan butter is cold and firm to create distinct, crumbly clumps. For the cake batter, use softened, room-temperature vegan butter for a smooth, airy creaming process that incorporates air for a lighter cake.
  • Flour the Fruit: Tossing the chopped strawberries and rhubarb with a tablespoon of flour before folding them into the batter is a crucial step. This light coating helps the fruit suspend evenly throughout the cake and prevents it from sinking to the bottom, while also absorbing some of the fruit’s natural juices to avoid a soggy cake.

Variations & Substitutions

  • Gluten-Free Option: For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum. Ensure all other ingredients are certified gluten-free.
  • Fruit Swaps: Feel free to experiment with other seasonal fruits. Blueberries, raspberries, or even diced peaches would be delicious in place of or in combination with the strawberries and rhubarb. Adjust sugar slightly if using very sweet or very tart fruits.
  • Spice It Up: Add a pinch of ground ginger or cardamom to the cake batter for an extra layer of warm spice that complements the fruit beautifully.
  • Sugar Alternatives: You can substitute granulated sugar with coconut sugar for a slightly less sweet, more caramel-like flavor. The texture may be a bit denser.

Serving Suggestions

Serve this delightful Vegan Strawberry Rhubarb Coffee Cake warm or at room temperature. It’s absolutely perfect for a weekend brunch spread, perhaps alongside a fresh fruit salad and a pot of your favorite coffee or tea. For a more indulgent dessert, a scoop of vegan vanilla ice cream or a dollop of coconut whipped cream makes an exquisite accompaniment. It also makes a wonderful afternoon treat with a cup of herbal tea.

Storage & Reheating

This coffee cake is best enjoyed fresh, but leftovers store beautifully. Store any remaining cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 4 days. For longer storage, wrap individual slices tightly in plastic wrap and then aluminum foil, and freeze for up to 2-3 months. To reheat, thaw frozen slices in the refrigerator overnight, then warm in a preheated oven at 300°F (150°C) for 10-15 minutes, or microwave individual slices for 30-60 seconds until warmed through.

Frequently Asked Questions

Can I make this coffee cake ahead of time?

Yes, you can! You can prepare the cake batter and fruit mixture, then store them separately in the refrigerator overnight. Assemble and bake the next day. Alternatively, bake the entire cake, let it cool completely, and store it as directed in the “Storage & Reheating” section.

Can I use frozen strawberries or rhubarb?

Absolutely. If using frozen fruit, do not thaw it first. Toss the frozen fruit directly with the tablespoon of flour as instructed. Be aware that frozen fruit may release more moisture, so the baking time might be slightly longer. The cake might also have a slightly softer texture.

How do I prevent the fruit from making the cake soggy?

The key is to toss the chopped strawberries and rhubarb with a tablespoon of flour before folding them into the batter. This light coating helps absorb excess moisture released by the fruit during baking and creates a barrier, preventing a soggy bottom and ensuring the fruit stays suspended throughout the cake.

This Vegan Strawberry Rhubarb Coffee Cake is more than just a recipe; it’s an invitation to savor the simple pleasures of seasonal baking. With its tender crumb, vibrant fruit, and irresistible streusel, it promises to be a delightful addition to your table, bringing warmth and joy to any occasion.
