Ingredients
- Chopped rhubarb stalks: The star ingredient that brings a zingy tartness Choose stalks that are firm and vividly pink for best flavor
- Granulated sugar: Sweetens both the jam and the batter Look for fine baking sugar so it dissolves easily
- Salt: Enhances all the flavors and balances the sweetness
- Water: Helps break down the rhubarb as it cooks Any filtered water works
- Vanilla extract: Adds a warmth to both the jam and the batter Pure vanilla extract gives the best taste
- Honey: Blends with the rhubarb for a mellow sweetness Go for local or wildflower honey if possible
- Salted butter: Gives moisture and richness to the cupcakes Use high quality European style butter if you can
- Large eggs: Binds the batter and contributes to the light crumb Use room temperature eggs for best mixing
- Sour cream: Makes the cupcakes extra moist and tender Full fat is best for richness
- Milk: Keeps the batter soft and light Whole milk provides creaminess
- Cake flour: Creates a soft and airy cupcake crumb Opt for bleached cake flour if available
- Baking soda and baking powder: These work together for the perfect fluffy rise Check that they are fresh and active
- Powdered sugar: Used in the buttercream for smooth sweetness Choose finely sifted sugar for no lumps
- Tips: Select rhubarb at peak season in spring or early summer and avoid stalks with lots of green or woody ends
Instructions
- Prepare the Rhubarb Honey Jam:
- In a large saucepan over medium high heat combine chopped rhubarb sugar salt and water Stir occasionally letting the rhubarb break down and the sauce thicken for roughly ten minutes Watch that nothing sticks or burns and reduce heat if bubbling too rapidly
- Add Honey and Vanilla to the Jam:
- Once the sauce is thick remove from heat Stir in honey and vanilla extract Let the jam cool to room temperature so it thickens enough to fill cupcakes
- Make the Cupcake Batter:
- In a large bowl cream the butter and sugar together until fluffy and pale Beat in eggs vanilla milk and sour cream until smooth Add cake flour baking powder baking soda and salt gently mixing just until combined and only a few small lumps remain
- Fill and Bake the Cupcakes:
- Line cupcake pans with paper liners Using a scoop or spoon fill each about three quarters full Tap the tray lightly to release air bubbles Bake at three hundred fifty degrees for twenty five minutes or until a toothpick comes out clean Let cupcakes cool completely on a wire rack before filling or frosting
- Prepare the Rhubarb Buttercream:
- In a clean bowl beat softened butter and cooled rhubarb sauce together until totally smooth and creamy Stir in vanilla blend again then gradually add powdered sugar beating well after each addition until frosting is fluffy and light pink
- Core and Fill the Cupcakes:
- Once cupcakes are fully cooled use a spoon or scoop to remove about one tablespoon from the center of each Fill with two teaspoons of rhubarb honey jam Place the piece of cupcake you removed back on top to cover the jam center
- Frost the Cupcakes:
- Pipe or spread the rhubarb buttercream generously onto each filled cupcake Top with a decorative swirl and store in an airtight container to keep fresh

My favorite part of this recipe will always be seeing the swirls of pink buttercream on a platter during family celebrations The color always brings extra smiles to the table and it reminds me of my grandmother’s kitchen filled with springtime rhubarb
Storage Tips
Store cupcakes in an airtight container at room temperature for up to two days Longer than that and the buttercream and jam will need refrigeration Allow to come to room temperature before serving so the cake stays soft If you make the rhubarb sauce ahead it can be kept in the fridge for up to a week
Ingredient Substitutions
No sour cream on hand Plain full fat Greek yogurt makes a great swap Both keep the cake perfectly moist If you cannot find cake flour use all purpose flour mixed with a little cornstarch Spoon and level your flour for professional results Clover honey offers a different but lovely floral note if wildflower is not available
