Panera partnered with Nothing Bundt Cakes and I grabbed this adorable palm-sized lemon cake with my coffee! The cake is incredibly moist with bright citrus flavor, and the white icing glaze adds just the right sweetness without being cloying. It's the perfect single-serve treat. Collaboration done right.
Preheat your oven to 350°F. Generously grease a 6-well mini Bundt pan to ensure easy release—the signature clean edge is key, just like Panera's single-serve Bundtini.
In a stand mixer (or with a hand mixer), cream the softened butter and granulated sugar on medium speed for at least 3 minutes until light and fluffy. This builds the moist, tender crumb Panera is known for.
Beat in the eggs one at a time, scraping down the bowl. Add lemon zest, lemon juice, sour cream, vanilla extract, and milk, mixing until fully incorporated. Mixing dairy with citrus at this stage creates that bright, rich flavor found in Panera's lemon cakes.
In a separate bowl, whisk together flour, baking powder, and kosher salt. Add dry ingredients to wet in two batches, mixing gently until just combined. Do not overmix; overmixing reduces the cake’s tender texture.
Divide batter evenly among the Bundt wells (about two-thirds full). Bake for 20–24 minutes until a toothpick comes out clean and edges are lightly golden. Cool in the pan for 10 minutes, then turn out onto a rack.
While cakes cool, make the glaze: beat cream cheese and butter together until creamy. Add powdered sugar and 2 tbsp lemon juice, mixing until smooth and thick but pourable. For the classic Panera look, pipe or drizzle glaze generously over each Bundtini once fully cooled.
