This cake is my contribution to the #LovePrideCollab on Instagram that was created to bring awareness to the LGBTQ community and celebrate diversity, equality and inclusion. The collaboration is fundraising for The Trevor Project, which aims to end suicide among the LGBTQ youth.
I decorated this cake in the style of my Blood Orange Layer Cake. The base recipe, however, is from my Easy Strawberry Crunch Cupcakes. I just added rainbow sprinkles to make it more festive and doubled the frosting to have plenty to decorate with.

How to make homemade funfetti cake
Step 1: Combine all of the wet ingredients with a whisk in a large bowl.
Step 2: Whisk together the dry ingredients in a separate bowl and add them to the wet ingredients.
Step 3: Add the sprinkles and gently fold them in just until combined.
Step 4: Divide the batter evenly between the prepared tins and bake.
Hot tips
- Help eggs from the fridge come to room temperature quickly by placing them in warm water as you prep the other ingredients.
- Use a thin knife or offset spatula to help shimmy the dried sprinkles away from the parchment paper.
- If your frosting is too runny, chill for 30 minutes in the refrigerator to firm up before decorating.
- Place the bench scraper in a bowl of warm water before using it (drying it off in between) to help remove air bubbles on the outside and make smoothing easier.

Instructions
Do ahead
- If making the homemade sprinkles, they MUST be made the day before as they need to dry out overnight.
Make the sprinkles
- Combine the powdered sugar, water, corn syrup and vanilla in a medium bowl with a whisk until there are no lumps. If coloring rainbow style, divide between 6 smaller bowls. Color each bowl with red, orange, yellow, green, blue and purple food coloring respectively.
- Transfer each color to a piping bag fitted with a small round piping tip. Lay out 6-8 large sheets of parchment paper on your workspace. Pipe long straight lines of each color. Pipe them a bit longer than the length you plan on using so you can cut the ends to clean them up. I cut mine to 6-inches long for my cake.
- Let dry uncovered at room temperature overnight.
Make the cake
- Grease two 6-inch round cake tins and line the bottoms with a circle of parchment paper. Preheat the oven to 350°F.
- Thoroughly whisk together the flour, sugar, salt, baking powder and baking soda in a medium bowl.
- In a large bowl, whisk together the eggs, sour cream, oil, lemon juice, vanilla and almond extract. Add the dry ingredients to the wet ingredients and fold with a rubber spatula just until there are no longer any streaks of flour. Add the sprinkles and fold just until combined. Do not overmix.
- Divide the batter evenly between the prepared tins. Bake for 25-28 minutes or until a toothpick inserted in the center comes out clean.
- Let the cakes cool in the tins for at least 30 minutes before gently removing the cake layers to a wire rack to cool completely.
Make the frosting
- Beat the cream cheese with beaters or in the bowl of a stand mixer fitted with a paddle attachment until completely smooth and no lumps remain. Remove to a small bowl.
- Place the room temperature butter in the stand mixer bowl or regular bowl that the cream cheese was just in. Beat on high for 3-4 minutes or until smooth and fluffy.
- Add the cream cheese to the butter and beat until combined, 1-2 minutes.
- Add the powdered sugar and beat until combined. Add salt, lemon juice and vanilla. Beat until combined. You may want more powdered sugar depending on your desired sweetness and consistency*.
Assemble the cake
- Prep the homemade sprinkles, if using, by gently peeling away from the parchment paper. Cut down to 6-inch sections.
- Level the cake layers by slicing off any domed tops. Slice the cake layers in half to create four thin cake layers.
- Place a small dollop of frosting onto your serving plate or cake board. Place the first sturdiest cake layer on top. Pipe or spoon a layer of frosting on top. Repeat with remaining cake layers.
Crumb coat
- Coat the cake in a very thin layer of frosting, smoothing the sides and top with an offset spatula or bench scraper. Chill in the freezer for at least 10 minutes to set it. This locks in any crumbs that could ruin your final coat of frosting.
Decorate the cake
- When the crumb coat is set, pipe or dollop more frosting around the outside and on top. Spread evenly with an offset spatula before scraping down the outside with a bench scraper. You may need to do this several times to get a smooth look.

- Cover the outside with the tall sprinkles, standing straight up. I followed the rainbow pattern (red, orange, yellow, green, blue, purple), using two of each color at a time.
