Mix cake mix, butter, eggs and milk. Pour into greased mini bundt pan and bake 20-25 minutes. Let cool and remove from pan.
To make chocolate toppers: In bowl for each color, melt melting chips in 1-minute intervals in microwave until thoroughly melted. Pour into baggies and snip corner. Pipe melted chips into molds and freeze 15-20 minutes. Pipe green icing onto mini bundt cakes for “grass” then place chocolate mold pieces on top.
Notes
Substitution: Save time on toppers by replacing with store-bought chocolate bunnies, eggs, crosses or marshmallow bunnies.
